Algae Definition and 24 Threads

Summary:: Not looking for concrete answers, just want to spitball some ideas about the basics of Algae cultivation and implications of scaling to large scale. So the idea is this: Build massive ponds and seed them with an initial culture of algae. Wait one doubling period and filter out half...

I'm just devastated by the news of climate change as of late, and I knew it was worrying but I've never been more worried about it in my life than I am right now. Have we truly passed the point of no return? Are we all doomed? Or do we still have time? Is algae carbon capture the way out? And...

There was/is a recent report of red snow in Antartica, Ukranian Research station Verdnasky which got me interested. I had never heard of this phenomenom before. While some colored snow can be attributed to mineral content, this particular red snow is biological in origin. Apparantly reports go...

AIUI, there are these 3 types of algae, with blue-green algae being technically bacteria, green algae being plants, but what are red algae?

Does anyone know how algae take in nutrients? Is it by diffusion or active transport?

I am a Newbie to the biology forum. Have 43 years of experience in applied microbiology and biochemical engineering

Does algae fall under the plant kingdom or thr protista kingdom? Why does blue-green algae fall under thr kingdom monera if it is a kind of algae? Thanks for any help in advance!

Could anyone tell me that what is the name of the unicellular green algae which acts as an indicators of clean water. Actually I am solving a crossword puzzle so I need assist in one question the hint to this specific algae is that it is an 7 letters long word and its second letter is E.

Hi! I'm doing a worksheet on Body Size, Heat Loss and SA/Vol Ratio. The question I'm confused by is: "The smallest organisms such as bacteria, protozoa and unicellular algae live in water or a saturated atmosphere. They are only found in dry situations as cysts or spores. Why?" The wording...

Since algae can produce oxygen in closed containers, which you can inhale as a byproduct, when provided CO2 from your lungs; you could in theory take diving cylinders filled with algae with you, when diving, correct? I suppose this hasn't been done before, why not?

[SIZE="5"]How do we fix this? The green scum shown in this image is the worst algae bloom Lake Erie has experienced in decades. Such blooms were common in the lake’s shallow western basin in the 1950s and 60s. Phosphorus from farms, sewage, and industry fertilized the waters so that huge...

Hi, I am doing this science fair thing and for it I've decided to power something using biofuel from algae. I have everything i need to grow algae but I am not sure how to get from algae to biofuel. Could someone please tell me or suggest a website about how this process works. It would also...

Homework Statement I just translated this word problem: The zone of a alga increases every 2 month about the factor 4. How many days does the alga needs to increse into the double? How many days ago has the alga been the half? Homework Equations The Attempt at a Solution...

A number of strains of microalgae are known to produce relatively high yields of energy as fuel stock [pre-biodiesel] in the form of plant oils, as a function of area and time - typically as BTU/acre-year, or MJ/hectare-day, etc. From a review of the literature, it is my perception that...

Just wondering how does algae get into my pool? Is it transported through insects from other bodies of water or something else??

How do I treat a goldfish pond green with algae? Visibility is ~2 inches. It's not the wall coating I'm concerned about, it's the water itself. I know how I'd treat it indoors - with a scraper and a water change, but that won't work in a pond. (Well, I suppose a water change would help...)...

I have read the ASP ( Aquatic Species Program) report about growing Algae and have it processed to be used as a feedstock for Biodiesel . Given that 60% of the body mass of algea is usable oil as compared to only 15% at best from any land grown plant source. My question is what process can...

anyone here know how does oxidizers kill off those algae?i know that oxygen atoms are produced but am not sure the mechanism that cause the death of the algae. also how do flocculants actually work in clumping the algae together?

what is the relationship between Algae and pH value? why there are more algae ,pH value rises?

anyone here know how algaecides control algae growth?specificity? any other methods on controlling algae growth would b greatly appreciated

Can guppys, a alage eater, and a albanio cory tolerate salt in their water?

Does anyone know where I could find some research on the rate at which nitrogen fixation occurs in blue green algae? Im looking for some sort of formula to calculate the amount of fixed nitrogen produced by a certain amount of blue green algae. Hopeing someone has seen something somewhere on...
