The effect of different protectants and the impact of the initial cell density on the viability of Lactococcus lactis Sr. 3.54 subjected to freeze-thawing and freezedrying was studied. Several additives were tested as protective agents against freezing and drying injuries. Maximum viability of the cells after freeze-thawing was obtained with sucrose and skim milk mixtures as protective agents (...

To analyse the role of trehalose as stress protectant and carbon storage compound in the grey mould fungus Botrytis cinerea, mutants defective in trehalose-6-phosphate synthase (TPS1) and neutral trehalase (TRE1) were constructed. The Deltatps1 mutant was unable to synthesize trehalose, whereas the Deltatre1 mutant showed elevated trehalose levels compared to the wild-type and was unable to mob...

Myocytes power the movement of all organs in body. Damage to and degradation myocytes causes hypokinesia muscle-related degenerative diseases. Apigenin, a kind flavone, is being used treat many disorders. It exerts host different pharmacological activities, such as anti-inflammatory, anti-mutagenic, cardioprotective, antioxidant effects. Accordingly, apigenin considered promising candidate for ...
