Another mystery "algae" that is actually a heterotrophic nanoflagellate.

Look at this little alien!

Nutrition in plants is the component that is necessary for living organisms to survive. It compromises elements...

Course in Reed College explains Dinoflagellates' bioluminescent behaviour

Course in Reed College explains Dinoflagellates’ bioluminescent behaviour

Bioluminescence is a phenomenon in which an organism produces and emits light. This ability can be seen in wide range of disparate organisms, the most common example being the firefly. Our focus is on the bioluminescent behavior of dinoflagellates. Dinoflagellates are sometimes called  “Pyrrohophyta,” meaning ‘fire plants’ because of some species’ ability to chemically produce light (5).

Omega-3 Insights Magazine: Algal-Based Omega-3s

Beyond dietary intake, the consumption of fish oil products was the go-to omega-3 source for many years. Alternatives such as krill and flaxseed oil entered the market, but left a void for vegetarians or those seeking long-chain omegas. Algal oil fills that void, providing eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), depending on the source. Although the market is in the early…

ABSTRACT: Cyanobacteria are a dominant structural component of N2-fixing microbial mats in diverse marine ecosystems. As a result, much of the measured N2 fixation activity has been attributed to the cyanobacterial component. Until recently, the contribution of heterotrophic N2 fixers has received much less attention. In this study, the presence, diversity, and ubiquity of heterotrophic N2 fixers were investigated in 3 cyanobacteria (Microcoleus)-dominated, intertidal microbial mats obtained from Tomales Bay, California, Sippewissett Salt Marsh, Massachusetts, and Bird Shoal, North Carolina. Using PCR techniques, a diverse array of heretofore uncharacterized heterotrophic nifH (gene encoding the Fe-protein subunit of nitrogenase) sequences were found in these geographically disparate microbial mats, suggesting that heterotrophic diazotrophs may play a larger role in N2 fixation dynamics than previously thought. Phylogenetically similar heterotrophic diazotrophic sequences were obtained from the 3 sites, potentially indicating that similar heterotrophic N2-fixing communities are responsible for this process at diverse locations.

Nutrition Info

Alrighty, so as a bacteria, you can imagine that I don't exactly eat the same way that you humans do. So that's what I'm going to talk about now!

First of all, I'm what's called a heterotrophic organism. That basically just means that I get my food from an outside source (outside of me, that is). In my case, I get my food from my host organism (which in this case, is you!). I absorb carbon through something called biosynthesis, using the organic molecules that I get from my host organism. Carbon is basically my favourite thing, because I need it to survive. My very existence is composed largely of carbon molecules that hold important stuff together- but you don't need to know that. 

That's everything you need to know about what I eat, so. Yep. :D
