Nisin is a bacteriocin produced by many strains of Lactococcus lactis. This study examined the effect of nisin on Mycobacterium smegmatis, a non-pathogenic species of Mycobacterium. Nisin had a minimum inhibitory concentration of 8.0 micrograms ml-1

Listeria monocytogenes isolates resistant to 10(5) IU ml-1 nisin were obtained at 30 degrees C (NR30) and at 10 degrees C (NR10). Nisin prolonged the lag phase of isolate NR30 at 10 degrees C. Isolates NR30 and NR10 did not produce a nisinase. Protop

The metabiotic effect of Bacillus licheniformis on Clostridium botulinum was examined. B. licheniformis elevated the pH of a model system with an initial pH of 4.4 so that C. botulinum grew and produced toxin. Toxin production was observed when spore

Clostridium botulinum B-aphis spores plated on medium containing 4% salt at pH 6.0 yielded colonies at a frequency of ca. 1 in 10(6). A subculture of one of these colonies, designated strain Ba410, was compared with the parent strain, B-aphis, for a

Clostridium botulinum 62A growth rates declined with decreasing pH and increasing salt levels. Lysis rates, however, were affected only by pH. Due to competition between growth and lysis rates, an accurate assessment of interactive effects was obtain

Plating efficiencies of Clostridium botulinum 62A spores on media with variable pH (7.0 to 5.5) and salt (0, 1, 2, and 3%) levels revealed that only a very small subpopulation could give rise to colonies. The relative size of this subpopulation decre

Reports that Clostridium botulinum toxin can sometimes be detected in the absence of indicators of overt spoilage led to a systematic study of this phenomenon in a model system. Media with various combinations of pH (5.0 to 7.0) and glucose (0.0 to 1
