Utilization of baker's yeast (Saccharomyces cerevisiae) for the production of yeast extract: Effects of different enzymatic treatments on solid, protein and carbohydrate recovery / Primena pekarskog kvasca (Saccharomyces cerevisiae) za dobijanje kvaščevih ekstrakata - uticaj različitih parametara enzimske hidrolize na sadržaj suve materije, proteina i ugljenih hidrata
(Serbian Chemical Society, Belgrade, 2007)
Yeast extract (YE) was produced from commercial pressed baker's yeast (active and inactivated) using two enzymes: papain and lyticase. The effects of enzyme concentration and hydrolysis time on the recovery of solid, protein ...
Models of interactions of laser beams with materials of interest for optical components and provoked damages
(Polish Academy of Sciences, 2007)
Models of interactions of laser beams with materials of interest for optical components are presented in this paper. Special attention is paid to damages which appear within both active materials and optical components ...
A linear solvation energy relationship study for the reactivity of 2-substituted cyclohex-1-enecarboxylic and 2-substituted benzoic acids with diazodiphenylmethane in aprotic and protic solvents / Proučavanje reaktivnosti 2-supstituisanih cikloheks-1- -enkarboksilnih i 2-supstituisanih benzoevih kiselina u aprotičnim i protičnim rastvaračima pomoću linearne korelacije solvatacionih energija
(Serbian Chemical Society, Belgrade, 2007)
The rate constants for the reaction of 2-substituted cyclohex-1-enecarboxylic acids and the corresponding 2-substituted benzoic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 ºC. In order ...
