what is a facultive anaerobe
anaerobic and aerobic respiration
what are electron acceptors in anaerobic respiration of e.coli
NO3 -> NO2 +43 FUMERATE -> SUCCINATE SO42- -> S2 NO42- -> NO FE3+ -> FE2+
desxribe the reduction nitrate reductase catalyses
contains molyvdoenzymes which reduces NO3- -> NO2-
formate D -> ubiq -> nitrate reductase NO3- -> NO2-
NADH D - meniquinole -> nitrate reducatase NO3- -> NO2-
what is zymonas mobilis
a g- facultive anaerobe which produces bioethanol, surpassing yeast
what does zymonas mobilis fo to glucose
degrades it to pyruvate and then ferments pyruvate to ethanol via alcoholic fermentation
what is mixed acid fermentation
anaerobic
charecteristic of enteric bacteria (intestinal)
with a varierty of producsts acrtase accetate succinate formate and ethanol and equal amounts co2 and h2o
what are the products of mixed acid fermentation
lactate acetate succinate formate and ethanol co2 and h2o
what illness can enteric bacteria cause
typhoid fever
gastroenteritis
bubonic plague
desribe the process of mixed acid fermentation
glucose -> pyruvate -> succinate/lactate/formic acid or acetyl coa
acetyl coa -> acetic acid or ethanol
formic acid -> co2 + h2
how do obligate anaerobes generate energy
from slp and etp -> 02
how do facultive anaerobes generate energy
etp>o2
slp etp_> no3- + fermentation
