Survival of Lyophilized Bacillus popilliae in Soil¹

^a Division of Biology, Kansas State University, Manhattan, Kansas 66502

ABSTRACT

Survival of lyophilized vegetative Bacillus popilliae in dry soil and in soil kept in atmospheres with different relative humidities (RH) was determined. Cells survived for at least 1 year when the RH was 22% or lower, but an RH of 33% or higher reduced viability. At 33% RH, no bacteria were recovered after 5 months of storage; at 42% or above, no bacteria were recovered after 1 month of storage.
