I have been having this doubt for quite some time. Major companies like ExxonMobil have withdrawn their funding for algal biofuels. Recently, even the researches published focus more on using algae as alternative protein sources rather than biofuels. Is it the end of algal biofuel era?

In my free time, I run a YouTube channel that's primarily focused on sustainable science and tech research, with a long term goal of developing systems in various areas that enable the decentralised, sustainable abundance, of many things we use and interact with every day.

At present, one of my key interests is the cultivation of Algae, and it's use in the production of biofuels. I started out growing Spirulina, but soon found out that extracting lipids from it wasn't so easy, due to the cell structure.

My recent endeavours have involved the cultivation of Chlorella instead, which is meant to have a much higher lipid content, and those lipids are meant to be easier to extract.

I'm all for further discussion here, and hope we can collaborate in some way.

Found in norcal intertidal zone. Thanks!!

Hi everyone, can you help me with ID, please, is this a haematoccous cell?

I’m doing an experiment to determine the effect of salinity on algae growth. I am using water from a saltwater aquarium. Do I need to put algae in each sample, or can I just put water samples under a grow light? On a related note, do I need to put some kind of extra food in the samples, or will it grow on its own?

I want to create a couple of recipes for these but don't know which would be the best

Very curious as to why more human snack foods don't have more algae in them. Its nutritious, rich in protein and vitamins? Why not just sprinkle it on some stuff and make it taste good and look fun? Have you guys have any good algae food snacks.

Hello, I am a BE undergrad student . I need some information for the production of algaes . Basically

a) The type of nutrients solutions need for the growth ?

b) we are using both the ways from raw algae and algae powder comparing the costs and lipid concentration.

If anyone having expertise in the field . Please give advice or suggest some better ways sto increase efficiency...

Hello everyone! I have a question regarding the photosynthesis rate in algae, even better if you know for pondweed. Specifically, does anyone have data or insights on the average photosynthesis rate (measured in µmol O₂/cm²s) across different wavelengths of light (400-700 nm)? Additionally, if anyone knows the general average photosynthesis rate for pondweed or algae, that information would also be very helpful. Thank you!

This black algae has been growing on the sand in my tank. I looked at a sample under a microscope and see these small round cells that clump together, can anyone ID? I’d like to know what they are so I can figure out how to get rid of them. Also just curious what these large brown things are. More images in comments. Thanks

Can succulent plant feed help grow algae?

We have a small wildlife pond with some aquatic plants in our front garden. Recently we've had some algae growing and was wondering what type it was.

The brown algae was what I was most interested in. I'm guessing it's beneficial and benign but thought I would find out. Covers about 1/3 of surface, and we'll be taking efforts to stop it growing over too fast.

I found this green like matted filamentous substance that produces a lot of bubbles I’ve never seen before in my hornwort grow out tub and it’s outcompeting my hornwort and enveloping it, I took some out and separated in a smaller container just see better what it is and it’s light green and a bit yellowish, and wondering if it’s Cyanobacteria because it’s spooky how fast it’s growing
