“…Various techniques, such as measuring chitin weight loss, 14 C labeled experiments, fluorogenic substrate analogs, or colorimetric incubation, aid in assessing chitin hydrolysis (Arnold et al 2020 ). Temperature is a vital factor influencing chitin degradation rates, with higher temperatures often leading to increased activity (Kuzmina et al 2020 ). Chitinolytic bacteria may produce more chitin oligomers than they can utilize, which influences its degradation rates in the environment (Beier and Bertilsson 2013 ; Rathor and Gupta 2015).…”

Chitinases, enzymes that degrade chitin, have long been studied for their role in various biological processes. They play crucial roles in the moulting process of invertebrates, the digestion of chitinous food, and defense against chitin-bearing pathogens. Additionally, chitinases are involved in physiological functions in crustaceans, such as chitinous food digestion, moulting, and stress response. Moreover, chitinases are universally distributed in organisms from viruses to mammals and have diverse functions including tissue degradation and remodeling, nutrition uptake, pathogen invasion, and immune response regulation. The discovery of these diverse functions expands our understanding of the biological significance and potential applications of chitinases. However, recent research has shown that chitinases possess several other functions beyond just chitin degradation. Their potential as biopesticides, therapeutic agents, and tools for bioremediation underscores their significance in addressing global challenges. More importantly, we noted that they may be applied as bioweapons if ethical regulations regarding production, engineering and application are overlooked.

Thermophilic bacteria from litter deposited at Cipanas hot spring of mount Galunggung, Tasikmalaya, West Java, Indonesia, were isolated using a culture-dependent approach. Medium International Streptomyces Project (ISP) 1 solidified with gellan gum was used as an isolation medium. Isolation plates were incubated at 50°C for three weeks. The physicochemical analysis showed that the hot spring has a neutral pH and temperatures ranging from 50−56°C. A total of 16 bacterial isolates were obtained and purified. The analysis of partial 16S rRNA gene sequences data and phylogenetic analyses showed that they belong to Firmicutes and Proteobacteria phyla. The majority of bacterial isolates are spore-forming bacteria. The molecular identification based on the 16S rRNA gene sequence data showed that they belong to Aneurinibacillus thermoaerophilus (1); Brevibacillus gelatini (7); Bacillus licheniformis (1); Chelatococcus composti (1); Laceyella sacchari (2); Paenibacillus barengoltzii (1); and Pseudoxanthomonas taiwanensis (3). Percentage sequence similarities to their closest taxa were 91 to 99%. Phylogenetic analysis shed a light to the detection of candidates of novel taxa from litter of mount Galunggung hot spring.
