Genus species Oceanobacillus iheyensis HTE831
Description and significance
Oceanobacillus ihyeeynsis HTE831 is an extremely haolotolerant and alkaliphilic Bacillus related species. It is isolated from deep sea sediment collected at a depth of 1050m on the Iheya Ridge. This strain is Gram positive, rod-shaped, aerobic, and spore forming. It is motile by the use of peritrichous flagella. Isolate HTE831 grows from a pH range of 6.5-9.5 and in 0-21% NaCl. The salinities were 0-21% in NaCl at pH 7.5 and 0-18% NaCl at pH 9.5.
Genome structure
The genome of O.iheyensis is a single circular chromosome consisting of 3,630,528 nt. The entire genome sequence for O. iheyenes has been determined in Japan MSTC sequencing center. There are 3594 genes and 3500 are protein coding with 92 structural RNAs. The genome has 3496 ORFs with 1972 assigned functions. Six kinds of new insertion sequences (ISs), IS667 to IS672, a group II intron (Oi.Int), and an incomplete transposon (Tn852loi) were identified in O. iheyenes.
