I bought a 500ml bottle of phytoplankton it says it's green and brown culture, I'm making a 1liter tank for them ready how much salt needed and I don't have a fertilizer for them what can I do to help them?

Hello everyone, I am finishing undergrad now and am looking at grad schools to pursue research in phycology. I have not fully narrowed down exactly what I want to focus on during post grad, but think I want to focus HABs. Is anyone here involved in anything or know of good schools or researchers to reach out to?

Hi,
Im a beginner in algae and want to grow some for the first time. My teacher said spirulina would be a good first choice. I found a growing kit online with food for the algea for growing 2 liters of algae water. I'm wondering what I should give them when I don't have any food left.
Can I buy some somewhere?

I hope someone can help me :) any tips are welcome.

I'd appreciate your aid 🙏 What is this?

Found in Santa Barbara, California

Hi there. I am wondering if anyone can tell me what is happening in this picture. These two algae look like conjugating a bit but they are probably not the same species. Or maybe they are and the darker one is just infested with something? It grows some short tentacle-like thingies at its end.

Hello. What is this balloon-looking structure growing from or attached to this filamentous algae?

Location: Rio de La Plata, Buenos Aires, Argentina.

This is in Mill Creek in Dexter MI all over the rocks. Is it Didymo? Thanks in advance!

I would like to talk to some folks about perceived issues in open autotrophic systems -- things like light penetration, photoinhibition, their technoeconomic impacts, etc.

Does anyone sell Raw Living Chlorella or any other forms or “Raw Living” Algae?

Also, this site (https://www.rawlivingspirulina.com/faq-support-center/) claims that Raw Living Spirulina is a little bit better nutritionally than Raw Living Chlorella. However, i’ve read online that supposedly Chlorella is slightly better nutritionally and Spirulina is only better in the protein category or something. Which is the truth?

They also claim on the site that powder and pill form of Algae is only 2-3% bioavailable in comparison to Living Algae, which would be over 95% bioavailable. Is the difference really that significant? Wouldn’t this make the powder and pill forms almost pointless to purchase as well as dried seaweeds?

What are these green grain-like algae? If they even are algae, that is. We have some large plastic tanks sitting out with water in the sun and there's just this layer of green dots floating on it.

(I find it incredibly stupid that you can only post one picture because I would have provided more for a better idea. What is even the point?)

Hi everyone,

I'm recreating a small photobioreactor ( Raspberry Pi based Photobioreactor (youtube.com) ) to monitor the growth of microalgae. Due the the nature of ordering parts, I'm going to end up with enough to build a few of these.

If anyone is interested in making one of these, reach out as I will have quite a few extra parts.

Cheers!

Along with a light source and co2 will a NPK solution be sufficient for chlorella growth? And if a simple NPK is not a sufficient growing media for chlorella what would be an easily obtained inexpensive source?

Looking for some ID help on this blob with the beans inside of it. I know it isn't the best quality photo, but any help would be fantastic. It is about 14um long

Could anyone assist in identifying these white-ish dots? I don't know if it's algae, but is looks like it. Grew on the glass as well.

Good day all, sucks that I can only send 1 picture, anyhow I'll explain what it looks like dissected.

Cutting into it reveals a gelatinous inside, similar to a trifle, it starts as a dark green that then shades into a red that then morfs into a brown(all within the span of a cm) then it morphs into green through to its stem(between 5-8 cm thick), I say stem because it looks like what I cut off was the stem, last biology class I did was in grade 9 so I'm clueless here😂

It's environment is one the final salt evaporation dams, but it doesn't extend into the last dam (I read recently that halophiles/halophytes can't stand salt water that hits near 30%+ salinity so I imagine this is why)these last dams do tend to be between 25-60% saline before we put them into the pans(depends on which line of dams we are talking about)

Now you ask why I want to know? Well it seems to be that these growths are slowing our evaporation in these dams(providing shade for water underneath) what I am trying to find out is if they have any purposes beyond cooling these dams down? if I could sustainably cultivate and harvest this I would rather do that then the other option being diverting the water to other dams, sun baking the dams in question and then scraping them clean, if you need another picture or 2 just ask, thx

I am culturing nannochloropsis and a random fresh water algae in identical bottles with a led plant light and an airline in both bottles, a very basic set up to feed brine shrimp.

The bottles are next to each other, although I make sure I use separate equipment for each culture, is it likely one of the cultures could contaminate the other one?

Hi everyone,

I'm currently working on my bachelor's thesis focusing on the fermentation of macroalgae and biogas production, and I'd greatly appreciate some guidance on a few specific aspects of my research. Here are the key points I'm seeking advice on:

1. Theoretical Framework: I'm in the process of conducting a theoretical overview of macroalgae fermentation. Can anyone recommend essential literature or provide insights into fundamental concepts and methodologies related to this topic?
2. Review of Prior Work: I'm interested in understanding previous studies on macroalgae fermentation, including methodologies employed and potential research gaps. Any suggestions on how to approach this review effectively?
3. Measurement Methods: I'm looking for recommendations on reliable methods for measuring key parameters during macroalgae fermentation. Any suggestions or experiences with specific techniques would be incredibly helpful.
4. Utilization of Enzymes and Bacterial Strains: I'm exploring the potential use of enzymes from sea urchins and bacterial strains from the gut in my fermentation process. Can anyone point me towards relevant studies or provide advice on isolating and utilizing these components effectively?
5. Materials and Methods: What are the typical materials, media, bacteria strains, and enzymes used in macroalgae fermentation? Any insights or recommendations on selecting appropriate materials for my experiments?
6. Industrial Fermentation Techniques: I'm curious about the methods employed by biogas producers in fermenting organic matter. Are there any parallels or lessons learned from their processes that could be applied to fermenting macroalgae?

When it comes to my pre-existing knowledge there isn't alot to go on, therefore i come to you for some advice and learning. Any advice, resources, or personal experiences related to these topics would be immensely valuable to me as I progress with my thesis. Thank you in advance for your help!

I’m currently working on trying to plan out the required volume for a system, but I’m running into an information bottleneck.

I’m looking at designing/building a closed system with a Cyanobacteria colony to offset the CO2 put off by the occupant(s). From what I can find, something along the lines of azollae or spirulina would work, but I can’t find how sequester rates compare to that of typical adult human respiration.

If anyone knows of specific studies that would be a good reference I would appreciate being pointed in the right direction.

Thanks

This may be a long shot, but might anyone know how to get a free version of this book?

I am trying to grow algae in a small bottle of salt water.

The purpose is to create a live food source for my sea monkeys.

I am following the instructions in this video:

https://youtu.be/gTRl8cu7jlc?si=G_xO5FOFYTqe1yMr&t=234

At 3:54, he shows the food source. But you need both bottles and they cost $20 each.

Is there something similar I could use that's cheap? I noticed there's also seachem flourish, but it's not specific to algae but it has some of similar nutrients.
