Sporulation of Clostridium thermosaccharolyticum under conditions of restricted growth.
نویسندگان
چکیده
Glucose served as an exogenous energy source for sporulation when a limited amount was fed continuously. Excess glucose repressed sporulation.

Good sporulation was induced in batch culture using carbon sources that have in common the effect of reducing growth rate.
متن کاملInhibition of sporulation of Clostridium thermosaccharolyticum.
Studies were undertaken to determine the effect of chemical inhibitors on the sporulation of thermophilic anaerobes of which Clostridium thermosaccharolyticum is a representative organism. Since fluoroacetic acid (R. S. Hanson, Ph.D. Thesis, Univ. of Illinois, Urbana, 1962), diethyl malonate (6), and a-picolinic acid (pyridine-6-carboxylic acid; reference 3) have been found to inhibit the sporu...
متن کاملSporulation of the "thermophilic anaerobes".
A reasonable degree of synchrony in the sporulation of Clostridium thermosaccharolyticum 3814 was obtained by using three 10% transfers of 8-hr cultures in a medium containing 0.5% L-arabinose, 0.5% peptone, 0.5% yeast extract, and Gc minerals. Sporulation was stimulated by L-arabinose and L-xylose, but was repressed by glucose, mannose, fructose, and D-pentoses. Sporulating cells were long and...
متن کاملSporulation of Bacillus subtilis in continuous culture.
Sporulation of Bacillus subtilis 168 was studied in chemostat cultures. Sporulation occurred at high frequency under limitation of growth by glucose or the nitrogen source in minimal medium, whereas rates of sporulation were low for Mg(2+), phosphate, citrate, or tryptophan limitation. Sporulation was found at all growth rates tested, and the incidence of spores increased with decrease in growt...
