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 ...

A water-soluble complex containing ergosterol together with a component of yeast has been isolated. The complex can be isolated from commercial yeast extract to which ergosterol has been added or directly from whole yeast cells. The complexing component has the properties of a large polysaccharide and the binding between the sterol and the polysaccharide appears to be noncovalent. The complex i...

Food colorants from natural sources are preferred over the synthetic variants which elicits various adverse effects including teratogenicity and carcinogenicity. Pigments produced from Monascus spp. are of microbial origin and can be used as food grade biocolorants. The aim of the present work was to investigate the feasibility of Jackfruit seed as a substrate supplemented with carbon sources l...

In this study, it was aimed to examine and compare the effects of Hibiscus (Hibiscus sabdariffa L.) poppy (Papaver rhoeas extracts on some chemical, physical, microbiological sensory properties bread dough bread. The pH, L, b, chroma, hue values decreased by usage hibiscus extract, while a value increasing. It determined as lowest pH 4.13; L 39.23; b 5.08; chroma 6.55, angle 54.65 highest 7.20....

Two new fungal species of the genus Talaromyces, Talaromyces purpurogenus and Talaromyces trachyspermus from the Trichocomaceae family, were recovered during an investigation of fungal communities in soil collected from the Gangwon-do and Jeollanam-do provinces of Korea. These two species have not been previously officially reported from Korea. In this study, detailed descriptions of internal t...

background: artemisia species with common persian name of dermaneh are found all over iran and are used for treatment in infectious diseases such as malaria, hepatitis and other diseases. some artemisia species are used in traditionally as tonic and anti-helmintic in north of iran. objective: the aim of this study was to investigate chemical composition of the essential oil of artemisia hausskn...

A practical medium for reducing costs and enhancing both biomass and intracellular polysaccharide (IPS) production by a newly screened Agaricus blazei AB003 has been selected. The results show that IPS production was growth-associated, that a combination of corn flour extract and glucose was the best carbon source, and that a combination of wheat bran extract and yeast extract was the best nitr...

Cell-free yeast extract has been successfully used to catalyze the enzymatic formation of 11 out of the 14 naturally occurring modified nucleotides in yeast tRNAPhe(anticodon GAA). They are m2G10, D17, m22G26, Cm32, Gm34,psi39, m5C40, m7G46, m5C49, T54 andpsi55. Only D16, Y37 and m1A58 were not formed under in vitro conditions. However, m1G37was quantitatively produced instead of Y37. The natur...

Antibacterial and antifungal activity of ethanolic extract of grapefruit (Citrus paradisi Macf., Rutaceae) seed and pulp was examined against 20 bacterial and 10 yeast strains. The level of antimicrobial effects was established using an in vitro agar assay and standard broth dilution susceptibility test. The contents of 3.92% of total polyphenols and 0.11% of flavonoids were determined spectrom...
