We have studied systematically the effect of the non-ionic surfactants Thesit and Triton X-100, and of propan-2-ol (used as a substrate solubilizer) on the activity of the cholesterol oxidases from Streptomyces hygroscopicus (SCO) and Brevibacterium sterolicum (BCO). Low concentrations of Thesit lead to an activity increase with both enzymes; at higher surfactant concentrations the opposite eff...

In order to determine the factors of decay and sourness fig fruits, in summer 2016-17, 60 leaf, fruit stem samples from different regions Tehran, Varamin (Qal'e No), Mazandaran (Amol, Noor Sari), Lorestan Iran a branch sample Italy were collected.
