Aim: A study was conducted to evaluate the effect of supplemental yeast culture (Diamond V XPC Yeast Culture; YC) in broiler diets on carcass characteristics and humoral immune response. Materials and Methods: A total of 240 one-day-old broiler chicks (Ross 308) were randomly assigned to four YC dietary treatments of 60 birds each. The dietary treatments were 0 (control), 1, 1.25 and 1.5 g YC/k...

Materials and Methods Dietary supplementation of probiotic yeast ( ) was noted to improve the animal performance by improving the digestibility of nutrients and rumen bacterial number [1]. Addition of yeast culture, as a probiotic, in animal feeds improves fibre digestion [2], the cellulolytic activity of rumen microbes [3], and reduces the lactate accumulation and oxygen concentration in rumen...

The objective of the present study was to examine potential utilization yeast strain Pichia guilliermondii (Levica 27) on ruminal fermentation corn stover. Two in vitro treatments were evaluated: (A) filtered rumen liquid + powdered stover yeast-free culture medium and (B) inoculated with yeast. Samples collected at 0, 6, 12, 24 h examined for effects pH, ammonia nitrogen (NH3-N), fiber digesti...

in this study , samples of oily nuts using for human consumption ( pistachio- peanuts- walnut …..) were randomly obtained from markets in three geografical regions (south, east and west) of tehran. they were immidiatedly sent to mycology lab. then they were prepared for detection of fungi on sabour glucose , rose bangal and chapex agars. analysis of fungi were done by slide-culture, detection o...

An afebrile, 37-year-old, HIV-positive man, noncompliant with antiretroviral therapy, presented to the emergency department (ED) complaining of shortness of breath for 3 weeks. After an unremarkable chest radiograph, a bronchoalveolar lavage (BAL), and the collection of other diagnostic specimens, he left against medical advice. His CD4 count was 22/ml and his HIV viral load was 459,000 genomes...

A rapid technique for purifying plasmids from yeast Saccharomyces cerevisiae is described that yields high-quality DNA suitable for bacterial transformation, yeast transformation, and direct DNA sequencing. The method requires only small culture volumes and proprietary bacterial plasmid miniprep kits that allow one to simultaneously prepare a large number of samples in a very short period of ti...

Selenium enriched yeast is the most prevalent source of organic selenium for humans and animals. In this study, an effective capillary zone electrophoresis method was established to quantify total in biomass by measuring selenite level post incubated culture media. The detection could be achieved within 7.9 min under condition a mixture buffer 85 mM Na2HPO4 0.5 CTAB (pH 9.37), –5 kV separation ...

Estrogenic activity originating in unexpected places was encountered on three occasions during an investigation of whether Saccharomyces cerevisiae synthesized estrogens. In each instance, estradiol found in the conditioned yeast culture medium originated from an exogenous source and was not synthesized by the yeast. In the first instance, yeast grown in the laboratory showed a time-dependent i...

Yeast is the primary organism responsible for leavening of doughs. In this study, yeast samples were isolated from palm wine collected Nkpa in Abia State. The cultured on malt extract agar (MEA) medium at room temperature 28 o C to isolate three ascosporogenous strains ( Saccharomyces fragilis, cerevisiae, Pichia spp ) culture by using identification techniques such as their morphological, ferm...
