(The lamelle is broken and the camera is ehh but id say its still beautiful)

My first thought was it was chlorela, but I never really tried to identify algae, so it can be anything that is just small green round cell and I wouldn’t know. Anyone please chip in either your ideas 🙏🏻

Btw I took this sample from the jar where I was growing spirulina or so I thought

Nitrogenase is very sensitive to oxygen existence inside the cell, thus heterocysts (for instance in Nostocales) get hydrocarbones from other cells, which produce it through photosynthesis, and then use it in pentose phosphate pathway. Other cells of these organisms get oxygen as a by-product. Oxygenic photosyntesis and nitrogen fixation cannot occur in the same cell. But Oscillatoriales don't have cell differentiation. How do they live?

Found in Red Rock Canyon National Conservation Area in Nevada. Super bright green algae like thing on surface of water. I didn’t edit the color at all, it’s just that green. Very stringy with some bubbles here and there.

Im doing this work for uni that is like a thought in which we re going to modify it genetically so that it expresses carboxyssomes from S elongatus.It doesnt really have to work but we are having lots of trouble finding a backbone vector for it. Is there even one?

This is Ethel. I have had her for many years, although she has only been living outside for 3 or four years.

I just noticed she seems to be growing something green on her belly. I am in the US, we are in the middle of winter.

I'm curious what type of algae would grow on a rust covered metal surface in the middle of winter?

I'm not too concerned, because I think if we have freezing temperatures, or after the sun comes out in the summer, it will go dormant. But if I wanted to try to control or kill it, just curious what people would use?

Thanks in advance for any information!

Hi everyone, I have a spiruline culture and I´ve watch another microalgae, maybe chlorella ... Can I eliminated "chlorella" from spiruline culture with some technique or reactive? Thanks!

I'm really interested in algae and I want to start growing them by myself in a glass tank. I've heard about Ulva lacuta ,Caulerpalentillifera, Eisenia bicyclis or Schizochytrium. But I don't know where to start, I want to do it as a hobby to use them in the kitchen. Can anyone help me out?

I'm wondering if anyone here is also involved in algae cultivation at a professional level. I'm going to Seagriculture in March. Maybe we can get in touch!

A while ago, I posted a picture of my chlorella vulgaris culture. Here I have some microscope pictures:

Hi,

I'm new here and hopefully I'm in the correct sub-reddit to have my qns answered.

I have a freshwater aquarium, glass wall but I'm not sure how to grow algae on the walls. It's in direct/ indirect sunlight , with shrimps and snails and some java moss / red rooters / water lettuces.

Just whar am I missing to have a full glass of green algae growing on it? Or is there any products that can promote wall algae ?

Hi everyone, there is a risk of contamination if I use glucose as a carbon source in open ponds? Thanks

Hello guys, I have a couple very basic questions but don't mind me since i'm extremely new to the topic. I have 6 liters of Basal Bold Medium and Chlorella Vulgaris in the exact amount for 6l of BBM. My question is do i need to dissolve BBM in water in order to put the algae in it, or do i just put it in this as it is? What is the exact procedure for creating a diy home photobioreactor? I'm very interested in this topic and I'm very happy i could get my hands on some algae and BBM easily but i have no idea what to do and the articles and research papers i've so far read have done nothing but confused me additionaly.

A complete Pediastrum duplex!

In the Unknown section, I need help with some IDs. Observe, iNat, Google images do not do well differentiating between similar appearing microscopic organisms. https://sixie6e.github.io/unknown.html Also, if you find errors in the Plantae section, I would humbly appreciate the corrections.

It’s in a salt water sea monkey tank on a window sill. It was seeded from my sea monkey aquarium but that algae is just a solid sheet of green and has no patterns.

Hello everyone, I‘m trying to cultivate Chlorella Vulgaris algae to investigate it‘s ability to bind CO₂ . To the question: I wonder what the bubbles, as you can see in the picture, mean for the health of the algae culture. Does anyone have an idea or can give me advice? Thanks in advance Cheers

Could any one confirm this is nannochloropsis

Anyone have any ideas on this? It looks like a diatom to me but beyond that I haven't figured it out. Thank you so much in advance!

Hello!

Hope you can help me with this, im seeking a medium for culturing freshwater dinoflagellates, most specific Ceratium hirundinella. Does anyone have some expierence in this species or some recipe i can borrow???

Thanks a lot!!

So I have an aerogarden growlight, that I stopped using for growing grow pods but instead for providente light for my other plants. Doing so has left algae to grow in the water not being used by any plants. I've become interested in seeing how much can grow in there, so I've considered leaving the water open to the light and adding a little plant food to encourage growth. I am researching algae and have come across the toxicity of Cyanobacteria. My question is if keeping this in my bedroom will damage my health somehow. Could this produce enough toxic things into the air that my health, my plants health, or my Bearded Dragon's health could suffer for it?

Edit: I’ve scrapped the idea and dumped the algae but I’m still curious about the answer to this question

The Aerogarden in question, this question is not about the health of my plants T-T
