Attachment of the yeast Rhodosporidium toruloides is mediated by adhesives localized at sites of bud cell development

Article Abstract:

Research was conducted to examine the adhesion of the basidiomycetous yeast Rhodosporidium toruloides to plant surfaces. Nonadherent fungal mutants were obtained after chemical mutagenesis with methane-sulfonic acid ethyl ester. Enzyme, lectin and chemical treatments revealed that the polar regions consisted of alkali-soluble materials. Results indicate that compounds localized at sites of bud development mediate the adhesion of R. toruloides to both barley leaf and polysterene surfaces.

Role of cystathionine [beta]-lyase in catabolism of amino acids to sulfur volatiles by genetic variants of Lactobacillus helveticus CNRZ 32

Article Abstract:

The role and mechanism of cystathionine [beta]-lyase (CBL) in the production of volatile sulfur compounds (VSCs) from sulfur-containing amino acids/derivatives, namely, methionine, cysteine and cystathionine which was determined by using the genetic variants of Lactobacillus helveticus CNRZ 32 is described.
