“…Acclimatization process was employed with some variation from [ 11 ] to increase the produced enzyme via continuous passing the keratinolytic isolates through 20 cycles of culturing and sequential sub-culturing on BSM. Each cycle consists of 3 days of incubation followed by withdrawal of bacterial inoculum for the next cycle.…”

Highlights After acclimatization , Bacillus cereus isolate produced up to 809 ± 2.49 U/mL of keratinase in 2 days only. Bacillus cereus keratinase is stable over wide range of temperatures. Keratinase decreased the treatment time and increased the treatment efficiency of fucidic acid in skin animal model.

“…Bacillus species are well known as highly resistant spore-forming bacteria. They possess excellent characteristics and are extremely efficient for many agricultural, environmental and industrial applications (El-Bestawy et al, 2013). Bacillus species have been reported to be excellent degraders of cypermethrin (Bhatt et al, 2019), DDVP (Zhang et al, 2021) and glyphosate (Aso et al, 2021).…”

Food insecurity is a global pandemic. In 'The State of Food Security and Nutrition in the World' 2020, it was estimated that almost 690 million (8.9 per cent) of the world's population went hungry in 2019, and the statistics keep rising (FAO, IFAD, UNICEF, WFP and WHO, 2020). One of the interventions aimed at stemming food insecurity is to increase crop yield. Healthy soils produce healthy crops and soil quality is directly linked to food quality and quantity (FAO, 2015).In seeking ways to control disease carriers and different groups of pests, the agricultural industry witnessed a huge input of pesticides to maximize crop production and meet the demands for higher supplies of food for the fast-growing human population (Pal et al., 2006).

“…Biodegradation includes the utilization of living microorganisms or their enzymes to detoxify pollutants, which has been by and large considered as a successful and cost-effective method for the removal of contaminants 35 . It was emphasized that different microbes had the capacity of efficiently degrading ATZ including Chelatobacter heintzii 36 , Enterobacter (E. cloacae), Bacillus (B. cereus and B. anthracis), Pseudomonas (P. aeruginosa, P. balearica, P. indica and P. otitidis), Ochrobactrum (O. intermedium) and Providencia (P. vermicola) 37 and P. fluorescence + P. putida 38 . In Present study, two exceedingly successful strain of Bacillus spp .…”

In this study, a novel immobilizing carrier with α-Fe2O3 magnetic nanoparticles was developed and used for immobilization of atrazine-degrading bacterial isolates of Bacillus spp. Since the free cells of microorganisms generally not succeed to degrade pollutants; thus, extra treatments are alluring to make strides biodegradation. Scanning electron microscope (SEM) images appeared that after immobilization the bacterial cells were totally retained and entirely distributed on the surface of α-Fe2O3 magnetic nanoparticles. The performance of α-Fe2O3 immobilized cells in atrazine (ATZ) degradation was compared with the free cells, which was about 90.56% in 20 days. Experimental results exhibited that ATZ could be degraded at a broad range of physicochemical parameters viz. pH (4.0 to 9.0), temperature (20 to 45 °C), ATZ concentration (50 to 300 mg L−1) and agitation speed (50 to 300 rpm), which underlines that α-Fe2O3 immobilized cells could tolerate a higher range of ATZ concentration as compared to free cells. This research demonstrated that α-Fe2O3 could be applied as a potential carrier in cell immobilization and biodegradation of ATZ herbicide with greater efficiency.
