Algal biomass gasification efficiencies
Suffice to say i have had cross contaminations of euglena species throughout all of my samples so far.
I suspect that is has somehow travelled through my single air/co2 pump system and into the isolated cultures.
At this point it would be easy to say that euglena is an enemy/parasite of my algaculture endeavors.
But sometimes it is necessary to take a step back and ask. IS IT AND ENEMY or is it just more prolific?
It would be easy to just state it us an enemy or parasite and 'attempt' to take additional measures to eliminate euglena from the samples. But that is MORE TIME AND MORE EXPENSE to try to eliminate a USEFULL SPECIES.
I have been doing extensive studies ans a myriad of thought experiments on how to keep euglena out of the samples. Unless on has a clean roon type of laboratory at hand and extensive protocols in place and of which can be continuously inplemented. ITNOS VERY EXPENSIVE.
However, on the other hand. After aeeing the success of my fathers development of a gasification of wood chips ( a different for of biomatter ) to produce hydrogen rich syngas capable of turning a 10,000 watt electric generator. I have been researching the feasibility of using dry algae for gasification syngas generation and have found that it is not only feasible but VERY Efficient.
This conclusion is that using natural PROLIFIC INVASIVE species of algae or euglena in an open pond / raceway environment to WORK WITH NATURE to produce euglena/ algal biomass to more efficiently produce biomass for gasification instead of focusing on producing algae OIL for biodiesel production using unnatural, sterile an expensive laboratory environment is more efficient and more natural.
So my focus then ia to focus on producing as much algal biomass as possible and not focus so much on OIL for BIODIESEL production which, from my research, is inefficient and in exorbitantly costly.
AND ALSO IN CREATING A SMALL SCALE ALGAE GASIFICATION SYNGAS GASIFIER.

intresting 5 gallon water bottle - photobioreactor design
More research on Euglena - can it be used for Biofuel production??
here is an informative article on Encyclopedia Britannica - https://www.britannica.com/science/Euglena
Euglena are characterized by an elongated cell (15–500 micrometres [1 micrometre = 10−6 metre], or 0.0006–0.02 inch) with one nucleus, numerous chlorophyll-containing chloroplasts (cell organelles that are the site of photosynthesis), a contractile vacuole (organelle that regulates the cytoplasm), an eyespot, and one or two flagella. Certain species (e.g., E. rubra) appear red in sunlight because they contain a large amount of carotenoid pigments. Unlike plant cells, Euglena lack a rigid cellulose wall and have a flexible pellicle (envelope) that allows them to change shape. Though they are photosynthetic, most species can also feed heterotrophically (on other organisms) and absorb food directly through the cell surface via phagocytosis (in which the cell membrane entraps food particles in a vacuole for digestion). Food is often stored as a specialized complex carbohydrate known as paramylon, which enables the organisms to survive in low-light conditions. Euglena reproduce asexually by means of longitudinal cell division, in which they divide down their length, and several species produce dormant cysts that can withstand drying.
http://link.springer.com/article/10.1007/s10811-013-9979-5
Euglenoids achieved a maximum lipid content of 24.6 % (w/w) with a biomass density of 1.24 g L−1 (dry wt.).
The japanese company - apply named EUGLENA - states -
Euglena's oil formation is suited for jet fuels
High productivity and efficient land use
Productivity per acre is also significantly higher compared to many other feedstocks.
In our laboratory in Tokyo University, we have achieved 15 times higher productivity compared to palm oil.
Alternative fuel
On the other hand euglena absorbs CO2 from the atmosphere during production so there is a chance of reducing CO2 emission
if there are further technical developments.
http://biofuels-news.com/ has another article on euglena - DECEMBER 2, 2015 - Japanese Euglena to establish an algae-based jet fuel demo plant
(Algae Industry Magazine) Scientists at the John Innes Centre, in Norwich, England, have discovered that Euglena gracilis, the single cell algae that inhabits most garden ponds, has a whole host of new, unclassified genes that can make new forms of carbohydrates and natural products.
Even with the latest technologies, sequencing the DNA in Euglena remains a complex and longwinded undertaking. Dr. Ellis O’Neill and Professor Rob Field from the John Innes Centre have therefore sequenced the transcriptome of Euglena gracilis, which provides information about all of the genes that the organism is actively using.
The team also found that different sets of genes become active when Euglena is grown in the dark to when it is grown in the light. This indicates that Euglena can dramatically shift its metabolism depending on its environment, which reflects its ability to live successfully in varied environments.
Euglena creates many well-known, valuable natural products including vitamins, essential amino acids and a sugar polymer, which is reported to have anti-HIV effects. Given the usefulness of the compounds we know about, these findings have the potential, with further research, to lead to the discovery of new medicines including new antibiotics, nutrients and new forms of biofuel, among other products.
Biofuel from Euglena
09 March 2010Euglena, meaning “beautiful eye”, is a single-celled algae that can be found in lakes, ponds, and even puddles. It was named after Leeuwenhoek, a microscope inventor in the 17th century, who incidentally found Euglena through the lens. Euglena has the characteristics of both animal and plant, where it moves around like an animal, and photosynthesises like a plant.
The joint venture has a culturing system in place that can be used to grow Euglena efficiently and the yield is better than crops such as corn and sugar cane usually used to produce biofuel, a report in Crunch Gear says.
The company is trying to lower the cost of production to 80 cents a litre to make biofuel production competitive.
The company says mass-producing Euglena-derived biofuel should be possible by 2015.

