Chicken egg shell and membrane were used as substrate for production of alkaline protease by Bacillus altitudinis GVC11. Maltose as additional carbon source enhanced enzyme production up to 13%. Addition of organic nitrogen sources like peptone and yeast extract increased enzyme production by 9% and 5%, respectively and inorganic nitrogen sources did not have any positive effect. The resultant ...
this study was aimed to determine the effects of different dietary levels of methionine and protein on the growth performance and carcass characteristics of broiler chickens. a total of 240 broiler chicks were distributed into a completely randomized design with a 2 × 3 factorial arrangement. experimental factors were: two levels of protein (20% or 24% for starter and 18% or 22% for grower), an...
an in vivo experiment was conducted to determine the effect of dietary betaine supplementation (betafin®) as a replacement for methionine on broiler performance and carcass characteristics. in a completely randomized design (crd) with five treatments of betaine levels (at 0, 25, 50, 75, and 100% in replacement for methionine) and five replicates of 10 birds/replicate, two hundred fifty-day-...
L-methioninase degrades methionine, which is essential in methionine-dependent cancer cells, resulting specific cell death. Normal cells can synthesize their own methionine amino acids even the absence of exogenous methionine. This selective targeting makes a promising therapeutic candidate for cancer. In this study, was partially purified from Brevibacterium linens BL2. The activity enzyme fou...
Soybean protein is one of the least expensive sources of dietary protein [3]. Soybean protein is considered to be a good substituent for animal protein [4], and their nutritional profile ex‐ cept sulfur amino acids (methionine and cysteine) is almost similar to that of animal protein because soybean proteins contain most of the essential amino acids required for animal and human nutrition. Rese...
