“…Many species are normally present in soil and in decaying animal and vegetable matter (Holt, 1994). Other studies demonstrated that species from Bacillus species played important roles in biodegradation and bioconversion of big molecular compounds (Akin, 1987;Holt, 1994;Rosevear, 1984), and Bacillus subtilis as well as Bacillus licheniformis are frequently reported cellulolytic species (Liu et al, 2004;Petre et al, 1999). The isolation of Halobacillus and Aeromicrobium spp.…”

“…3 and 4). Many fungi are able to break down polysaccharides such as celluloses and convert these polymeric compounds into sugars due to their capability to produce extracellular enzymes, and cellulase research was mainly focused on fungi in the past (Akin, 1987;Mandels, 1981;Petre et al, 1999;Rosevear, 1984;Wood, 1992). Few bacteria possess a complete multi-enzyme system for lignocellulose degradation; however, there has been increasing interest in cellulase production by bacteria because of the fast growth rate and many cellulolytic bacteria were isolated from various environments (Coughlan and Mayer, 1992;Li and Gao, 1997;Mandels and Reese, 1999;Petre et al, 1999).…”

Fifteen mesophilic bacteria with high C x cellulase activities were isolated and purified from a mixed-culture enriched from a flower stalks-vegetable waste co-composting system. A CMCase test showed that the enzyme activity of these isolates ranged from 7.9 to 28.0 U ml ؊1. Although filter paper degrading capability was low in single culture, significant synergetic cellulose degradation were detected in four groups of mixed cultures, their degradation rates were 23.5%, 26.3%, 19.4% and 24.5%, respectively. Study of morphological and physiological characters of five predominant isolates which possess high CMCase and had positive effect on synergetic cellulose degradation in mixed culture system showed that two of them were closely related to Bacillus pasteurii and Bacillus cereus, whereas the rest belong to the genus Halobacillus, Aeromicrobium and Brevibacterium, respectively.

Immobilization is one of the most effective and powerful tools used in industry, which has been studied and improved since the last century. Various immobilization techniques and support materials have been used on both laboratory and industrial scale. Each immobilization technique is applicable for a specific production mostly depending on the cost and sensibility of process. Compared to free biocatalyst systems, immobilization techniques often offer better stability, increased activity and selectivity, higher resistance, improved separation and purification, reuse of enzymes, and consequently more efficient process. Recently, many reviews have been published about immobilization systems; however, most of them have focused on a specific application or not emphasized in details. This review focuses on most commonly used techniques in industry with many recent applications including using bioreactor systems for industrial production. It is also aimed to emphasize the advantages and disadvantages of the immobilization techniques and how these systems improve process productivity compared to non-immobilized systems.

“…In Japan, USA and other countries immobilized microbial cells have been successfully applied for adsorption of heavy metals from dilute solutions [8,9], for purification of sewage [10] as well as for intensification of microbiological technologies (production of antibiotics, organic acids, sugar syrups, fermented drinks, etc.) [11]. It was shown that immobilized cells allow conducting biotechnological process over extended periods of time, under strict control of the process kinetics, _________________________ *corresponding author.…”

Bio-composite Material on the Basis of Carbonized Rice Husk in Biomedicine and Environmental Applications

The future prospects for biomedical and environmental engineering applications of heterogeneous materials on the basis of nano-structured carbonized rice husk are studied.The use of the nano-structured carbonized sorbents as delivery vehicles for the oral administration of probiotic microorganisms has a very big potential for improving functionality, safety and stability of probiotic preparations. The other possible mechanism of nano-structured carbonized sorbents is wound healing activity; the results demonstrated that the use of this material may offer multiple specific advantages in topical wound management. For bioremediation purposes nano-structured carbonized sorbents can be applied as bio-composite sorbent with immobilized microbial consortium consisting of bacterial strains with high oil-oxidizing activity.
