โœฆ Synopsis

original cultures showed an acid production for about 10 hours to a minimum pH of about 6.7, after which there was an abrupt rise in pH to over 8 5 . The cellobiose-positive variants from these cultures reduced the pH of the medium to a value around 5.5 in 20 hours. Frequently the acid production was so great that the organisms were killed.

The results of this investigation indicate the fcrmentation of a given substance, such as cellobiose, is not necessarily a constant characteristic.

The temperature profile of growth and death rates of a strain of Kluyveromyces marxianus var. marxianus was found to be essentially dissociative, with an optimum temperature for growth at around 38 "C and sustained exponential growth up to 43-44 "C. At temperatures near the maximum temperature for g