Life cycles algae & plants

|||||
Organisms, from little moss to
man, go during their life through a number of biological phases, generation
after generation. The following "biological phases" are encountered
during the life cycle: the formation of gametes (the
sexual reproductive cells), the fusion of male and female gametes (~ fertilization)
to a zygote, and a period of growth and development (cell
differentiation and morphogenesis) that occurs at various time sequences,
depending on the phylogenetic group to which the organism belongs. Within the
life cycle, meiotic divisions (more) take place, in
which cell proceed from a diploid to a haploid stage;
in the diploid stage two homologous copies of each chromosome are present in
the cells and in the haploid stage only one sample of each chromosome in
present in each cell. Gametes are always haploid, whereas zygotes are
diploid. Furthermore, during the life cycle mitotic divisions occur
(more about
mitosis). Depending on the phylum to which the organism belongs, these
mitotic divisions occur in the haploid, or diploid phase, or in both the
haploid and diploid stages. More here about here below.
In these web modules one finds descriptions of the life cycles of brown, red and green algae and that of various phyla of land plants. The characteristics are shown according to typical representants of each group, the same as those that are discussed in the course "Evolution and Development of the Plant" (Radboud University Nijmegen). The classification and terminology in these webpages follows the handbook that is used during lectures and practical courses: "Biology, Campbell, Reece, Urry, Cain, Wasserman, Minorsky en Jackson, 2008. Pearson International Edition (eds).San Francisco. 1267 pp".
Three types of life cycles can be distinguished on account of the timing of
the mitoses, in the haploid and/or diploid phase:

This series webpages on the life
cycle in plants is based on course notes and other teaching material of Mieke
Wolters-Arts, Celestina Mariani, Jan Derksen, the late G. van den Ende and
Luud J.W. Gilissen. Dr Gerard van den Ende had developed an extended manual
enriched with numerous drawings of life cycles, which went along with the
practical courses that he taught. The microscopical work and the layout are

Inoculation of 50ml growth culture take from petri dish cultures into 500ml growth media.
After 5 days growth of media taken from the front yard growth media petri dish sample and inoculate a 500 ml growth media.
Before this I examined the sample under microscope and found nothing but what I am labeling Characium pringsheimii based upon visual comparison.
very distinctive structure
More Characium pringsheimii from FY11-01-2016
I also found a couple of cells that had apparently ruptured and captured a small video of parasites feeding on the expelled inards.
Ankistrodesmus acicularis for Percy Priest Lake
I examined the specimen under microscope and found several species of algae in the sample, including Ankistrodesmus acicularis.

We have algae culture growth in petri dish!!!
AGAIN, the algae from the front yard pond grew successfully on the miraclegro algae agar from the recipe in my previous post from Doane College Algae Lab YouTube videos.
Here is a great link to all of their pertinent video series. Awesome resource!!
http://doanealgae.wixsite.com/algaegrowingresource/videos
And now the images of my petri dishes!! MESSY MESSY.
Being overly excited to cultivate a single species I have created 3 50 ml glass culture bottles made from Cracker Barrel maple syrup bottles!! I took small 'single colony' scrapping from 3 seperate areas and added to the bottles.
Here is day one images -
I have Characium pringsheimii - i think
Genus: Unicellular; cell body ellipsoidal or spindle-shaped, attached on a substrate at one end; a single chloroplast plate-like in shape, with a pyrenoid (Guide book to the "Photomicrographs of the Freshwater Algae", 1998).

