Changes in the carbohydrate composition of cytosol from fungal spores in connection with environmental temperature and during storage

Abstract: Differences in the carbohydrate composition were revealed among spores of fungi belonging to Zygomycetes, Ascomycota, Basidiomycota, and Oomycota, part of the novel kingdom Chromista. It was shown for the first time that Phytophthora infestans contains arabitol in addition to glucose and trehalose. Sucrose was detected in Pleurotus ostreatus basidiospores. It was established that Blakeslea trispora stylospores contain inositol. The dependence of the spore carbohydrate composition on the temperature of the habitat of the corresponding species is discussed. It was shown that the cytosol of the conidia is dominated by trehalose and inositol under hypothermic conditions and by mannitol and glucose under hyperthermic conditions. Neomycota and Eomycota were shown to differ in their responses to stress (starvation), which correlated with the differences in the carbohydrate composition of the spore cytosols. Assuming that cytosol carbohydrates perform a protective function, we explain the higher viability of conidia compared to stylo- and sporangiospores.

Method of xylitol producing

Abstract: FIELD: genetic engineering, microbiological industry, biotechnology. SUBSTANCE: yeasts or fungi producing arabitol are transformed with DNA encoding D-arabitol dehydrogenase forming D-xylose and DNA encoding xylitol dehydrogenase. Then transformed yeasts or fungi are cultured under conditions providing the synthesis of xylitol and xylitol is isolated. Yeasts are taken among Zygosaccharomyces rouxii, Candida polymorpha, Torulopsis candida, Pichia farinosa, Torulaspora hansenii. Fungi are taken among Dendryphiella salina and Schizophyllum commune. Method ensures to convert easily available carbon sources, for example, D-glucose to xylitol. EFFECT: improved method of producing. 21 cl, 13 dwg, 7 tbl, 15 ex

Method for simultaneous rapid detection of various sugars, sugar alcohols and alcohols in beer

Abstract: The invention discloses a method for simultaneous rapid detection of various sugars, sugar alcohols and alcohols in beer, belonging to the technical field of analytical chemistry. In the method provided by the invention, an integrated pulsed amperometric-ion chromatography is used, by optimization of a pretreatment detection method, experimental factors influencing separation of constituents are researched, and a method for simultaneously detecting 23 types of sugars, sugar alcohols and alcohols (2, 3-butanediol, ethyl alcohol, methanol, glycerin, erythritol, xylitol, fucose, arabitol, sorbitol, trehalose, ribovitol, mannitol, 2-DNA-D-glucose, mannose, melibiose, glucose, maltitol, fructose, lactose, ribose, sucrose, raffinose and maltitol ) in the beer is built one time. Thus, a technicalproblem of accurate analysis on multiple constituents including the sugars, the sugar alcohols and the alcohols in the beer is solved, the method provided by the invention is rapid, accurate and sensitive, realizes simultaneous analysis of multiple types and multiple constituents, and makes an important contribution to detection of beer constituents.
