Effects of temperature and salinity on Vibrio cholerae growth.

摘要: Laboratory microecosystems (microcosms) prepared with a chemically defined sea salt solution were used to study effects of selected environmental parameters on growth and activity Vibrio cholerae. Growth responses under simulated estuarine conditions 10 strains V. cholerae, including clinical isolates as well serovars O1 non-O1, compared, all yielded populations approximately the same final size. Effects salinity temperature extended survival cholerae demonstrated that, at an (25%) degrees C, survived (i.e., was culturable) for less than 4 days. Salinity also found influence activity, measured by uptake 14C-amino acids. Studies effect ions that Na+ required growth. The results this further support status bacterium.
