Abstract Katuk leaves ( Sauropus androgynus (L.) Merr.; KL) are widely consumed by breast-feeding Indonesian mothers as it has been reported to increase breast milk production. It is hypothesized that supplementing KL in diets might crude protein (CP) concentration and fibre digestibility the diet. The had high CP non-fibre carbohydrate concentrations (333 332 g/kg dry matter; DM, respectively)...

Two multi-phasic models (logistic (LOG) and Michaelis-Menten (MM)) with three sub-curves were used to describe gas production kinetics of corn (CG), barley (BG), wheat (WG) and triticale (TG) grains. In each model sub curve, 1 describes the gas production caused by fermentation of the soluble fraction, gas production caused by fermentation of the non-soluble fraction is described in sub curve 2...

The distribution of the viral glycoprotein, gp 69/71, was studied on the cell surfaces of virus-producing and nonproducing cells. gp 69/71 was distributed evenly on cell membranes and on viral membranes of cells producing murine leukemia virus. gp 69/71 was distributed uniformly on cell membranes of thymocytes from NZB and strain 129 mice but was not detected on cell membranes of BALB/c thymocy...

Guanosine 5’-diphospho-β-l-fucose (GDP-Fuc) is an important and expensive nucleotide sugar only available in low quantities. We established two processes for the gram-scale production of GDP-Fuc with multi-enzyme cascades. used bifunctional enzyme fucokinase/GDP-fucose pyrophosphorylase from Bacteroides fragilis either ATP-regeneration system using polyphosphate or excess ATP. The optimized mod...

Natural gas hydrate accumulations were confirmed in the Dongsha Area of the South China Sea by the Guangzhou Marine Geological Survey 2 (GMGS2) scientific drilling expedition in 2013. The drilling sites of GMGS2-01, -04, -05, -07, -08, -09, -11, -12, and -16 verified the existence of a hydrate-bearing layer. In this work gas production behavior was evaluated at GMGS2-8 by numerical simulation. ...

An in vitro gas production technique was used to investigate the associative effects of untreated or biologically-treated linen straw with berseem hay (H). The linen straw (LS) was biologically treated with white rot fungi (TLS). Ground samples (200 mg DM) of H, LS, TLS and the mixtures (50% w/w) of H + LS and H + TLS were incubated in 100 ml glass syringes with buffered rumen fluid. Cumulative...

the goal of this study was to analysis the greenhouse gas (ghg) emissions of pasta production. data for this study was collected from durum wheat farms of three provinces of iran. data of soil properties, transportation and pasta factory stages were collected and analyzed, using simapro software, ecoinvent data base and global warming potential (gwp) 100 years method. epic model was used to cal...

Current ruminant feeding systems depend on knowledge of the composition of feeds and the rate and extent of degradation of feed organic matter (OM) and crude protein (CP) in the rumen. The effect of storage and preparation of samples on in vitro gas production and fermentation characteristics of two common forage species, namely alfalfa and ryegrass werestudied. Samples were prepared as fresh (...

An in vitro experiment was conducted to evaluate the effects of Aspergillus oryzae culture (AOC) and 2-hydroxy-4-(methylthio)-butanoic acid (HMB) on rumen fermentation and microbial populations between different roughage sources. Two roughage sources (Chinese wild rye [CWR] vs corn silage [CS]) were assigned in a 2×3 factorial arrangement with HMB (0 or 15 mg) and AOC (0, 3, or 6 mg). Gas produ...
