In connection with global warming, study to find new technological solutions that allow obtain wines characterized by a lower ethanol content and balanced in the acids sugars is relevant.One of use Lachancea thermotolerans yeast, which can metabolize some hexoses into lactic acid. present work comparative studies chemical composition from grape cultivar Cabernet Sauvignon Crimean autochthonous ...

The entomopathogenic fungus, Nomuraea rileyi (Farlow) Samson was mass produced in different liquid media. The nine media of various nutrient sources were evaluated to find out most suitable medium for growth, biomass and viability of N.rileyi. Sabouraud’s dextrose broth with yeast extract proved to be superior which gave significantly highest cfu (8.33x10/ml) and biomass (6.10g). The next best ...

Search for naturally grown food has stimulated the biotechnological production of carotenoids. Therefore, the use of the yeast Xanthophyllomonas dendrorhous has been researched due to its abilities to assimilate different sources as substrates and to produce high amounts of carotenoids. Furthermore, alternative sources have been used as the culture medium to reduce costs and environmental impac...

We measured Reynolds numbers Re of turbulent Rayleigh-Bénard convection over the Rayleighnumber range 2×10 <∼ R <∼ 10 11 and Prandtl-number range 3.3 <∼ σ <∼ 29 for cylindrical samples of aspect ratio Γ = 1. For R <∼ Rc ≃ 3× 10 9 we found Re ∼ R βeff with βeff ≃ 0.46 < 1/2. Here both the σand R-dependences are quantitatively consistent with the Grossmann-Lohse (GL) prediction. For R > Rc we fou...

Weare reporting an efficient method for microbial production of 4-thiouridine as an alternative to chemical synthesis. A loopful of a 10-day slant culture of S. libani NK-1 10134 grown on yeast extractstarch agar was inoculated into a 500-ml Erlenmeyer flask containing 1 10 ml ofa seed mediumcomposed of soluble starch 2.0%, glucose 0.5%, peptone 0.5%, yeast extract 0.5%, soybeanmeal0.5%, K2HPO4...

The green synthesis of silver nanoparticles (AgNPs) using plant extract, the cost-effective solution, and abundance environmental issue have been gaining much attention to scientists. Ganoderma lucidum (GL) commonly known as Lingzhi in Chinese Reishi Japanese, with a proven anticancer benefit, is discovered buffer zone Bach Ma National Park, Nam Dong district, Thua Thien Hue province. In this w...

• Carboxylic bola biosurfactants can compete with thiols as copper sulfide collectors. This effect is explained by selective precipitation and beneficial foaming properties. A non-ionic biosurfactant floats sulfides non-selectively entrainment. Yeast-derived amphiphiles have attracted growing attention in various industrial sectors green reagents. However, their physico-chemical properties rele...

background: in algeria the date wastes production is estimated at least 85.000 tones. date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced.objective: the aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. materials...

We describe a defective HeLa nuclear extract which is particularly deficient in step 2 of splicing reaction. With this extract we have studied the conservation of a second-step activity from yeast to human cells. We detected a S. cerevisiae second-step splicing activity that allows restoration of step 2 of the defective HeLa nuclear extract, which indicates that yeast purified fraction has a se...

OBJECTIVE The main objective of this work was to study the antipyretic and antibacterial activity of C. erectus (Buch.-Ham.) Verdcourt leaf extract in an experimental albino rat model. MATERIALS AND METHODS The methanol extract of C. erectus leaf (MECEL) was evaluated for its antipyretic potential on normal body temperature and Brewer's yeast-induced pyrexia in albino rat's model. While the a...
