Streptococcus equinus B315
Introduction
Streptococcus equinus B315
Streptococcus equinus B315 was isolated from bovine rumen contents in NZ [1]. B315 is proteolytic, Gram positive, and able to ferment a wide range of carbohydrates. Its main fermentation product is lactate, together with succinate and acetate [1]. The B315 genome encodes two lantibiotic bacteriocin biosynthetic gene clusters.
The draft genome for B315 (1,786,673 bp) was generated through the Hungate1000 project with JGI [2].
NCBI: Streptococcus equinus.
GTDB: Streptococcus equinus. B315 belongs to the same species group as the S. equinus type strain (DSM 20558).
Risk group: 2.

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.
