As major structural components of plant cell walls, cellulose and hemicellulose are degraded and fermented by anaerobic microbes in the rumen to produce volatile fatty acids, the main nutrient source for the host. Cellulose degradation is carried out primarily by specialist bacteria, with additional contributions from protists and fungi, via a variety of mechanisms. Hemicelluloses are hydrolyzed by cellulolytic bacteria and by generalist, non-cellulolytic microbes, largely via extracellular enzymes. Cellulose hydrolysis follows first-order kinetics and its rate is limited by available substrat

Abstract:

Lignocellulosic material that includes hemicellulose, cellulose and lignin (lignocellulosic complex) is present in the plant cells. The hydrolysis process of the lignocellulose biomass into glucose in the presence of lignocellulytic enzymes is an area of concern in the production process of cellulosic biofuel. Microorganisms like fungi have the ability for degrading the plant cell wall by an enzyme set which acts in coordination. This moves in a direction to release glucose freely. Another challenge is the modification in the plant cell architecture. Along with this, the capacity of microorgan

Vast volumes of Acid Mine Drainage (AMD) are still being generated in South Africa, due to decant from both active and closed mines. Research to find a cost effective, environmentally friendly treatment system to reduce the salinity and to neutralise the acidity of AMD is ongoing. The study presented here showed that high sulphate removal efficiencies were achieved applying the biological treatment technology, thereby using the degradation products of grass-cellulose as the carbon and energy sources. The process was conducted at 25°C, as opposed to 37°C described previously, using a one-stage

Abstract:

Inoculating microbial inoculants to speed up the decomposition of returning straw is currently a hot topic. Meanwhile, the soil moisture content (SMC) could change the diversity, abundance, and metabolism of the soil microbial community structure, which affects the straw degradation rate under the straw returning condition. In this research, rumen microorganisms with strong decomposing abilities in natural systems were used as inoculants to promote straw decomposing and returning to the field. The effects of the SMC on straw decomposition under rumen fluid (RF)-induced returning were investiga

Most of the agricultural, forest and field crop litters are consisting lignocelluloses, cellulose, hemicellulose and lignin. Among these cellulose is most predominant constituent followed by hemicellulose and lignin. The lignin together with the hemicellulose, encrust the cellulose chains forming a barrier which prevents wetting and access of cellulose-degrading enzymes therefore, the decomposition of litters can be achieved by breaking this association at first.

Insects are most versatile organisms in animal kingdom. They are about to live in different environment and are successful in habiting most of the niches. The adaptability of insects are due to the enzymes they produce and the symbiotic relationship they have with microorganisms. Cellulose is the fibre which provides strength to plant cell. It is flexible and strong and higher animals are not able to digest it on their own. Some bacteria, fungi and protozoa produce cellulase which breaks down the cellulose chain into shorter fragments enabling them to utilize the molecules for their growth. Ma