OMG Euglena eat algae!!! OH HAYUL NAW!!!
Euglena gracilis and other euglena are green because they eat green algae. They keep the algae inside their bodies and use it to make their own food. These green parts inside the Euglena's body are called chloroplasts.
SO I HAVE IDENTIFIED AN ALGAE EATER IN MY ALGAE!!!
OH HELL NAW!!!
Using Microscope Attempt to identify algae species
Here are reference images of my summer algae sample that shows no sign of dying after 5 months.
And some videos
- Algae are unicellular - not joined to neighbouring cells
- Cell wall is smooth, cell outline round to ellipsoidal, and featureless
- Cells containing membrane-bound organelles, such as chloroplasts and nuclei.
- Cell with rigid cell wall, lacking shallow groove at equator, and motile, propelled by one or more waving hair-like structures (flagella) - EXCEPT I CAN NOT SEE FLAGELLA, my microscope may just not be good enough to resolve - but had to say this to get to spindle shape..
- Unicellular chlorophyte with an elongated, usually spindle-shaped cell with two short flagella emerging from one end. There is a single chloroplast that may contain a visible eyespot. If flagella are not visible, the cells could easily be confused with the spindle-shaped cells of other genera.
Chlorogonium (Chlamydomonadaceae)
These videos show this species changing shape from circular to spindle and are not algae but PROTISTS!! - After observing with the 25x eyepiece instead of the usb camera - I noticed that there is definitely a split end that I can seen vibrating - meaning it HAS FLAGELLA.
Wikipedia says - https://en.wikipedia.org/wiki/Euglenid this about Euglena.
So at this stage I am waiting to see if the two samples I have in petri dishes come to fruition ...........then isolate and culture...JUST ALGAE, NO PROTISTS ALOWED!!!!
My Simple Square Box PhotoBioReactor PBR Design using recycled soda bottles
Then I designed a semi-circular PBR using an instructable and alot of guess work to build a semicircular shaped pbr and while it made removing and installing the tubes a little bit easier it was still too cumbersome and gangly to work with. Setting the lighting and air pump timers was a bitch. Also I dont think the tubes were close enough to the grow light.
THE main thing I was having trouble with was using the vertical tubes, each time.
The last straw with the tubes was when I noticed that despite the air stones at the bottom of the tubes I was getting SIGNIFICANT setting below the air stones at the bottom of the tubes.
Again not very practical. It was fun to build but just sucked.
I found that every time I took a sample it was in a 20 oz soda bottle and for some reason just adding a 100 ml of miracle gro algae media I created earlier the algae grew better than in the tubes.
So I decided to eliminate the tubes and just use recycled soda bottles and design a simple easy to change and clean and move things around in pbr. I know a run on sentence.
Here is the first square design made from nothing more than 2x4s - oh I had to buy the plexiglass but the 2x4s I alread had, from the previous leanto design.
This design was WAY easier to use and more practical. I decided to try putting the light underneath.
This didnt provide enough light so I redesigned it to be enclosed ( slightly more aesthetically pleasing - and lighting from the side of the bottles for better light penetration.
Here is what I came up with - definitely not my final design - designing is the fun part!!
All from a 4'X4' sheet of osb, I had it laying around.
screwed together with 2x2s
Placed the air pump and timers on top for easy access.
Two 4 gang controls in back.
Video of prettier design in operation - I used mirror tiles to try reflect light back up towards samples.
So the dark green sample, Second from the left is the sample I have been keeping going every since summer. I am still yet to get anything to grow inside my incubator so I have also placed 2 more samples of my summer sample to the far left.
TIME TO USE MY MICROSCOPE TO IDENTIFY WHICH ALGAE SPECIES ARE IN THE SAMPLE, AND WHICH IS THE DOMINANT. BUT I REALLY WANT MY COLONIES TO GROW SO I CAN ISOLATE ...........
