Abstract

ABSTRACTFree ions of Na+, K+, Ca2+, and Mg2+influenced the optical density of planktonic cultures of thermophilic bacilli.Anoxybacillus flavithermusE16 andGeobacillussp. strain F75 (milk powder manufacturing plant isolates) andA. flavithermusDSM 2641 andG. thermoleovoransDSM 5366 were studied. Ca2+and Mg2+were associated with increases in optical density more so than Na+and K+. Overall, it appeared that Ca2+and/or Mg2+was required for the production of protein in thermophilic bacilli, as shown by results obtained withA. flavithermusE16, which was selected for further study.
