What are these bumps on Rehydrated Chondrus Crispus?

Dried Wildcrafted Chondrus Crispus(Irish Seamus) White/Clear Bumps on sea moss spread sporadically. No present on all leaves. Two or 3 reddish/pinkish bumps. Approximately 0.039-0.1135in (1-2 mm) in diameter.

They seem embed or strongly attached when I cut a couple off. They are only present on some leaves not all.

Do I need to through away my whole bag of sea moss?

I’ve been told on another sub that they are gametes, papillae, and/or sporing body.

Also I suspect that this is not Chondrus Crispus because of the bumps but a variety of some Mastocarpus still edible?

hello guys we are currentlly working on a project where we use diatoms as indicator of water quality for river, now i need some help regarding the process of after getting the water samples with diatoms, how can we preserve them for laboratory identifcation and counting and what chemicals we can use to preserve them and the entire process we should do after obtaining the samples

I found this chunk of "algae" growing in a concrete bowl on a pillar of a fountain at downtown Zamboanga City, Philippines. Do any of you here know what it is?

I have a feeling that this is a freshwater sponge in a symbiotic relationship with algae, as it did not feel slimy to the touch, just fuzzy, but I don't know if sponge larvae can be carried by rain or if it was cultivated there somehow.

I’ve been experimenting with these Beaker Bags for growing algae, and they’ve been a great way to demonstrate photosynthesis and carbon fixation in a simple, controlled setup. Perfect for small-scale experiments or teaching labs!

Anyone else using similar systems to grow algae? Would love to hear how you’re using them or share ideas for projects!

Curious if this could be cultivated at home for use as a dietary supplement. Would it be feasible and/or safe?

(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 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!

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?

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.

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.

A complete Pediastrum duplex!

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.
