Hyaluronic acid (HA) is a linear polysaccharide with high molecular weight composed of disaccharide units of D-glucuronic acid (GlcUA) and N-acetylglucosamine (GlcNAc). HA is naturally present in vertebrate organisms, as well as in bacteria. HA can be obtained commercially through three routes: human umbilical cords, rooster combs, and strains of group C Streptococcus. This is a natural polysac...

Routine methods for the isolation of Neisseria gonorrhoeae employ various complex media in conjunction with devices designed to supply an atmosphere of approximately 10 per cent carbon dioxide. Recent investigations7 of the CO2 requirement of N. gonorrhoeae have shown that various strains of this microorganism can be grown on a Casamino-salts-glucose agar medium in the absence of CO2, provided ...

Barker's study on the nutritive requirements of Prototheca zopfii indicated that this colorless alga fails to grow in the absence of small amounts of yeast extract. A study of the growth factor requirements of Prototheca has shown that the active constituent of yeast extract necessary for the growth of this organism is thiamin (vitamin B(1)). Thiamin can fully replace the complex yeast material...

The methanol extract of Clitoria ternatea L. root (MECTR) blue flowered variety (Family: Fabaceae), was evaluated for its anti-pyretic potential on normal body temperature and yeast-induced pyrexia in albino rats. Yeast suspension (10 ml/kg body wt.) increased rectal temperature after 19 hours of subcutaneous injection. The extract, at doses of 200, 300 and 400 mg/kg body wt., p.o., produced si...

Xylose-to-xylitol bioconversion by Ca-alginate entrapped Candida guilliermondii cells in sugarcane bagasse hemicellulosic hydrolysate was carried out in erlenmeyer flasks using the repeated-batch mode of fermentation. The hydrolysate was supplemented or not with ammonium sulfate and/or rice bran extract at the beginning of each repeated batch. Altogether, six sets of three repeated-batches were...

Citrullus lanatus (Thunb.) (Cucerbitaceae) is a trailing annual herb native to India, Nigeria, and Africa, commonly known as Matsum Nakai. It thrives in all tropical, subtropical, warm temperate areas with hot summers. In seeds have long been used treat hypotensive diuretic effects, well kidney stones urinary passages. This study looked at the effects of methanol extract C. (MCL) on rhabdomyoly...

The adherence of three Candida species to human buccal epithelial cells (BEC) following treatment with different concentrations of date extract was investigated in vitro, as well as the effect of a mouth rinse with date extract on the adhesion of yeast to BEC. Adhesion of C. albicans, C. tropicalis and C. kefyr to BEC was significantly reduced after both short- and long-term periods of yeast ex...

In this study, twenty-five whey samples collected from dairy industries in the city of Isfahan. The sampleswere cultured on malt extract broth (MEB) and yeast extract glucose chloramphenicol agar (YGCA) media.Eleven yeast strains (designated M1 to M11) were isolated from the culture. The strains were identified bytheir morphological and physiological properties. Betagalactosid...

Tamarind (Tamarindus indica L.) is a nutrient-rich fruit that has an acid and exotic flavor. It widely consumed in natura at tropical countries such as India Brazil. The aim of this study was to evaluate the application tamarind substrate for production wine. pulp from ripe fruits used produce wine three different proceedings: (1) whole pulp, (2) without insoluble solids (3) pH adjusted 4.5. In...
