Simultaneous Production of Cellulose Nitrates and Bacterial Cellulose from Lignocellulose of Energy Crop.

This study is focused on exploring the feasibility of simultaneously producing the two products, cellulose nitrates (CNs) and bacterial cellulose (BC), from . The starting cellulose for them was isolated by successive treatments of the feedstock with HNO and NaOH solutions. The cellulose was subjected to enzymatic hydrolysis for 2, 8, and 24 h.

Evaluation of Chemical Composition of × Raised in Different Climate Regions in Russia.

Lignocellulosic biomass is of great interest as an alternative energy resource because it offers a range of merits. is a lignocellulosic feedstock of special interest, as it combines a high biomass productivity with a low environmental impact, including CO emission control. The chemical composition of lignocellulose determines the application potential for efficient industrial processing.

Properties and Hydrolysis Behavior of Celluloses of Different Origin.

The present paper is a fundamental study on the physicochemical properties and hydrolysis behavior of cellulose samples differing in origin: bacterial, synthetic, and vegetal. Bacterial cellulose was produced by Sa-12 in an enzymatic hydrolyzate derived from oat-hull pulp. Synthetic cellulose was obtained from an aqueous glucose solution by electropolymerization.

Static Culture Combined with Aeration in Biosynthesis of Bacterial Cellulose.

One of the ways to enhance the yield of bacterial cellulose (BC) is by using dynamic aeration and different-type bioreactors because the microbial producers are strict aerobes. But in this case, the BC quality tends to worsen. Here we have combined static culture with aeration in the biosynthesis of BC by symbiotic Sa-12 for the first time.

Biosynthesis of Bacterial Cellulose by Extended Cultivation with Multiple Removal of BC Pellicles.

Extended cultivation with multiple removal of BC pellicles is proposed herein as a new biosynthetic process for bacterial cellulose (BC). This method enhances the BC surface area by 5-11 times per unit volume of the growth medium, improving the economic efficiency of biosynthesis. The resultant BC gel-films were thin, transparent, and congruent.

Self-standardization of quality of bacterial cellulose produced by Medusomyces gisevii in nutrient media derived from Miscanthus biomass.

Bacterial cellulose (BC) was synthesized from biomass of Miscanthus grown in West Siberia. Miscanthus biomass was pretreated at atmospheric pressure with 4 wt.% solutions of HNO and NaOH in one and two stages.

Bacterial Nanocellulose Nitrates.

Bacterial nanocellulose (BNC) whose biosynthesis fully conforms to green chemistry principles arouses much interest of specialists in technical chemistry and materials science because of its specific properties, such as nanostructure, purity, thermal stability, reactivity, high crystallinity, etc. The functionalization of the BNC surface remains a priority research area of polymers. The present study was aimed at scaled production of an enlarged BNC sample and at synthesizing cellulose nitrate (CN) therefrom.

Early morphological changes in tissues when replacing abdominal wall defects by bacterial nanocellulose in experimental trials.

Experimental trials were done on five dogs to explore if an anterior abdominal wall defect could be repaired using wet (99.9%), compact BNC membranes produced by the Мedusomyces gisevii Sa-12 symbiotic culture. The abdominal wall defect was simulated by middle-midline laparotomy, and a BNC membrane was then fixed to open aponeurotic edges with blanket suture (Prolene 4-0, Ethicon).
