Effect of water activities of heating and recovery media on apparent heat resistance of Bacillus cereus spores
Article Abstract:
Research indicates that contemporary calculations of the protective effect of water activity decreases on bacteria are overestimated, drawing on data obtained from spores of Bacillus cereus that were recovered after heating. Water activity's overall effect was reduced in response to added depressors, such as sucrose, glucose, and glycerol.

Two-step freezing procedure for cryopreservation of rumen ciliates, an effective tool for creation of a frozen rumen protozoa bank
Article Abstract:
Research demonstrates that a two-step procedure consisting of a holding temperature of -30 C, a cooling rate fromice nucleation temperature to holding temperature of between 1.2 C/min and 2.5 C/min, and using rumen juice as the thawing medium significantly improves the survival rate for rumen protozoa.

Effect of organic complex compounds on Bacillus thermoamylovorans growth and glucose fermentation
Article Abstract:
Research was conducted to examine the effect of a mixture of yeast extract and bioTrypcase (YE+bT) on the growth and physiology of lactic acid producing bacteria. Results show that YE+bT increased lactic acid yield and also influenced the ratio between cellular synthesis and energy production.
