Oh god, they're so pretty. And small. Mmm. Algae.


The Algae Reddit

Algae - a very large and diverse group of eukaryotic organisms, ranging from unicellular genera such as Chlorella and the diatoms to multicellular forms such as the giant kelp, a large brown alga that may grow up to 50 meters in length. Most are autotrophic and lack many of the distinct cell and tissue types found in land plants such as stomata, xylem and phloem. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of algae that includes Spirogyra and the stoneworts.

There is no generally accepted definition of algae. One definition is that algae "have chlorophyll as their primary photosynthetic pigment and lack a sterile covering of cells around their reproductive cells". Other authors exclude all prokaryotes[4] and thus do not consider cyanobacteria (blue-green algae) as algae.

Where to get Live Spirulina Cultures??

Hi Guys, I'm working on a Photobioreactor in NYC for my Senior project and I think I messed up the ratios in my growing medium for my Spirulina, so I'm struggling to figure out where to get more Live culture here in the US. Does anyone know anyone in NY or nearby who is willing to donate or sell me some?

I'm now a proud owner of a marimo moss ball :)

The setup is temporary, she'll live in a bigger bowl with rocks but i think she's adorable as is :)

Microalgae isn't growing in my liquid media. Has anyone else encountered this issue?

Hello everyone, I am a master's student who has recently developed an interest in microalgae, and I would like to ask for your advice regarding an issue I am facing.

My Chlamydomonas reinhardtii strain CC-4414 is growing abnormally in TAP (Tris-Acetate-Phosphate) medium, cultured in a shaker at 125 rpm, incubated at 25°C under limited light (dark) conditions with a 12:12 hr light/dark cycle. The picture I showed is of C. reinhardtii incubated for 7 days. Has anyone ever encountered this problem before?

Make sure to check for Algae in water

Algae presence in water no joke, and honestly, with all the stuff you hear about contaminated water, it’s hard not to worry...I started thinking about how to keep my family safer at home, so I picked up an electric water filter that handles over 30 contaminants...I’m going to also invest in a really good water testing kit to see what’s actually in the drinking water.

I need help

Does anyone know how you preserve this kind of algae? I need them to stay flexible and not rot for two weeks. I have them in a plastic bag now with just a bit splash water. Do you have any experience or ideas? Thank you!

Breeding

I’m an oyster farmer/algae technician. we’ve been buying starter cultures that have been good, but i am curious on how to breed my algae. from what i’ve gathered it’s a series of dilutions until you can isolate the single cells. there was other information about pheromones and nitrates and i would like to know more about manipulating those factors. any input would be appreciated thank you.

Algae bloom?

Our little lake has had some pretty serious algae overgrowth, despite tegular treatment by a water management company . Last week the water maintenance company confirmed that its Lyngbya. They proposed a treatment with phycomycin, said it “might work” , but usually “it goes away on its own” ? The internet says that it’s usually pretty difficult to treat and may never go away.. has anyone had experience with this? We live in Michigan, during winter, there is a lot of cloud coverage and this lake almost completely freezes over and gets covered with snow.. 🤔

Chlorella

Hello, I need help choosing the best Chlorella from 2 different manufacturers (for selling to others).

  1. EU manufacture.

Pros: Their chlorella is grown indoors (heterotrophic cultivated) so it doesn't have any heavy metals.

Cons: The tablets are small, so it may be inconvenient to take 6-12 a day (250mg per tablet). Also, they are less potent because they contain less nutrition and chlorophyll (there is no sun when growing)—Chlorophyll per 100 grams is only 488 mg.

See full label here

  1. Taiwan manufacture

Pros: Bigger tablets (400 mg). More nutrition, more chlorophyll compared to the EU (because it's grown outdoors and gets direct sun) - Chlorophyll >2000 mg/100g.

Cons: Possibility of heavy metals because it's grown outdoors. Also, more expensive.

See full label here

What would you recommend? I want the most effective Chlorella with lots of chlorophyll so it helps detox the body better, improve immunity and so on. But I also don't want to have any possibility of heavy metals.

chlorella vulgaris algae cultutre in india ............NEEDED!!!!!!!!!!!

Hello, I am an engineering student interested in working on a project related to algae. Specifically, I require the algae Chlorella vulgaris culture for this project. I have attempted to find it online without success, and the local dealers and manufacturers I've contacted so far only sell extracts or powder. If you have any details or information about a seller, manufacturer or any labs who can provide me with a culture of Chlorella vulgaris, please mention it below to assist me.

Can someone help identify this algae for me?

I found this light purple algae growing in my lake a couple of days ago. I have not been able to identify it but I go swimming with my dog and just want to be safe in case this algae is toxic. Thanks!

I live in Washington if that helps.

Algae blooms making my water gross?

Anyone else freaking out about the algae blooms affecting our water? It's gross...I’m seriously considering getting a reverse osmosis water filter just to make sure there’s ZERO algae residue at all. Apparently the algae can either get into the drinking water or it also produces toxins that can get into the water, and there’s more and more growing from the warmer temperatures/global warming. I even found this article from the CDC talking about the issue and what they’re doing to prevent it from affecting drinking water. Idk I just want to safe, would a RO filter be overkill?

Algae ID

Hi guys, a question arose among my laboratory friends about what this algae would be.

I thought it could be a cyanobacteria but even fungus was considered.
