Bacterial Cellulose Production and its Industrial Applications

Abstract: Microbial cellulose has proven to be a remarkably versatile biomaterial and can be used in wide variety of applied scientific endeavors, such as paper product, electronics and biomedical devices. In fact, biomedical devices recently have gained a significant attention owing to increase in tissue-engineering products for both wound care and the regeneration of demand or diseased organs. So, microbial cellulose production, characterization and influence of additives during its production are important to understand the microbial pathway and create new application.

Up-To-Date Insight on Industrial Enzymes Applications and Global Market

Abstract: Industrial and household catalysis becomes more and more dependent on enzymes. This is not surprising since enzymes are able to catalyze all kinds of chemical reactions. Enzymes with the desired activity under industrial conditions can be obtained by optimizing process conditions and by protein engineering. The use of enzymes frequently results in many benefits that cannot be obtained with traditional chemical treatment. These often include higher product quality and lower manufacturing cost, less waste and reduced energy consumption. Key factors driving the market growth include new enzyme technologies endeavoring to enhance cost efficiencies and productivity, and growing interest among consumers in substituting petrochemical products with other organic compounds such as enzymes. Other factor propelling market growth includes surging demand from textile manufacturers, animal feed producers, detergent manufacturers, pharmaceutical companies, bioethanol producers and cosmetics vendors. The present paper aims to provide a review on industrial enzymes, highlighting on recent scientific advances, current applications in diverse industrial sectors and global market.

Aqueous Two-Phase Extraction Advances for Bioseparation

Abstract: Aqueous two-phase extraction (ATPE), unique liquid-liquid extraction, involves a transfer of solute from one aqueous phase to another. ATPE includes polymer–polymer type and polymer–salt type systems for the recovery of proteins. The protein must be recovered in a highly purified form in order to improve its quality, decrease energy consumption, reduce waste and minimize costs. To acquire the high value and achieve good control over processes, the reliable, multi-component products are required especially those with the ability to investigate complex processing conditions. The current reviewing paper discusses the most recent progresses for the recovery of biomolecules by using the ATPE, covering the mechanism, which controls the phase formation and the behavior of solute partitioning in aqueous twophase systems (ATPS) processes. The review discusses also the increasing application for the recovery of high-value bioproducts, the recent development of alternative low cost ATPS and disadvantages attributed to ATPS.

Carbon Dioxide Capture and Utilization using Biological Systems: Opportunities and Challenges

Abstract: Carbon dioxide capture and utilization (CCU), a concept of turning a greenhouse gas into a useful feedstock, is gaining much attention in recent years. Increasing CO2 emission into the atmosphere, from fossil fuel combustion and other anthropogenic activities, has forced us to source for more sustainable and economical routes of chemical syntheses. Instead of developing new chemical catalysts and CO2-based chemistry, we should perhaps learn from Nature. Over the past billions of years, Nature has evolved sophisticated mechanisms for carbon concentration, fixation and utilization, manifested through autotrophy. Many organisms, such as photosynthetic and chemolithoautotrophic organisms, display excellent ability in assimilating CO2 and converting it into complex molecules. Through the use of enabling technologies (e.g., genetic engineering and protein engineering), the range of CO2-derived bio-based products is expanding at a rapid pace. Chemicals that can be synthesized biologically include bio-plastics, bio-alcohols, biodiesel, to name a few. Continued research on multiple fronts and closed collaboration between scientists and engineers are required to further develop biological systems into viable chemical production platforms.

Rapid Conversion of Chicken Feather to Feather Meal Using Dimeric Keratinase from Bacillus licheniformis ER-15

Abstract: Dimeric keratinase from Bacillus licheniformis ER-15 completely degraded 25g boiled native chicken feather to feather meal within 8h at pH 8, 50°C and 150rpm. Feather degradation was a linear function of enzyme concentration and 2.5g chicken feather was degraded in presence of 1200U keratinase. Process for feather meal production comprised soaking of 25g feather in 250ml water followed by boiling for 10min-20min before enzyme addition. Feather meal thus produced was dried at 80°C and ground to obtain feather meal powder. Feather meal contained 14% nitrogen, 44% carbon with all essential amino acids and showed 73% in-vitro digestibility.
