Outgrowth of Bacillus megaterium Spores in the Presence of Nitrate and Ammonium Ions

Distribution and Correlation of Events During Thermal Inactivation of Bacillus megaterium Spores1
Levinson, Hillel S., Hyatt, Mildred T.
Aqueous suspensions of Bacillus megaterium QM B1551 spores were heated at temperatures from 75 to 85 C. The rapid initial viability loss, followed by a more gradual, almost exponential decline, was...
Activation Energy for Glucose-Induced Germination of Bacillus megaterium Spores
Levinson, Hillel S., Hyatt, Mildred T.

Metabolic Requirements for Microcycle Sporogenesis of Bacillus megaterium1
Holmes, P. K., Levinson, Hillel S.
Spores of Bacillus megaterium QM B1551 germinated, elongated, and resporulated (microcycle sporogenesis) in simple chemically defined media which permitted no cell division. The second-stage spores...

Ultrathin sections were prepared from cultures of Bacillus megaterium QM B1551 undergoing microcycle sporogenesis (initial spore to primary cell to second-stage spore without intervening cell...
Water Vapor, Aqueous Ethyl Alcohol, and Heat Activation of Bacillus megaterium Spore Germination1
Hyatt, Mildred T., Levinson, Hillel S.
Dormant spores of Bacillus megaterium were activated for germination on glucose by heating them in aqueous suspension (but not if heated dry), by treating them with aqueous ethyl alcohol at 30 C, or...
