Characterization and Expression of β-1,3-Glucanase Genes in Jujube Fruit Induced by the Microbial Biocontrol Agent Cryptococcus laurentii

Influence of Oxidative Stress on Biocontrol Activity of Cryptococcus laurentii against Blue Mold on Peach Fruit

The limitations of chemical fungicides for the control of postharvest diseases have recently become more apparent. The utilization of antagonistic microorganisms is a promising alternative to that of fungicides to control postharvest decay. In previous studies, the antagonistic yeast Cryptococcus laurentii has shown excellent effects of biocontrol and great potential for practical application. ...

Xylosyltransferases in Cryptococcus laurentii.

Heteroglycan synthesis in Cryptococcus laurentii.

An enzyme preparation from Cryptococcus laurentii catalyzes the transfer of glycosyl units from sugar nucleotides to exogenous acceptor resulting in the stepwise synthesis of a heteroglycan with the following structure: Z-O-a-n-mannosyl6-O-oc-D-mannosyl-3-~-~-D-mannosyl-(2 -0 -0 -D -xylosyl-) D-mannose. The same enzyme preparation transfers D-[‘T]mannosyl from GDP [WJmannose to an endogenous gl...

Mannosyl transfer in Cryptococcus laurentii.

A particle-bound enzyme from the fungus imperfectus Cryfitococcus taurentii var. flavescens (NRRL Y-1401) mediates transfer of mannosyl units from GDP-mannose to endogenous primer. The enzyme requires divalent cations for activity. The pH optimum is ‘7.5 and the apparent K, for GDP-mannose is 0.14 mbr. A polysaccharide fraction that is associated with the enzyme was found to be similar to a pol...
