Abstract
The diversity of cellulolytic bacteria from the rice-pulse system can be sourced for identification of efficient cellulose decomposing microbial strains. In the present study, the abundance, structural diversity, and cellulolytic potential of the culturable bacterial community were studied in 5-year old rice-pulse system under different resource conservation technologies. Higher cellulose (68% more) and xylanase (35% more) activities were observed under zero tilled soil. The populations of cellulolytic bacteria were significantly higher (44%) in zero tillage (ZT) treatment than those of conventional practice. Results revealed that the cellulolytic bacterial diversity was found to be significantly higher under ZT practice, but the present population may not be sufficient for effective recycling of organic wastes in this system. Out of 290 bacterial isolates, 20 isolates had significantly higher cellulolytic activities, of which the top three superior isolates were received from ZT practice. The cellulolytic bacterial diversity based on 16S rDNA sequencing data revealed that the Firmicutes was the most dominant phyla and the Bacillus spp. were the common genus, the observation also showed that there were 17 different haplotypes were recorded among 20 isolates of cellulolytic bacteria. The present findings indicated that long-term ZT in the rice-pulse system could be a unique source for efficient cellulose decomposing bacteria and further the efficient bacterial strains isolated from this system can be used as efficient bioinoculants for in situ as well as ex-situ decomposition of rice straw particularly in conservation agriculture.

Abstract
Cellulose is one of the major constituents of seaweeds, but reports of mechanisms in microbial seaweed degradation in marine environment are limited, in contrast to the multitude of reports for lignocellulose degradation in terrestrial environment. We studied the biochemical characteristics for marine cellulolytic bacterium Gilvimarinus japonicas 12-2T in seaweed degradation. The bacterial strain was found to degrade green and red algae, but not brown algae. It was shown that the bacterial strain employs various polysaccharide hydrolases (endocellulase, agarase, carrageenanase, xylanase, and laminarinase) to degrade seaweed polysaccharides. Electrophoretic analysis and peptide sequencing showed that the major protein bands on the electrophoresis gel were homologous to known glucanases and glycoside hydrolases. A seaweed hydrolysate harvested from the bacterial culture was found useful as a substrate for yeasts to produce ethanol. These findings will provide insights into possible seaweed decomposition mechanisms of Gilvimarinus, and its biotechnological potential for ethanol production from inedible seaweeds.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2017; 574:735-743.

Abstract
The alternation of drying and rewetting events could dramatically affect the biological and structural properties of soil and consequently influence nutrient transformation. To examine whether organic amendments could improve the resistance and resilience of microbial function (extracellular enzyme activities), community composition (phospholipid fatty acids), and soil structure to drying-rewetting alternation, cropland soils with or without wheat-straw amendment were allowed to desiccate in a microcosm for two months, followed by moist incubation for five weeks, and continuously moist treatments were maintained at 50% water holding capacity during the entire period, as a control treatment. Straw amendment increased microbial biomass, extracellular enzyme activities, the relative abundance of fungal groups, dissolved organic carbon, and proportion of large macroaggregates (>2000μm), but decreased mineral nitrogen and available phosphorus. The drying-rewetting treatment increased microbial biomass carbon and β-glucosidase activities by 10% and 13% in straw-amended soils, respectively, but not in unamended soils, and decreased the urease and alkaline phosphomonoesterase activities by >15% in unamended soils, but not in amended soils. The contents of fungi, actinomycetes, Pseudomonas spp., and Bacillus spp. decreased with drying, and more so with the subsequent rewetting, but recovered by the end of the experiment. The drying-rewetting treatment caused a decrease in the nitrate content in both soils (>10%) and an increase in the macroaggregates of straw-amended soils (~8%). These results indicated that improved soil aggregation, as a result of straw amendment, protected microbial communities from drought stress and that nutrient acquisition promoted the post-rewetting colonization of heterotrophic communities characterized by hydrolase production, which consequently facilitated aggregate re-formation. Thus, straw amendment positively contributed to aggregate turnover and to both microbial and enzymatic responses to drying-rewetting events, which suggests that straw amendment is favorable to maintain soil function under conditions of increasing rainfall variability.

Abstract
The production of endo-beta-1,4-glucanase by a Bacillus strain isolated from a hot spring in Zimbabwe was studied in batch culture, chemostat culture, and carbon dioxide-regulated auxostat (CO2-auxostat). The bacteria produced the enzyme in the presence of excess glucose or sucrose, but not under carbon-limited conditions in a chemostat using mineral medium. There was a specific growth rate dependent linear increase in enzyme production in glucose excess, nitrogen-limited chemostat cultures. A high specific growth rate of 2.2 h-1 and a high rate of enzyme production of 362 nkat (mg dry mass.h)-1 were attained under nutrient rich conditions in the CO2-auxostat. The bacteria had the highest specific growth rate and endo-beta-1,4-glucanase enzyme production at 50 degrees C. The maximum specific growth rate and the rate of enzyme production increased when yeast extract and tryptone were added in increasing amounts to the mineral medium used for cultivation in separate experiments. Increasing the glucose concentration in the CO2-auxostat cultures increased the rate of enzyme production but did not affect the specific growth rate.

Abstract
A modified cupric acetate method for the screening and quantitation of xylanolytic activities was comparable with the more widely used congo red method with respect to sensitivity and ease of use and was shown to have points of merit over the latter. The use of a non-linear correction, in comparison to the conventional linear one, for the effect of dilution on the quantitative plate assay was evaluated.
