improvement of soil properties through sustainable agriculture requires suitable management of plant residues. this study was conducted to investigate the effect of different types and managements of plant residue on soil physical properties in a field experiment as factorial based on rcbd with three replicates. the first factor was residue type including barley straw and alfalfa residue, and t...

Food analysis is a tremendously broad field that constantly evolving. New methods have emerged to increase productivity, such as modern miniaturized and robotic analytical techniques. In this paper, micro-solid-phase extraction system (µ-SPE) for clean-up was combined with autosampler yield ready-to-analyze extracts. The evaluated its applicability in routine laboratories. new, automated, high-...

the chemical composition, ruminal degradability parameters, ruminal and post ruminal digestibility of saffron residues were determined using in situ and in vitro (gas production) methods. the harvested residues at late vegetative phase were compared with the residues harvested at the early dormant phase. the results showed that ndf and adf concentration of harvested residues at early dormant ph...

the aim of this study was to determine the optimum mixture ratios for composting separated cattle manure and pepper plant residues. five 127 liter laboratory-scale bioreactor were used to investigate of separated dairy manure addition on the composting process of greenhouse pepper plant residues. cattle manure is considerably rich in nitrogen. however, composting with cattle manure alone is not...

Filamentous fungi have been widely used to produce hydrolytic enzymes for industrial applications. Fungal enzymes amylase and glucoamylase were produced using a specific culture Aspergilus oryzae under solid state fermentation and the enzymes obtained were partially purified using isopropanol. Screening of four agricultural residues viz. rice bran, wheat bran, rice bran: wheat bran (1:1), rice ...

despite of beneficial effects of antibiotics in treatments of infectious diseases, antibiotic residues in meat, milk, eggs and another products can cause serious side effects for human health. it is clear that, antibiotic residues in food stuff, cause bacterial resistance, allergic reactions, toxicity, carcinogenic effects and change of natural micro flora of intestine in consumers. so, the aim...
