MODELING AND OPTIMIZATION OF BAKERY YEAST (SACCHAROMYCES CEREVISIAE) VIABILITY BY USING EXPERIMENTAL DESIGN PROCEDURE
Journal Title: Journal of Engineering Studies and Research - Year 2017, Vol 23, Issue 3
Abstract
This paper presents the application of kn experiment design procedure for simulation and optimization of growth capacity for baker’s yeast, Saccharomyces cerevisiae. There were performed 27 experiments according to the experimental design procedure. The input variables were: the amount of carbohydrates (X1), temperature (X2) and pH (X3) and the output variable was the autolyzed cells (Y). The optimal conditions for growth parameters of Saccharomyces cerevisiae were obtained for an amount of carbohydrates (glucose) of 46.8 g·L-1, a temperature of 30oC and a pH of 5.7.
CARBOXYLATO ADDUCTS AND DERIVATIVES CONTAINING SnR3 (R = Ph, Me) AND SnMe2 RESIDUES: SYNTHESIS, INFRARED AND MÖSSBAUER STUDIES
Twelve new carboxylato adducts and derivatives containing SnR3 (R = Ph, Me) and SnMe2 residues have been synthesized and characterized by elemental analyses, infrared and 119Sn-Mossbauer spectroscopies. The proposed stru...
