Query: NC_014724:59000 Lactobacillus amylovorus GRL 1112 chromosome, complete genome
Lineage: Lactobacillus amylovorus; Lactobacillus; Lactobacillaceae; Lactobacillales; Firmicutes; Bacteria
General Information: Lactobacillus amylovorus GRL 1112 strain has been isolated from porcine faeces. This strain is also of interest as a putative probiotic. Lactobacillus amylovorus is a common member of the normal gastrointestinal tract microbiota in pigs, and specific strains have been suggested as potential probiotics. In addition, Lactobacillus amylovorus has also been isolated from plant material.
Subject: NC_007426:205390 Natronomonas pharaonis DSM 2160, complete genome
Lineage: Natronomonas pharaonis; Natronomonas; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea
General Information: Isolated from Lake Gabara in Egypt. Extreme haloalkaliphilic archeon. Natronomonas pharaonis is able to survive at high salt and pH conditions which results in limited nitrogen availability through ammonium. In order to compensate for this, Natronomonas pharaonis has developed three systems to promote nitrogen assimilation: direct uptake of ammonia, uptake of nitrate, and uptake of urea. Another problem with high pH environments is the use of a proton gradient for the generation of ATP, which other alkaliphiles have adapted to by substitution of sodium ions for protons. However, this organism utilizes protons for ATP generation as determined by experimental data.
