Selecting yeast for industrial distilleries.

Variable flocculation profiles of yeast strains isolated from cachaça distilleries.

In cachaça production, the use of yeast cells as starters with predictable flocculation behavior facilitates the cell recovery at the end of each fermentation cycle. Therefore, the aim of this work was to explain the behavior of cachaça yeast strains in fermentation vats containing sugarcane through the determination of biochemical and molecular parameters associated with flocculation phenotype...

Microbial Transglutaminases investigations for selecting putative forms of industrial interest

Beta-lactamase reporter system for selecting high-producing yeast clones.

In modern production of protein biopharmaceuticals, a good screening and selection method of high-producing clones can dramatically influence the whole production process and lead to lower production costs. We have created a rapid, simple, and inexpensive method for selecting high-producing clones in the yeast Pichia pastoris that is based on the beta-lactamase reporter system. By integrating t...

Marine yeast isolation and industrial application

Over the last century, terrestrial yeasts have been widely used in various industries, such as baking, brewing, wine, bioethanol and pharmaceutical protein production. However, only little attention has been given to marine yeasts. Recent research showed that marine yeasts have several unique and promising features over the terrestrial yeasts, for example higher osmosis tolerance, higher specia...

Classic Techniques for Improvement of Industrial Yeast Strains

The enucleation of yeast cells is of interest for the production (by fusion) of special industrial yeast hybrids, possessing mixed cytoplasms (cybrids) but only one nucleus. Such cybrids could be designed to have a modified phenotype without change of ploidy. However, no methods for the enucleation of yeast cells have yet been reported. In animal cells, enucleation usually uses the cytochalasin...
