Microbial Glycosylation of Flavonoids

Sandra Sordon/ Jarosław Popłoński/ Ewa Huszcza

Flavonoids constitute a large group of polyphenolic compounds naturally found in plants, which have a wide range of biological activity. Although flavonoids are beneficial to human health, their application is limited by their low bioavailability and poor water-solubility. Therefore, recently there has been a particular interest in glycosylated forms of flavonoids, which usually are better soluble, more stable, and more functional compared to their aglycones. Microbial transformation of natural (..)

Enzymes Involved in Naproxen Degradation by Planococcus sp. S5

Danuta Wojcieszyńska/ Dorota Domaradzka/ Katarzyna Hupert-Kocurek/ Urszula Guzik

Naproxen is a one of the most popular non-steroidal anti-inflammatory drugs (NSAIDs) entering the environment as a result of high consumption. For this reason, there is an emerging need to recognize mechanisms of its degradation and enzymes engaged in this process. Planococcus sp. S5 is a gram positive strain able to degrade naproxen in monosubstrate culture (27%). However, naproxen is not a suf­ficient growth substrate for this strain. In the presence of benzoate, 4-hydroxybenzoic acid, 3,4-dih(..)

Characterization of Bacteria Isolation of Bacteria from Pinyon Rhizosphere, Producing Biosurfactants from Agro-Industrial Waste

Arnoldo Wong-Villarreal/ Lizbeth Reyes-López/ Hipólito Corzo González/ Cristina Blanco González/ Gustavo Yáñez-Ocampo

Two hundred and fifty bacterial strains were isolated from pinyon rhizosphere and screened for biosurfactants production. Among them, six bacterial strains were selected for their potential to produce biosurfactants using two low cost wastes, crude glycerol and lactoserum, as raw material. Both wastes were useful for producing biosurfactants because of their high content in fat and carbohydrates. The six strains were identified by 16S rDNA with an identity percentage higher than 95%, three strai(..)
