Biotechnological potential of red yeast isolated from birch forests in Poland
Objectives
This study aimed to isolate red yeast from sap, bark and slime exudates collected from Polish birch forests and then assessment of their biotechnological potential.
Results
24 strains of red yeast were isolated from the bark, sap and spring slime fluxes of birch (Betula pendula). Strains belonging to Rhodotorula mucilaginosa (6), Rhodosporidiobolus colostri (4), Cystrofilobasidium capitaum (3), Phaffia rhodozyma (3) and Cystobasidium psychroaquaticum (3) were dominant. The highest efficiency of carotenoid biosynthesis (5.04 mg L−1) was obtained by R. mucilaginosa CMIFS 004, while lipids were most efficiently produced by two strains of P. rhodozyma (5.40 and 5.33 g L−1). The highest amount of exopolysaccharides (3.75 g L−1) was produced by the R. glutinis CMIFS 103. Eleven strains showed lipolytic activity, nine amylolytic activity, and only two proteolytic activity. The presence of biosurfactants was not found. The growth of most species of pathogenic moulds was best inhibited by Rhodotorula yeasts.
Conclusion
Silver birch is a good natural source for the isolation of new strains of red yeast with wide biotechnological potential.
期刊介绍：
Biotechnology Letters is the world’s leading rapid-publication primary journal dedicated to biotechnology as a whole – that is to topics relating to actual or potential applications of biological reactions affected by microbial, plant or animal cells and biocatalysts derived from them.
All relevant aspects of molecular biology, genetics and cell biochemistry, of process and reactor design, of pre- and post-treatment steps, and of manufacturing or service operations are therefore included.
Contributions from industrial and academic laboratories are equally welcome. We also welcome contributions covering biotechnological aspects of regenerative medicine and biomaterials and also cancer biotechnology. Criteria for the acceptance of papers relate to our aim of publishing useful and informative results that will be of value to other workers in related fields.
The emphasis is very much on novelty and immediacy in order to justify rapid publication of authors’ results. It should be noted, however, that we do not normally publish papers (but this is not absolute) that deal with unidentified consortia of microorganisms (e.g. as in activated sludge) as these results may not be easily reproducible in other laboratories.
Papers describing the isolation and identification of microorganisms are not regarded as appropriate but such information can be appended as supporting information to a paper. Papers dealing with simple process development are usually considered to lack sufficient novelty or interest to warrant publication.
