Relationship between sublethal injury and inactivation of yeast cells by the combination of sorbic acid and pulsed electric fields

Article Abstract:

A study was conducted to investigate the occurrence of sublethal injury after the pulsed electric field (PEF) treatment of yeast cells and the effect of combination of PEF and sorbic acid. It was found that PEF caused sublethal injury in both yeasts Dekeera bruxellensis and Saccharomyces cervisiae and combination of PEF and sorbic acid achieved higher level of yeast inactivation.

Adaptation of the yeast URA3 selection system to gram-negative bacteria and generation of a deltabetCDE Pseudomonas putida strain

Article Abstract:

A general procedure for efficient generation of gene knockouts in gram-negative bacteria by the adaptation of the Saccharomyces cerevisiae URA3 selection system is described. A Psuedomonas putida strain lacking the URA homolog pyrF was constructed, allowing the use of a plasmid-borne copy of the gene as the target of selection.

Abundant and diverse fungal microbiota in the murine intestine

Article Abstract:

A study was conducted on the variety of roles played by enteric microbiota in intestinal health and disease. It was observed that the presence of diverse fungal taxa in the intestinal microbial community in abundance play significant roles in enteric microbial functions.
