Acid-Tolerant, Gram-Negative Bacteria Isolated From Montanan Coniferous Bed And Field Soil Samples

Abstract

Montanan field soil was found to have a pH of approximately 8.5 and coniferous bed soil a pH of approximately 7.0. From these soils, 10 Gram-negative bacilli were isolated by using selective, low pH media. The two soils yielded different isolates. Two isolates were identified as members of the family Enterobacteriaceae, probably of the genus Erwinia. The other isolates could not be identified.
