in current study, protein hydrolysates were produced using microbial proteases of alcalase, protamex and flavourzyme from yellowfin tuna viscera. the results indicated that, protein hydrolysate from alcalase, had significantly higher protein content, nitrogen recovery and degree of hydrolysis than the others (p 0.05). the results of amino acids composition revealed that all hydrolysates were al...

Lipase engineering database http://www.led.uni-stuttgart.de/ Lipases are heavily used in industry, especially for chiral resolution to produce compounds enantiospecifically. This database deals specifically with lipases. Directory of P450-containing systems http://www.icgeb.org/~p450srv/ Cytochrome P450 enzymes are widespread in biological systems, including bacteria and fungi. These monooxygen...

the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...

this experiment was conducted to evaluate the effects of different commercial multi enzymes and nutrients levels of diets on performance and carcass traits of broilers. in this experiment 288 day old ross – 308 broilers (male and female) were used as (2*4) factors include: two levels of nutrients in diets (ross- 308 nutrients recommendation and 5% less than ross- 308 nutrients recommendation) a...

The value of dietary exogenous enzymes in promoting growth and efficiency of feed utilization is well recognized in poultry industry. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients that have lower nutritional value like triticale, wheat, barley or sorghum. These crops are rich in non-starch polysaccharides (NSPs), and there ...

MOTIVATION DNA cytosine methylation is an important epigenetic regulator, critical for mammalian development and the control of gene expression. Numerous techniques using either restriction enzyme or affinity-based approaches have been developed to interrogate cytosine methylation status genome-wide, however these assays must be validated by a more quantitative approach, such as MALDI-TOF mass ...
