Estate Crops News – Microbial cellulose is one of the biopolymer in the form of nano-sized ribbons with a length of less than 100 nm and a width of 2-4 nm. Some bacteria are known to produce cellulose namely Acetobacter, Agrobacterium, Alcaligenes, Pseudomonas, Rhizobium, and Sarcina. Synthesis of bacterial cellulose forming microfibril bundle highly crystalline with elasticity modulus of 78 GPa as of 70 GPa fiber glass.

Microbial cellulose has water storage capacity, degree of polymerization, and the network structure is better than cellulose from plants. Nanofibril cellulose production of bacterial cellulose does not require the removal of hemicellulose 104 Volume 14 Nomor 2, Des 2015 : 103 – 112 and lignin as of plants so that the nano bacterial cellulose is a potential raw materials of nano composites in developing natural rubber (NR). Nano bacterial cellulose is potentially a strong raw material for nano composites, stronger than nano cellulose from plants. Development of natural rubber or natural rubber (NR) led to the development of rubber for specific purposes, one of which is elastomeric thermoplastics (ETPs), a group combining the characteristics of rubber material with thermoplastic material that is easily processed. Strengthening The concept to improve the strength of polymer materials, such as NA, with nano-filler bonding cellulose through the mechanism of rubber-filler-rubber is due to an increased interaction of nano-sized filler that has a large surface area. Bacterial cellulose such as Acetobacter xylinum grown in natural rubber latex medium, may result in 5 nm latex particle trapped in the cellulose matrix or vice versa, bacterial cellulose particles trapped in the matrix of natural rubber. Benefits of the bonding mechanism of in vivo bacterial cellulose and natural rubber matrix is develop rubber industry synthesizing nano-composite alloy rubber with bacterial cellulose for natural rubber diversification. The products resulted in the form of thermoplastic elastomer (natural rubber thermoplastic) is potentially to be used in automotive components and other specialty products.
