DESCRIPTION OF SERPENTINIMONAS MACCRORYI SP. NOV.

Serpentinimonas maccroryi (mac.cro′ ry.i. N.L. gen. n. maccroryi , named after D. McCrory, one of the owners of The Cedars nature reserve).

In addition to the characteristics given above in the genus description, the type strain has the characteristics described below. Growth occurs at 18–37°C and pH 9.0–12.5 with optimal growth at 30 °C and pH 11.0. The strain tolerates NaCl ranges from 0 to 0.5 g l−1. The DNA G+C composition of the type strain is 66.7mol% (determined from the genome). The strain grows autotrophically on formate and hydrogen gas but not on thiosulfate under microaerophilic conditions. The strain can use nitrate, but not thiosulfate as an electron acceptor. The strain can ferment glucose and grow heterotrophically on acetate, butyrate, lactate, pyruvate, ethanol, glucose and fumarate. Major fatty acids are C 16:0, C 16:1 ω7 c and C 18:1 ω7 c. The respiratory quinone is ubiquinone.

The type strain, B1 T (=NBRC 111850 T =DSM 103919 T), was isolated from a highly alkaline serpentinizing spring (Barnes Spring 1) in The Cedars located in north California, USA.
