Bacterial, or microbial, cellulose has different properties from plant cellulose and is characterized by high purity, strength, moldability and increased water holding ability. In natural habitats, the majority of bacteria synthesize extracellular polysaccharides, such as cellulose, which form protective envelopes around the cells.

Our cellulose is produced by these microbes converting liquid bio-mass waste products from coconuts beer, sugar, and liquid food streams into what we term plant-free & tree-free cellulose, we then apply our technology to convert the MC into fibres. The distinguishing features of microbial cellulose are shown in Table 1. Because the microbial cellulose ribbons are "spun" into the culture medium, membranes and shaped objects can be produced directly during the fermentation process, thus enabling a novel array of non-woven Fundamental features of microbial cellulose utilization are examined at successively higher levels of aggregation encompassing the structure and composition of cellulosic biomass, taxonomic diversity, cellulase enzyme systems, molecular biology of cellulase enzymes, physiology of cellulolytic microorganisms, ecological aspects of cellulase-degrading communities, and rate-limiting factors in nature.

Syndalor is a wound dressing product made of microbial cellulose to treat acute injuries where there is a loss of skin continuity as a result of: partial thickness burns, skin tears, diabetic ulcers and chronic ulcers. Therefore, microbial decomposition of cellulose cannot occurs without nitrogenous sources. ii. Temperature: Cellulose decomposition can occurs from temperature near freezing to above 65°C because both psychrophiles and thermophiles are involved in cellulose degradation.

Nanocellulose is a term referring to nano-structured cellulose. This may be either cellulose nanocrystal (CNC or NCC), cellulose nanofibers (CNF) also called nanofibrillated cellulose (NFC), or bacterial nanocellulose, which refers to nano-structured cellulose produced by bacteria.

It grows on top of a fermenting liquid, such as black or green tea, with sugar and an acid component. Cellulose irradiation under hyperalkaline conditions made the cellulose polymers more available for microbial degradation and the fermentation of the degradation products, produced acetic acid, and hydrogen, and causes a stop in ISA production.

Bacterial cellulose, an exopolysaccharide produced by some bacteria, has unique struc-tural and mechanical properties and is highly pure as compared to plant cellulose. This ar-ticle presents a critical review of the available information on the bacterial cellulose with special emphasis on its fermentative production and applications.

The high mechanical strength and remarkable physical properties result from the unique nanostructure of the never-dried membrane. This new cellulose comes from bacterial microbes called Microbial Cellulose (MC). The production process is very simple. Our cellulose is produced by these microbes converting liquid bio-mass waste products from coconuts beer, sugar, and liquid food streams into what we term plant-free & tree-free cellulose, we then apply our technology to convert the MC into fibres. The distinguishing features of microbial cellulose are shown in Table 1.
