background: enzymatic hydrolysis of lactose is one of the most important biotechnological processes in the food industry, which is accomplished by enzyme β-galactosidase (β-gal, β-d-galactoside galactohydrolase, ec 3.2.1.23), trivial called lactase. orthogonal arrays design is an appropriate option for the optimization of biotechnological processes for the production of microbial enzymes. metho...

efficient use of agricultural wastes due to their recycling and possible production of cost effective materials, have economic and ecological advantages. a biological method used for degrading agricultural wastes is a new method for improving the digestibility of these materials and favoring the ease of degradation by other microorganisms. this research was carried out to study the possible bio...

Some Basidiomycota were chosen for studies of key ligninases synthesis (25°C, 30 days) in modified medium (shaken or not cultures) with added wheat straw. Liquid Czapek medium with straw yielded a higher amount of laccase than peroxidase, ground straw induced enzyme worse than chopped straw. With peroxidase the reverse dependencies were observed. Laccase of Lentinus edodes synthesized two enzym...

To reduce Cd phytoavailability in calcareous soils, the effects of soil amendments of red mud, rape straw, and corn straw in combination with zinc fertilization on Cd extractability and phytoavailability to spinach, tomato, Chinese cabbage and radish were investigated in a calcareous soil with added Cd at 1.5 mg kg-1. The results showed that water soluble and exchangeable Cd in soils was signif...

YUKSEL, S., L. TURGUT, M. YANAR, M. AKSU, G. KABAN and N. UNLU, 2011. Fatty acid composition, lean color and drip loss of the different muscles from young Holstein friesian bulls fi nished on diets containing varied proportions of wet sugar beet pulp and wheat straw. Bulg. J. Agric. Sci., 17: 696-703 The main purpose of this work is to determine meat quality attributes in 3 muscles of the Holst...

The present study aims to understand the influence of a reduced amount straw litter on goats’ lying comfort and hygienic characteristics milk straw. Lying behaviour (frequency, posture, location social context) 24 Alpine goats subjected two different treatments (Regular: 2 kg/straw/head + 1 kg straw/head/day, n = 12; Scarce: straw/head 0.5 12) was observed from video recordings using scan sampl...

Free standing and vertically aligned silicon rice-straw- like array emitters were fabricated by modified electroless metal deposition (EMD), using HF-H(2)O(2) as an etching solution to reduce the emitter density and to make the emitter end of the formed silicon rice-straw arrays shaper than those formed by conventional EMD. These silicon rice-straw array emitters can be turned on at E(0) = 4.7 ...

Oak woodchips, used for production of shiitake Lentinula edodes (Berk) Pegler, are increasingly difficult to obtain due to dwindling supplies. We investigated the effect of adding ground wheat straw as a substitute for portions of oak woodchips in substrate formulae on mushroom yield and size. We also determined the effect of mushroom cropping on relative feed value (RFV) by chemical analysis o...

Mao, H.L., Wu, C.H., Wang, J.K. and Liu, J.X. 2013. Synergistic effect of cellulase and xylanase on in vitro rumen fermentation and microbial population with rice straw as substrate. Animal Nutrition and Feed Technology, 13: 477-487. The in vitro gas test was conducted to investigate the effects of cellulase (CEL) and xylanase (XYL) on in vitro rumen fermentation and microbial population with r...

Straw mushrooms were grown on lead contaminated rice straw and stubble. Study materials were dried, acid digested, and analyzed for lead using flame atomic absorption spectrophotometry. The results showed the highest lead concentration in substrate was 445.350 mg kg⁻¹ in Treatment 3 (T3) and the lowest was BD (below detection) in Treatment 1 (T1). The maximum lead content in straw mushrooms was...
