Arthrobacter globiformis and Its Bacteriophage in Soil

By L. E. Casida and Kang-Chien Liu

Abstract

Bacteriophages in soil for Arthrobacter globiformis were rarely detected unless the soil was nutritionally amended and incubated. In amended soil, phage were continuously produced for at least 48 h, and this did not require the addition of host cells. Rod and spheroid stage host cells added to the amended soil encountered indigenous bacteriophage, but added phage did not encounter sensitive indigenous host cells for some time, if at all. The indigenous phage in nonincubated soil seemed to be present in a masked state which was not merely a loose physical adsorption to soil materials but required growth conditions other than lysogeny for them to increase their titers. The possibility is discussed that the indigenous host cells in nonamended soil are present in a nonsensitive spheroid state, with the cells becoming sensitive to the phage in a rate-limiting fashion as nonsynchronous outgrowth occurs for a portion of the spheroid cells
