Reproduced from SciFinder, with permission from the Chemical Abstracts Service. Incubation of S. typhimurium and Y. pseudotuberculosis in 30% petroleum ether at 37° inhibited respiration more than did 0.01-0.03% Na lauryl sulfate [151-21-3]. After a 72-h incubation in 10% glycerol [56-81-5] the respiration level returned to, or approached normal. Petroleum ether also inhibited dehydrogenase [9035-82-9] activity and glycolysis more than did Na lauryl sulfate. Incubation in glycerol also reversed this inhibition. Na lauryl sulfate completely and irreversibly inhibited phosphatase [9013-05-2] at pH 5.4 and 8.0. Petroleum ether inhibited phosphatase at pH 5.4 in Y. pseudotuberculosis and at pH 8.0 in S. typhimurium.
