in this study the effect of different nitrogen source substrates on the amount of chitosan production by aspergillus niger was investigated. a. niger ptcc 5012 from the persian type culture collection (ptcc) was grown on soy bean, corn seed and canola residues at 30 °c for specified cultivation days under sterilized conditions. chitosan was extracted from the fungal mycelia using hot alkaline a...

The seed of oilseed plants, including Arabidopsis and several crop species, such as soybean, sunflower, and canola, contain a major store of oil in the form of triacylglycerol (TAG), which provides carbon and energy for seed germination and seedling growth. During germination and seedling development, TAG stored in oil bodies is broken down into fatty acids through the action of lipases. Fatty ...

to study the effect of dietary animal and plant lipids on gonadal differents and sex steroid hormones levels of blood in rainbow trout (oncorhynchus mykiss), the four diets was formulated based on 15% fat. the control uses 100% oil, fish oil was treated in the first, second and third respectively 25% and 75% fish oil, soybean oil, canola and cotton were used. after six weeks of feeding fish wit...

Two experiments were conducted to determine DE and ME and the apparent ileal digestibility (AID) and the standardized ileal digestibility (SID) of CP and AA in 4 sources of canola meal (high-protein [CM-HP], high-temperature-processed [CM-HT], low-temperature-processed [CM-LT], and conventional [CM-CV] canola meal) and in conventional soybean meal (SBM) fed to growing pigs. In Exp. 1, 48 growin...

three hundred and sixty broiler chicks (ross 308) were employed in an experiment from 6 to 49 days of age to evaluate the effect of replacing canola meal for soybean meal either with or without enzyme supplementation. dietary treatments included 5 substitution levels (0, 25, 50, 75 and 100%) at two enzyme concentrations of: 0 and 400 g/ton in a 5×2 factorial layout experiment. the enzyme mixtur...

Highlights Cottonseed oil (CSO), a cotton byproduct, has advantages for climate change compared to other seed oils. Results show that the cultivation phase is main impact driver all vegetable oils analyzed in this study. Refined CSO (U.S.) can reduce impacts by up 83% as analyzed. Abstract . Edible are major source of and an environmental concern processed food industry. This study consists cra...

Two experiments were conducted to determine DE and ME and the standardized ileal digestibility (SID) of CP and AA in 2 sources of high-protein canola meal (CM-HP1 and CM-HP2), conventional canola meal (CM-CV), and soybean meal (SBM) fed to growing pigs. In Exp. 1, 40 barrows (51.5 ± 4.0 kg initial BW) were housed in metabolism cages and randomly allotted to 1 of 5 diets with 8 replicate pigs pe...
