  Under nutrient deficient conditions , Biochemical studies have also suggested that acetyl-CoA carboxylase (ACCase), a biotin-containing enzyme that catalyzes an early step in fatty acid biosynthesis, may be involved in the control of this lipid accumulation process.

  5 g dry algal biomass - grind with 5 ml methanol using mortal and pestle then add 75 ml (2:1) chlorofm:methnl...centrifg it..collect the solvnt. repeat the step 3 to 5 times...compain all the solvent add 25% of water from the total solvnt......phase wll separt (within half hour) collect the chlorom layer(lower)..dry it (fully)...weigh the dry lipid material...... calcultin = obtaind lipid weight /taken biomass x 100........ u can get the total lipid...... u need only nonpolar lipid just use hexane thats it.....all d bset

Narsi wants to know Why isn't the world becoming fully vegetarian? 5 months ago

All right, you could say I take a high moral ground while asking this question, but there it is.

I am a strict vegetarian by choice, and my preference is guided primarily by ethics ("killing animals when they don't harm us is wrong"). But I am here not to discuss the ethics of vegetarianism (which I will be glad to discuss on My Desk), but the sustainability of being vegetarian.

Apart from the obvious greenhouse gases increase owing to the large number of cattle population because of non-vegetarianism, there could be other aspects that hinder a progress to sustainable world.

So, being vegetarian is not only ethical but also makes the world more sustainable. So, why isn't the world not turning vegetarian? Is it because they cannot control their taste buds? That sounds like such a crime!

What are your thoughts?

  There is nothing wrong with killing animals to feed ourselves, because this is what they are created for. Our bodies need vegetables as well as meats.

Mesho wants to know microalgae and metal ions 6 months ago

Hi there, what is the metal ion which have toxic effect on microalgae? or what is the heavy metals that affecting algal growth?

  Generally the order of metal toxicity which affects the algal species is Hg> Cu>Cd>Ag>Pb>Zn. Mercury being the most toxic metal affects the enzyme systems of the algae and inhibits their functions. Copper is used to control the algal blooms in fresh water. The extent of toxicity depends on the ionic content or free Cu2+ ions available in the algal culture and not the total copper concentration.
