Hello

bonjour est il possible de transformer un sucre et un phosphate (solide) en acide lactique grace aux bacteries lactiques"lactobacillus bulgaricus" et "steptococcus thermophilus"???
si oui..pouvez vous me dire comment faire cela??
merci

OK, this is the probably the wrong category for my question, but here it is anyway. I'm running an experiment where I grow a culture to exponential phase while shaking (very aerobic). Than I treat the culture and put it in an incubator with no shaking. How long would it take for the cells go into anaerobic respiration? I realize there are several unknown factors here, so a ballpark answer would be just fine.

Thanks

So basically I just want to know the fundamental differences between these two and why you would use one vs the other. I've tried looking in papers and manufacturer sites and noone says WHY they use one or the other, they just do it. Thanks!!!
