InterrelationshiP betwreen temperature and sodium chloride on growth of lactic acid bacteria isolated from meat-curing brines. J. Bacteriol. 85:1017-1021. 1963.-An elevation of the temperature limit for growth of some Pediococcus homari (Gaffkya homari) and motile Lactobacillus strains could be effected by the addition of sodium chloride to the growth medium. At the optimal temperature for growth, sodium-i chloride was stimulatory, and as the tem)erature of incubation was increased a mandatory requirement for sodium chloride was manifested. At the optimal temperature for growth (30 C), the highest sodium chloride concentrations were tolerated; as the temperature was increased, this tolerance decreased, although the ol)timal sodium chloride concentration increased. No other substances were found that would replace the sodium chloride requirement at higher temperatures of incubation. Individual bacterial species are often characterized by having specific minimal and maximal temperature limits of growth. These temperature limits are usually regarded as being rather constant characteristics of individual bacterial strains, although exceptions are known to occur. Little attention has been paid to the influence of the medium as it affects the teml)erature limits of growth.
