Lactobacilli
Xeno Biology

Terran Bacteria 

Lactobacilli are rod-shaped, Gram-positive, fermentative, facultative anaerobic or microaerophilic organotrophs. Normally they form straight rods but under certain conditions spiral or coccobacillary forms have been observed. In most cases they form chains of varying length. Lactobacilli belong to the lactic acid bacteria and comprise the major part of this group. As their name implies, they produce lactic acid and derive energy from the fermentation of lactose, glucose and other sugars to lactate via homofermentative metabolism. About 85-90% of the sugar utilized in the fermentative process is converted to lactic acid. However, there are some heterofermentative lactobacilli that produce alcohol in addition to lactic acid from sugars. This acid-producing mechanism inhibits growth of other organisms and favours the growth of lactobacilli that thrive in low pH environments. ATP is generated during the process by non-oxidative substrate-level phoshorylation. -

According to the US National Institutes of Health, lactobacillus is:
