Specific Growth Rates

The specific growth rates of one strain each of Ruminoccoccus flavefaciens, R. albus, Bacteroides succinogenes and Clostridium polysaccharolyticum were measured at a constant pH value in a pH-auxostat continuous culture system, using ball-milled filter paper cellulose as limiting substrate. By manipulating the buffer capacity of the medium, the degree to which the substrate was utilized before fresh medium was dosed to the cultures was controlled. With all four species, the specific growth rates declines as the cultures were forced to utilize the more refractory (crystalline?) portion of the substrate, but the species differed in the steepness of this decline. (Graphs of specific growth rates versus degree of solubilization of cellulose will be presented.) These dissimilarities in behavior are probably a reflection of differences between the species in the complements of cellulases at their disposal.

Antibody Technique

Chromobacterium lividum and a Pseudomonas sp. were grown in pure and mixed continuous culture with and without the clay-mineral, kaolinite. Irrespective of the growth conditions, C. lividum adhered to the wall of the culture vessel whereas the Pseudomonas sp. showed no such tendency, at least visually. During mixed culture studies, the organism which was initially established in the culture dominated. The ratio between C. lividum and the Pseudomonas sp. was about 20:1 when C. lividum was first established and 1:2 when the Pseudomonas sp. was first grown. The indirect fluorescent antibody technique provided a rapid method for differentiating the mixed cultures when the bacterial concentration was sufficient for microscopic analysis. During both pure and mixed continuous culture studies, the addition of kaolinite reduced the C. lividum but not the Pseudomonas sp. population.
