The quantity of rice straw and straw management survey only did in WinterSpring and Fall-Winter crops in An Giang, Dong Thap, Kien Giang province and Can Tho City. The research focused on the evaluation of simply biological pretreatment, material size and mixing rate of rice straw/hyacinth with pig manure in anaerobic batch and semi-continuous condition in vitro; trial producing biogas in polyethylene digester type (PE) in household scale in vivo

The experiment was conducted in experimental Farm, Regional Research Station, Anand Agricultural University from July to November 2018toestimate the extent of variability present in rice genotypes with respect to yield and its component traits. The estimates of genotypic and phenotypic variances for the characters like plant height, effective tillers per plant, number of grains per panicle, grain yield per plant, straw yield per plant, harvest index and 1000 grain weight, genotypic variance contributed larger in phenotypic variance.

The field experiment was conducted to study microbial product and urea effects in decomposing rice straw on the growth and yield of rice grown in acid sulfate soils in a three rice cropping system, at Tam Nong district, Dong Thap province, in the Autumn-Winter crop of 2016. The experiment was carried out in factorial design with 2 factors in randomized complete blocks with 3 replications.

In recent years, rice straw open burning (RSOB) activity has commonly occurred after the harvest in the countryside of Hanoi. This activity has caused negative impacts on air quality, especially it emits a large amount of black carbon (BC), a short lived climate pollutant (SLCP). As the other SLCPs , BC directly affects human health and ecosystem. This paper presents the results of measured BC concentrations in RSOB season in Lai Yen commune, Hoai Duc district in Hanoi.

We have isolated a laccase (lac1) from culture fluid ofVol-variella volvacea, grown in a defined medium containing 150lMCuSO4 , by ion-exchange and gel filtration chroma-tography. Lac1 has a molecular mass of 58 kDa as deter-mined by SDS/PAGE and an isoelectric point of 3.7. Degenerate primers based on the N-terminal sequence of purified lac1 and a conserved copper-binding domain were used to generate cDNA fragments encoding a portion of the lac1 protein and RACE was used to obtain full-length cDNA clones. ...

Cellulose and wheat straw degradation byRuminococcus albuswas moni-tored using NMR spectroscopy. In situ solid-state 13 C-cross-polarization magic angle spinning NMR was used to monitor the modification of the composition and structure of cellulose and 13 C-enriched wheat straw during the growth of the bacterium on these substrates.

Cellulosomes produced byClostridium cellulolyticumgrown on cellulose were purified and separated using anion-exchange chromatography. SDS⁄PAGE analysis of six fractions showed variations in their celluloso-mal protein composition. Hydrolytic activity on carboxymethyl cellulose, xylan, crystalline cellulose and hatched straw differed from one fraction to another.

A cock was once strutting up and down the farmyard among the hens when suddenly he espied something shinning amid the straw. ‘Ho! ho!’ quoth he, ‘that’s for me,’ and soon rooted it out from beneath the straw. What did it turn out to be but a Pearl that by some chance had been lost in the yard? ‘You may be a treasure,’ quoth Master Cock, ‘to men that prize you, but for me I would rather have a single barley-corn than a peck of pearls.’ Precious things are for those that can prize them. ...
