What is a cheap way to provide glucose/glycerol to cells?

Question

anonymous · Answer

By cheap do you mean 'energy efficient?' Because if so, I'd say that an energy efficient method would be to store it as fat, which is metabolized easier by cells than pure glycerol/glucose.

i mean, if i have a culture of algae and i wanna add glucose to it  (to enhance growth via their heterotrophic metabolic pathways), what would be a cheap (monetarily) way to do it?

anonymous · Answer

OH! monetarily. Well could you use a substitute? If so, diethylene glycol will serve the same purpose, but it's relatively cheaper. If you COULDN'T use a substitute... I would add starch to your culture, which degenerates into glucose. (If your starch was cold beforehand that would be even better -- if temperature wouldn't mess with your results.)
