Tall fescue (Lolium arundinaceum) toxicosis research is often complicated by a reduction in intake of infected forage or seed, making treatment comparisons difficult. This study was conducted to develop a fescue toxicosis model that would allow for variations in DMI without altering the quantity of alkaloids consumed over the course of the experiment. Ground tall fescue seed and a tall fescue s...

Synthesis of silver nanoparticles (SNPs) by fungi is emerging as an important branch of nanotechnology due to its ecofriendly, safe, and cost-effective nature. In order to increase the yield of biosynthesized SNPs of desired shape and size, it is necessary to control the cultural and physical parameters during the synthesis. We report optimum synthesis of SNPs on malt extract glucose yeast extr...

The influence of temperature on the growth of the mould Penicillium roqueforti growing on malt extract agar was studied by correlating the produced heat (measured by isothermal calorimetry), ergosterol content (quantified by GC-MS/MS) and biomass of the mould at 10, 15, 20, 25 and 30 degrees C. The results were analysed with a simple metabolic model from which the metabolic efficiency was calcu...

antimicrobial activity, and antiproliferative activity against humantumor cell lines. In this paper, we describe the taxonomy of the producing organism, fermentation, isolation, physico-chemical properties and biological activities ofUCS1025A and B. The cultural and taxonomical characteristics of the producing fungal strain KY4917 were as follows. Colonies on 2% malt extract agar medium are 28 ...

During 2009–10, the presence of ascomycetous species in soil was studied in Fars province. Isolates were recovered from soil using modified Czapek (Raper et al. 1973), malt extract agar (MEA) and potato dextrose agar (PDA). Teleomorphic characteristics such as morphology of ascocarps, asci, ascospores and anamorphic characteristics such as conidiophores, phialides, conidia and chlamydospores we...

The present study focused on the separation and identification of the active compounds against head lice from the hexane extract of Annona squamosa L seed. Chromatographic and spectroscopic techniques revealed that two major compounds of the hexane seed extract were oleic acid and triglyceride with one oleate ester. The yields of these compounds were 13.25% and 7.74% dry weight, respectively. T...

the hawthorn fruits have been used as food and medicine for centuries. in the present study, pulp and seed extract of crataegus elbursensis rech. f. fruits belonging to the family rosaceae and native of northern part of iran were evaluated for the polyphenol contents, antiradical, antioxidant, and antibacterial activities. the total phenolic, flavonoid, and anthocyanin contents of methanolic pu...

the carob moth is one of the most devastating pests of pomegranate and some other products. various pest control measures have been undertaken in order to control this pest but none of them has been successful so far. in the current study the effects of cereal seed proteinaceous extracts including triticale and three wheat cultivars (mv17, aflak, and zare) have been studied on α-amylase and pro...

introduction: excessive physical exercise overproduces reactive oxygen species. even if elite sportsmen increase their antioxidant status by regular physical training, this improvement is not sufficient to limit free radical production during the competition period which can be detrimental to the body. this study evaluates the effect of grape seed supplementation along with aerobic exercise on ...
