چکیده
Good sporulation was induced in batch culture using carbon sources that have in common the effect of reducing growth rate.

Sporulation of Clostridium thermosaccharolyticum under conditions of restricted growth.
Glucose served as an exogenous energy source for sporulation when a limited amount was fed continuously. Excess glucose repressed sporulation.
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 کاملPurification and properties of an amylopullulanase, a glucoamylase, and an alpha-glucosidase in the amylolytic enzyme system of Thermoanaerobacterium thermosaccharolyticum.
Thermoanaerobic bacteria are of considerable interest as producers of thermostable amylolytic enzymes. The soluble amylolytic enzyme system of Thermoanaerobacterium thermosaccharolyticum DSM 571 was fractionated into a pullulanase, a glucoamylase, and an alpha-glucosidase. The enzymes were purified to homogeneity and their physical and catalytic properties were studied. The pullulanase, which c...
متن کاملSporulation of Clostridium cylindrosporum on a Defined, Low-Manganese Medium.
Clostridium cylindrosporum HC-1 grew and sporulated well on a defined medium. This is the first demonstration of sporulation of a purinolytic clostridium on a defined medium; manganese levels were below those considered essential for sporulation of most Bacillus species. Sporulation appeared to be initiated before exhaustion of the purine substrate.
