Streptococcus ruminicola is a species of Gram-positive, facultatively anaerobic, non-motile bacteria in the genus Streptococcus within the family Streptococcaceae. It was first isolated from the rumen fluid of Hanwoo cattle in South Korea and described as a novel species in 2022.[1][2]
Etymology
[edit]The name ruminicola is derived from Latin: rumen (gen. ruminis), meaning the first stomach of ruminants, and -cola, meaning dweller or inhabitant. Thus, ruminicola means “inhabitant of the rumen.”[1][2]
Morphology and physiology
[edit]S. ruminicola cells are Gram-positive, non-motile cocci that are negative for both oxidase and catalase. They grow under facultatively anaerobic conditions, with optimal growth at 37 °C on brain heart infusion agar. Growth occurs at temperatures from 20–45 °C, pH 6–9 (optimum 6.5–7.0), and in up to 6.5% NaCl (w/v).[1]
