Sporulation of Clostridium thermosaccharolyticum.
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 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 کاملSome requirements of biological nitrogen fixation.
Clues to the mechanism of biological nitrogen fixation have been sought through experiments aimed at defining the substances specifically required by organisms to effect the process. The nitrogen-fixing sequence in bacteria is known to proceed through ammonia (Zelitch et al., 1951; Newton et al., 1953; Wilson and Burris, 1953; Virtanen, 1953). Thus, the effect of adding ammonium salts to a fixi...
متن کاملStudies on the Nitrogen Requirements of Some Ruminal Cellulolytic Bacteria.
Knowledge of the nitrogen compounds utilized for growth of ruminal cellulolytic bacteria is of considerable importance to an understanding of the nitrogen economy of ruminants and of factors affecting ruminal cellulose digestion. Work with mixed cultures of bacteria from the rumen has shown that cellulose digestion occurs with ammonia or urea, which rapidly yields ammonia, as the sole source of...
