Scanning electron micrograph of Streptococcus bovis JB1 by Ahmed Hetta

Introduction

Streptococcus bovis JB1 was isolated from a cow fed alfalfa hay in Davis, CA, USA[1]. It is a major amylolytic bacterium that depolymerize starch to glucose, fermenting it to large amounts of lactic acid that can lead to lactic acidosis in ruminants.

DefenseFinder Results

Methylome

No methylation motifs were detected in Streptococcus bovis JB1.

Methylating E. coli Strains

No E. coli methylation strain has been constructed for S. bovis JB1 strain

Culturing Conditions

Streptococcus bovis JB1 grows on both M2GSC and SDM (Semi Defined medium). Cells grow overnight at 37 °C in SDM or M2GSC culture medium with head space composed of 95% CO2 and 5% H2. Similarly, Streptococcus bovis JB1 grows overnight on SDM agar plates. Agar plates were placed in anaerobic Jar and incubated in anaerobic chamber under gas mixture that is composed of 95% CO2 and 5% H2.
