background: soluble microbial products (smps) have an effective role on fouling of membrane in bioreactors (mbrs). the aim of this study was to survey the role of smps on mbrs used in treating municipal wastewater. materials: lowry and phenol sulfuric acid methods were used to measure carbohydrates concentrations and protein content, respectively. biochemical oxygen demand (bod), chemical oxyge...

background: during the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. lactococcus lactis (l. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. hence, l. lactis is an ideal candidate for mucosal immunotherapy. profilin (che a 2), the major allergen in chenopodium album, is one ...

Background: Lipase enzymes are of great importance in various industries. Currently, extensive efforts have been focused on exploring new lipase producer microorganism as well as genetic and protein engineering of available lipases to improve their functional features. Methods: For screening lipase-producing lactobacilli, isolated strains were inoculated onto tributyrin agar plates. Molecular ...

l- carnitine has been recognized as a new and important dietary supplementation, essential for human and animal nutrition. this study was conducted to evaluate the use of dietary l- carnitine supplementation and its effects on the growth (body final weight, daily growth rate (dgr), feed efficiency (fe), feed conversion ratio (fcr), daily feed intake  (dfi), protein efficiency ratio (per), lipid...

Abstract Soybean ( Glycine max L ) is a legume rich in protein, fat, vitamins, minerals and fibre. The nutritional value of soybeans the amino acid profiles processed fermented soybean (Tempe) products need to be studied. Tempe flour from black soybean, local (Anjasmoro variety) imported (USA soybean) were analyzed proximately, including carbohydrates (spectrophotometric method), protein (Kjeld...

d/l-Hybrid peptides are an attractive class of molecular modality because they able to exhibit high proteolytic stability and unique structural diversity which cannot be accessed by those consisting only proteinogenic l-amino acids. Despite such expectation, it has not been possible devise de novo d/l-hybrid capable disrupting the function a protein target(s) due lack effective method that reli...

the effect of cocl2 as an ethylene synthesis inhibitor on changes of protein pattern was investigated in potato (solanum tuberosum l.) plants cultivar white desiree. in vitro grown plants were subjected to ms medium containing 0, 5, 10, 15, 20, 30, 40 and 60 mg/l cocl2 for 4 weeks. different concentrations of cocl2 showed significant effect on the total soluble proteins. among different concent...

this experiment was conducted to evaluate the effects of supplemental l-arginine (arg) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. a total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. treatment groups were designed as a normal-prote...
