“…While, the optimal pH of an alkaline protease from Bacillus halodurans C-125 is 12.0 (Tekin et al, 2021). For pH stability, AprBcp exhibited high residual activity (above 80%) in the range from pH 8.0 to 11.0 after 5 h of incubating at 25°C (Figure 4B), which is similar to previous reported alkaline protease (Rajkumar et al, 2011;Jagadeesan et al, 2020;Tekin et al, 2021).…”

“…AprBcp was strongly inhibited by PMSF and the relative activity was only 27.2 and 0.5%, respectively, in the presence of 1 and 5 mM PMSF, suggesting that serine is relative to the catalytic activity. Based on previous studies, we found that the activities of most serine proteases were completely inhibited by PMSF at a concentration of 5 mM (Barzkar, 2020;Jagadeesan et al, 2020;Chang et al, 2021). However, for an alkaline serine protease from Pseudoalteromonas sp.…”

“…Generally, the most reported alkaline proteases exhibit higher activity in the range of 8.0-11.0. The maximum activities of alkaline proteases from B. pumilus AR57 and Bacillus megaterium RRM2 are detected at 9.0 and 10.0, respectively (Rajkumar et al, 2011;Jagadeesan et al, 2020). While, the optimal pH of an alkaline protease from Bacillus halodurans C-125 is 12.0 (Tekin et al, 2021).…”

Proteases are important for decomposition of proteins to generate peptides or amino acids and have a broad range of applications in different industries. Herein, a gene encoding an alkaline protease (AprBcp) from Bacillus circulans R1 was cloned and bioinformatics analyzed. In addition, a series of strategies were applied to achieve high-level expression of AprBcp in Bacillus subtilis. The maximum activity of AprBcp reached 165,870 U/ml after 60 h fed-batch cultivation in 50 l bioreactor. The purified recombinant AprBcp exhibited maximum activity at 60°C and pH 10.0, and remained stable in the range from pH 8.0 to 11.0 and 30 to 45°C. Metal ions Ca2+, Mn2+, and Mg2+ could improve the stability of AprBcp. Furthermore, the recombinant AprBcp displayed great potential application on the recovery of protein from soybean dregs. The results of this study will provide an effective method to prepare AprBcp in B. subtilis and its potential application on utilization of soybean dregs.

Background: Asparagine is an amino acid that can be converted into aspartic acid and ammonia by the enzyme L-asparaginase. Some forms of cancer, such Acute Lymphoblastic Leukaemia (ALL) and Non-Hodgkin Lymphoma (NHL), respond well to this enzyme when employed as a chemotherapeutic drug. The purpose of this research was to find bacteria that can manufacture the enzymes L-asparaginasein marine slattern sediment which can be employed in commercial and industrial scale production. Methods: All of the strains were identified as Bacillus niacini spp. by biochemical and molecular testing. The strain belongs to the Bacillus genus, according to nutritional, biochemical, PCR and 16srRNA sequencing data. Results: According to the findings of this research, Bacillus niacin spp. have the potential to create a substance that is helpful in a variety of medical applications. The results of this study hint to the possibility that bacteria have the ability to produce antimicrobial compounds, which have the potential to be successful in a wide variety of environments. Conclusion: Numerous opportunities may arise for researchers interested in utilizing the medical potential of enzyme-producing bacteria if they are successfully isolated and screened from aquatic and terrestrial habitats.

“…This shows that India is rich in livestock and has vast resources of poultry. It was reported that the poultry industry produces 8.5 Billion tons of poultry waste worldwide and India generates poultry waste of 3.3 million tons annually which is valued as USD 28.13 Billion in 2023 and is expected to reach USD 44.97 Billion by 2032 due to booming livestock sector [8]. Environmental Assessment reports that India ranks fourth in the Mismanaged Waste Index (MWI) with 98.55 per cent of generated waste being mismanaged.…”

The main motive of this study was to find an auxiliary application of the discarded agricultural remnants and poultry waste. Rice straw and chicken feathers are disposed off as landfills or incinerated causing pollution and environmental threats after their primary consumption. In this study epoxy composites were made using varying proportions of these raw and alkali treated materials. Flexural strength of the composites decreased till 35% fiber loading, followed by an increase. Chicken feather composites showed increased impact strength with fiber addition. Alkali treatment improved the mechanical properties of rice straw composites. Alkali treated chicken feather composites showed better impact strength but no significant change in flexural strength. Hybrid composites explicated enhanced properties both before and after alkali treatment corroborating noteworthy interfacial adhesion and synergistic effect of these fibers as ascertained from SEM images. The study evinced a better option for averting environmental problems by recycling these disposed materials.
