Isolation, identification and characterization of regional indigenous Saccharomyces cerevisiae strains
(Elsevier, 2016-01-27)In the present work we isolated and identified various indigenous Saccharomyces cerevisiae strains and screened them for the selected oenological properties. These S. cerevisiae strains were isolated from berries and ... -
Accumulation of Poly(3-hydroxybutyrate) Helps Bacterial Cells to Survive Freezing
(PLoS, 2016-06-17)Accumulation of polyhydroxybutyrate (PHB) seems to be a common metabolic strategy adopted by many bacteria to cope with cold environments. This work aimed at evaluating and understanding the cryoprotective effect of PHB. ... -
Optimization of Enzymatic Hydrolysis of Waste Bread before Fermentation
(Mendel University Press, 2017-02-28)Finding of optimal hydrolysis conditions is important for increasing the yield of saccharides. The higher yield of saccharides is usable for increase of the following fermentation effectivity. In this study optimal conditions ... -
Pilot-scale production of poly--hydroxybutyrate with the cyanobacterium Synechocytis sp. CCALA192 in a non-sterile tubular photobioreactor
(Elsevier, 2018-07-20)The biopolymer poly--hydroxybutyrate (PHB) can be used as a promising bioplastic. It has a broad range of applications and is degraded relatively rapidly by soil organisms. Like many prokaryotes, the cyanobacterium ... -
The use of fractionated Kraft lignin to improve the mechanical and biological properties of PVA-based scaffolds
(The Royal Society of Chemistry, 2019-04-23)The mechanical properties of poly(vinyl alcohol) (PVA)-based scaffolds were successfully improved. The improvements in mechanical properties correlated with the amount of Kraft lignin in PVA matrices. The critical property ... -
Fusarium Mycotoxins Stability during the Malting and Brewing Processes
