    Strains producing β-glucosidase were isolated by solid medium containing esculin and ferric.Then six strains having high β-glucosidase activity were selected with p-nitropheny l-β-D-glucopyranoside as substrate.Strain having high ginsenoside bioconversion was finally chosen with Rbl as substrate and converted products were determined by TLC and HPLC.β-glucosidase activity of this strain was 0.803 U/mL and ginsenoside Rd conversation rate was 97.234 2%.The selected strain was identified as Saccharomycopsisfibuligera based on the morphology and nucleotide sequence analysis of the 18S rDNA.Fermentation medium was optimized to contain lactose as carbon source and corn flour as nitrogen source,and Ca2+ as metal ion.Finally inducer was optimized to promote the ginsenoside bioconversion.Results indicated that inducer had little impact on the bioconversion but rutin,a kind of inducer,could promote the bioconversion of Rd to CK.The selected strain with high ginsenoside bioconversion had good potential application.

    Single-factor experiment and response surface methodology were used to optimize the ultrasonic-assisted aqueous two-phase extraction of polysaccharides from Potentilla anserina L. Four key factors including ethanol concentration, ammonium sulfate concentration, solid-liquid ratio and ultrasonic power were selected by one-factor-at-a-time experiments. The optimum conditions of ultrasonic-assisted aqueous two-phase extraction of polysaccharides from Potentilla anserina L. were as follows: Ultrasonic power at 240 W with 31% ethanol volume and 19% ammonium sulfate, the extraction yield of polysaccharides from Potentilla anserina L. reached (9.035±0.119)%. Infrared spectrum analysis confirmed that the extracts were polysaccharides. Potentilla anserina polysaccharide was composed of rhamnose, mannose, glucose and galactose, with the molar ratio of 1.00∶1.69∶10.61∶2.66. The in vitro activity results showed that the antioxidant activity of polysaccharides extracted by ultrasonic-assisted two-phase extraction was better than that of traditional water extraction. Ultrasonic assisted aqueous two-phase technology was a reliable and efficient method for polysaccharide extraction.

    研究了分别用HCl和乳酸调节培养基初始pH以及在发酵过程中加入不同的酸中和剂对乳酸菌生长和乳酸产量的影响.结果表明,终产物乳酸的积累是抑制乳酸菌生长和导致乳酸产量下降的直接原因,该情况随发酵液中H+浓度的升高(即pH的降低)而增强,H+的积累对菌体生长和产酸的影响是间接的;用CaCO3调节发酵液pH优于用NaOH和NH4OH.

    Microbial food cultures are important resources of the traditional fermented food industry.In this review,the references related to functional strains from Chinese traditional fermented foods such as dairy,baijiu,tea,soy sauce,vinegar,sufu and pickle were gathered and analyzed.The scientific criteria for evaluation of microbial food cultures were summarized.The first inventory of microbial species used in Chinese traditional fermented foods was proposed,which contained 30 genera and 75 species,including 42 bacteria,12 yeasts,and 21 filamentous fungi.After analyzing the functions of microbial food cultures during the key fermentation processes,the main functions of microbial food cultures were producing flavor substances and functional enzymes,improving the nutritional value,inhibiting competitive microbes,and improving the food texture,which aimed to provide scientific basis for improving the management of microbial food cultures in China.
