“…Every year, the seafood processing industry discards a large amount of by-products, including viscera, shells, heads, squid pens, fins, and bones, even though they could be recycled to produce bioactive compounds like gelatin [1][2][3][4], enzymes [4][5][6][7][8][9][10][11][12][13][14][15][16][17], chitin [8,[18][19][20][21][22][23][24][25][26], chitin oligomers [7,11,12], α-glucosidase inhibitors (aGI) [27][28][29][30][31], carotenoids [32,33], and bioactive peptides [34][35][36][37][38][39][40]. Consequently, much research has gone into converting these by-products into bioactive products that have potential applications in biotechnological, agricultural, nutritional, pharmaceutical, and biomedical industries [1,…”

“…However, there are several drawbacks to the use of chemical procedures. With a more environmentally friendly production process, these marine byproducts could be used as carbon/nitrogen sources for microorganism bioconversion to various high-value products, including chitinase/chitosanase [6,[11][12][13]15,16,20], proteases [13,14], exopolysaccharides [41][42][43], and tyrosinase inhibitors [44].…”

Fishery processing by-products have been of great interest to researchers due to their beneficial applications in many fields. In this study, five types of marine by-products, including demineralized crab shell, demineralized shrimp shell, shrimp head, shrimp shell, and squid pen, provided sources of carbon and nitrogen nutrition by producing a protease from Paenibacillus sp. TKU047. Strain TKU047 demonstrated the highest protease productivity (2.98 U/mL) when cultured for two days on a medium containing 0.5% of shrimp head powder (SHP). The mass of TKU047 protease was determined to be 32 kDa (approximately). TKU047 protease displayed optimal activity at 70–80 °C and pH 9, with a pH range of stability from 6 to 11. TKU047 protease also showed stability in solutions containing surfactants and detergents. Based on its excellent properties, Paenibacillus sp. TKU047 protease may be a feasible candidate for inclusion in laundry detergents.

“…In contrast to this, Paenibacillus sp. AD showed maximum chitinase synthesis when ammonium sulfate was used as a nitrogen source 44 , while sodium nitrate was ideal for the production of chitinase in Stachybotrys elegans 45 . In the present study, KH 2 PO 4 and MgSO 4 showed a positive impact on chitinase production, whereas, their influence was insignificant during chitinase production by Pseudomonas fluorescens strain HN1205 46 .…”

Marine pollution is a significant issue in recent decades, with the increase in industries and their waste harming the environment and ecosystems. Notably, the rise in shellfish industries contributes to tons of shellfish waste composed of up to 58% chitin. Chitin, the second most ample polymer next to cellulose, is insoluble and resistant to degradation. It requires chemical-based treatment or enzymatic hydrolysis to cleave the chitin polymers. the chemical-based treatment can lead to environmental pollution, so to solve this problem, enzymatic hydrolysis is the best option. Moreover, the resulting biopolymer by-products can be used to boost the fish immune system and also as drug delivery agents. Many marine microbial strains have chitinase producing ability. Nevertheless, we still lack an economical and highly stable chitinase enzyme for use in the industrial sector. So we isolate a novel marine bacterial strain Achromobacter xylosoxidans from the shrimp waste disposal site using chitin minimal medium. Placket-Burman and central composite design statistical models for culture condition optimisation predicted a 464.2 U/ml of chitinase production. The culture conditions were optimised for maximum chitinase production recording up to 467 U/ml. This chitinase from the A. xylosoxidans was 100% active at an optimum temperature of 45 °C (withstand up to 55 °C) and pH 8 with 80% stability. The HPLC analysis of chitinase degraded shellfish waste reveals a major amino acid profile composition-arginine, lysine, aspartic acid, alanine, threonine and low levels of isoleucine and

“…Complete biodegradation of shrimp waste by a novel marine bacteria Paenibacillus sp. AD has also been reported [104]. Production of N-acetyl-D-glucosamine from chitin waste utilizing chitinase from Aspergillus terreus has been reported where fungus was isolated from marine environment and the chitinase was used for biotransformation of chitinaceous waste [29].…”

Chitinases are a group of hydrolytic enzymes catalysing degradation of chitin, the second most abundant polysaccharide in nature. Chitin is an essential structural component of most fungi cell walls, and exoskeleton of insects and crustaceans. Chitinases are synthesized in wide variety of organisms including plants, vertebrates, invertebrates, microbes (bacteria and fungi) and viruses. They perform various functions in different organisms depending upon the requirement of organisms like defense against pathogens and nutritional purpose. Nowadays chitinolytic enzymes have attracted global attention because of their different biotechnological and biomedical applications due to their hydrolytic activity on chitin and thus several chitinases have been reported and characterized. They are used mainly for biodegradation of chitin into beneficial compounds. These compounds have been illustrated to enhance human health through their antimicrobial, antioxidant, antitumor and anti-inflammatory properties. Chitinases have also been exploited for bio-control of phytopathogens and insects. Apart from these, the crucial use of chitinases in present time is in management of chitinous waste thus they have the potential to become essential tools in future green application. The present review focuses on the occurrence and varied distribution of chitinases. Here we also took a closer look at recent applications of chitinase in various fields.
