Effects of yeasts and bacteria on the levels of folates in rye sourdoughs.
The increase of folate content during fermentation was mainly due to folate synthesis by yeasts, and fermentation of non-sterilised flour-water mixtures resulted in three-fold increases in the folate contents.
Monoclonal antibodies against core and cellulose-binding domains of Trichoderma reesei cellobiohydrolases I and II and endoglucanase I.
Monoclonal antibodies can be specifically used to recognize and quantitate different domains of these three important cellulolytic enzymes from Trichoderma reesei.
Chromosomal polymorphism and adaptation to specific industrial environments of Saccharomyces strains
Abstract Several industrial Saccharomyces strains, including bakers', wine, brewers' and distillers' yeasts, have been characterized with regards to their DNA content, chromosomal polymorphism and
Growth efficiency of Saccharomyces cerevisiae on glucose/ethanol media with a smooth change in the dilution rate (A-stat)
Abstract The effects of the ethanol/glucose ratio on the growth characteristics ( μ max , Q O 2 max , Y XS , Y XO 2 , etc.) of Saccharomyces cerevisiae on mineral media were studied. The maximum
Genetic homology between Saccharomyces cerevisiae and its sibling species S. paradoxus and S. bayanus: Electrophoretic karyotypes
Chromosomal DNAs of many monosporic strains of the biological species Saccharomyces cerevisiae, S. paradoxus and S. bayanus were analysed using contour‐clamped homogeneous electric field electrophgoresis and a comparative study of Ty1, Ty2 and telomere‐associated Y' sequences having multiple chromosomal location was done.
Chromosomal reorganization during meiosis of Saccharomyces cerevisiae baker's yeasts
The genomic constitution of two S. cerevisiae baker's yeasts and their meiotic products have been analyzed by pulsed-field gel-electrophoresis, hybridization with specific gene probes, marker segregation, and flow cytometry, showing chromosomal patterns substantially different from those of laboratory strains used as controls.
Production of folate by bacteria isolated from oat bran.
Folate vitamer distribution was determined for eight bacteria including one isolated from rye flakes and marked differences in the distribution of folate vitamers among the bacterial strains were revealed by the HPLC analysis.
Polymeric SUC genes in natural populations of Saccharomyces cerevisiae.
The accumulation of SUC genes was observed in populations derived from sources containing sucrose and seems to be absent in strains from sources promoting the MEL gene.
In situ enrichment of folate by microorganisms in beta-glucan rich oat and barley matrices.
Study of folate production of yeast strains, bacteria isolated from oat bran, and selected lactic acid bacteria as well as one propionibacterium in oat and barley based models aimed at sustaining the stability of viscosity, representing the physicochemical state of beta-glucan.
Production of folate in oat bran fermentation by yeasts isolated from barley and diverse foods
The focus of the research was to identify yeasts from barley kernels in order to study their folate production capability while maintaining high viscosity caused by soluble fibres in oat bran
