Preparation of Spherical Nanocellulose by Anaerobic Microbial Consortium
نویسندگان
چکیده
This work demonstrates the preparation of spherical nanocellulose from microcrystalline cellulose by controlled hydrolysis using anaerobic microbial consortium. The nanocellulose formed during the degradation of microcrystalline cellulose was separated by ultra filtration membrane and purified by differential centrifugation. The purified nanocellulose was characterized by nanoparticle size analyzer, atomic force microscopy and Fourier Transform infrared spectroscopy. While the conventional process of nanocellulose preparation using concentrated sulfuric acid hydrolysis resulted in the formation of nanowhiskers, controlled hydrolysis by anaerobic microbial consortium yielded spherical nanocellulose.

A novel microbial consortium from sheep compost for decolorization and degradation of Congo red
Congo red is a synthetic azo-dye dye with many industrial applications. The effluents containing azo dyes are causing several environmental hazards and thus should be treated prior to their discharge. The present work investigates the possible use of a novel microbial consortium from sheep compost for the decolorization of Congo red dye. The effect of different parameters including contact time...
متن کاملMetagenomic analysis for the microbial consortium of anaerobic CO oxidizers
Metagenomics analysis has been applied to identify the dominant anaerobic microbial consortium of the carbon monoxide (CO) oxidizers in anaerobic sludge. Reads from the hypervariable V6 region in the bacterial 16s rDNA were aligned and finally clustered into operational taxonomic units (OTUs). The OTUs from different stages in anaerobic CO condition were classified. Alphaproteobacteria, clostri...

متن کاملMetagenomic and metaproteomic analyses of a corn stover-adapted microbial consortium EMSD5 reveal its taxonomic and enzymatic basis for degrading lignocellulose
BACKGROUND Microbial consortia represent promising candidates for aiding in the development of plant biomass conversion strategies for biofuel production. However, the interaction between different community members and the dynamics of enzyme complements during the lignocellulose deconstruction process remain poorly understood. We present here a comprehensive study on the community structure an...
