Glucose catabolism during germination of Bacillus megaterium spores.
نویسندگان
چکیده
When heat-activated spores of Bacillus megaterium germinated in glucose-containing medium, 10 to 30% of the glucose was found to be oxidized to gluconate.

Activation energy for glucose-induced germination of Bacillus megaterium spores.
The maximum germination rate of Bacillus megaterium QM B1551 spores in glucose increased, and the lag before its attainment decreased, with increasing germination temperature. The activation energy for germination (mu = approximately 20 kcal/mole), based on rate or on lag, was consistent with an enzymatic mechanism.

متن کاملGermination of Bacillus megaterium spores after various extraction procedures.
The initiation of germination of Bacillus megaterium QM B1551 spores, grown in supplemented nutrient broth, has been studied. The initiation properties depend on buffer concentrations and the particular batch of spores. Initiation in l-alanine, KBr, calcium dipicolinate, or in buffer alone increases as a function of the spore age; whereas initiation in glucose, l-leucine, or l-proline remains r...
متن کاملThe GerW Protein Is Not Involved in the Germination of Spores of Bacillus Species
Germination of dormant spores of Bacillus species is initiated when nutrient germinants bind to germinant receptors in spores' inner membrane and this interaction triggers the release of dipicolinic acid and cations from the spore core and their replacement by water. Bacillus subtilis spores contain three functional germinant receptors encoded by the gerA, gerB, and gerK operons. The GerA germi...
متن کاملMetabolic requirements for microcycle sporogenesis of Bacillus megaterium.
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 thus produced were heat-stable and required heat activation for germination. The original amount of spore deoxyribonucleic acid tripled before completion of the cycle. Acetate and a small amount of a...
