“…1 Applications of proteases in different industrial sectors destaining properties which reflected its potential for application in detergent industries (Rehman et al 2017). Extremely pH stable and thermostable proteases have been reported from Micromonospora chaiyaphumensis S103 (Mhamdi et al 2017) and from Aeromonas caviae (Datta et al 2016). Additionally, the proteases exhibited tolerance towards several organic solvents.…”

“…Keratinase exhibited activity and stability over a broad pH (5-10) and temperature range (50-90°C) and showed multifarious application spectrum for blood stain removal from fabric, gelatin hydrolysis from waste X-ray films and dehairing of animal hide . A thermostable and wide range pH stable protease from Micromonospora chaiyaphumensis S103 showed excellent potential for deproteinization of shrimp wastes for production of chitin (Mhamdi et al 2017).…”

“…As a result there is a paradigm shift from traditional concepts of chemical-based production and manufacturing to eco-benign processes that are equally efficient and economic (Sarrouh et al 2012;Nargotra et al 2016). Application of enzymes for industrial processes may contribute significantly towards development of environmentally benign processes (Bajaj and Jamwal 2013;Mhamdi et al 2017). Enzyme-based technologies promise efficient utilization of raw materials, generation of minimal or no wastes, and shun the usage of toxic chemicals Bajaj 2016, 2017).…”

Enzymes are the cornerstones of metabolism and constitute the fundamental basis for existence of life. However, recently enzymes are being implicated in diverse industrial processes because of their specific and fast action for efficient bioconversion of substrate to product, and their capability to save raw materials, energy and chemicals for various manufacturing processes. Enzymes are considered as environment-friendly (green) chemicals that may potentially help replacing completely or reducing the usage of hazardous chemicals for industrial processes, thus promising sustainable production and manufacturing. Among various industrial enzymes microbial proteases dominate the world enzyme market due to their multifaceted application potential in varied bioindustries like food, pharmaceutical, textile, photographic, leather and detergent. Promising applications of proteases in agricultural sector for instance may include biocontrol of pests, degumming of silk, selective delignification of hemp and wool processing. However, for successful industrial applications the proteases must be robust enough to suit the process conditions which are generally hostile. Proteases intended for industrial applications must have activity and stability over wide range of temperature and pH extremes for prolonged time periods and even in the presence of various potential enzyme inhibitors. Of various microbial proteases those from Bacillus spp. have got special significance because the latter are known for their ability to produce sturdy enzymes that might have suitability for industrial process conditions. The current article presents an interpretive summary of the recent developments on application potential of proteases for various industries.

Chitin Oligosaccharide (COS) Reduces Antibiotics Dose and Prevents Antibiotics-Caused Side Effects in Adolescent Idiopathic Scoliosis (AIS) Patients with Spinal Fusion Surgery

Antibiotics are always considered for surgical site infection (SSI) in adolescent idiopathic scoliosis (AIS) surgery. However, the use of antibiotics often causes the antibiotic resistance of pathogens and side effects. Thus, it is necessary to explore natural products as drug candidates. Chitin Oligosaccharide (COS) has anti-inflammation and anti-bacteria functions. The effects of COS on surgical infection in AIS surgery were investigated. A total of 312 AIS patients were evenly and randomly assigned into control group (CG, each patient took one-gram alternative Azithromycin/Erythromycin/Cloxacillin/Aztreonam/Ceftazidime or combined daily), experiment group (EG, each patient took 20 mg COS and half-dose antibiotics daily), and placebo group (PG, each patient took 20 mg placebo and half-dose antibiotics daily). The average follow-up was one month, and infection severity and side effects were analyzed. The effects of COS on isolated pathogens were analyzed. SSI rates were 2%, 3% and 8% for spine wounds and 1%, 2% and 7% for iliac wound in CG, EG and PG (p < 0.05), respectively. COS reduces the side effects caused by antibiotics (p < 0.05). COS improved biochemical indexes and reduced the levels of interleukin (IL)-6 and tumor necrosis factor (TNF) alpha. COS reduced the antibiotics dose and antibiotics-caused side effects in AIS patients with spinal fusion surgery by improving antioxidant and anti-inflammatory activities. COS should be developed as potential adjuvant for antibiotics therapies.

“…Mhamdi et al in their study, reported the evaluation, characterization and application of thermostable serine alkaline proteases from actinomycete strain Micromonospora chaiyaphumensis S103 for chitin extraction from shrimp shell (Penaeus kerathurus) waste powder. The percentage of deproteinization obtained after 3 hours of hydrolysis at 45°C and pH 8.0 with an enzyme/substrate (E/S) ratio of 20 U/mg had reached 93%, one of the best results in the literature compared to the use of other proteases[151]. In another work, crude digestive alkaline proteases from the viscera of Portunus segnis proved to be very efficient in the production of chitin by deproteinization of blue crab (P. segnis) and shrimp (P. kerathurus).…”

Huge amounts of chitin and chitosans can be found in the biosphere as important constituent of the exoskeleton of many organisms, as well as waste by worldwide seafood companies. Nowadays, politicians, environmentalists, and industrialists encouraged the use of these marine polysaccharides as renewable source, particularly when developed by alternative eco-friendly processes, especially in the production of regular cosmetics. The aim of this review is to outline the physicochemical and biological properties and the different bioextraction methods of chitin and chitosans sources, focusing on enzymatic deproteinization, bacteria fermentation, and enzymatic deacetylation methods. Thanks to their biodegradability, non-toxicity, biocompatibility, and bioactivity, the application of these marine polymers is widely used in the contemporary manufacturing of biomedical and pharmaceutical products. In the end, advanced cosmetic products based on chitin and chitosans are presented, analyzing different therapeutic aspects about skin, hair, nail, and oral care. The innovative formulations described can be considered as excellent solutions regarding problems in the various body anatomical sectors.
