GC-MS-Based Metabolomics Study of Single- and Dual-Species Biofilms of Candida albicans and Klebsiella pneumoniae.

Abstract: Candida albicans and Klebsiella pneumoniae frequently co-exist within the human host as a complex biofilm community. These pathogens are of interest because their association is also related to significantly increased morbidity and mortality in hospitalized patients. With the aim of highlighting metabolic shifts occurring in the dual-species biofilm, an untargeted GC-MS-based metabolomics approach was applied to single and mixed biofilms of C. albicans and K. pneumoniae. Metabolomic results showed that among the extracellular metabolites identified, approximately 40 compounds had significantly changed relative abundance, mainly involving central carbon, amino acid, vitamin, and secondary metabolisms, such as serine, leucine, arabitol, phosphate, vitamin B6, cyclo-(Phe-Pro), trehalose, and nicotinic acid. The results were related to the strict interactions between the two species and the different microbial composition in the early and mature biofilms.

Isotopic studies of carbohydrate metabolism during basidiospore germination inSchizophyllum commune

Abstract: Uptake and respiration of radioactive glucose, mannitol and arabitol were studied during basidiospore germination of the woodrotting mushroomSchizophyllum commune. Glucose uptake was rapid and immediate, depressed at 4° C and unaffected by the protein synthesis antagonist cycloheximide. In contrast, uptake of either mannitol or arabitol exhibited a lag phase while the induction of this process was sensitive to cycloheximide. Prior incubation of basidiospores in unlabelled mannitol induced uptake processes for either labelled mannitol or arabitol. Respiratory rates for either arabitol or mannitol increased markedly upon germination in glucose-asparagine minimal culture medium.

Enzyme preparations in liquid form

Abstract: Stable aqueous solutions of enzymes of microbiological origin, e.g. amylase or protease, and at least 50% by weight of a sugar alcohol, e.g. sorbitol, mannitol, dulcitol or arabitol, a sugar, e.g. glucose, xylose, mannose, fructose, sorbose or sucrose, or glycerol.
