“…However, the phenomenon observed in the studies showed that after a 2 h-inoculation, Bacillus subtilis BSN313 entered the logarithmic and stable phases at 16 h. After 22 h, it entered the death stage. As for Bacillus paramycoides SP3, the major depletion of SeO 3 2− shifted from the exponential to the stationary phase with an increasing initial concentration [ 49 , 50 ]. The treatment group was supplemented with selenite, whereas the control had no selenite.…”

“…The delayed production of elemental selenium was also found in B. fungorum DBT1 in NB medium containing 2 mM SeO 3 2− . The research indicated that SeO 3 2− may be transformed into the intermediate reduced selenium form of organic selenide, resulting in the delay of the formation of elemental selenium [ 50 ]. Thus, the 76.4% reduction of SeO 3 2− by B. paralicheniformis Y4 within 72 h may be attributed to inorganic and organic forms of selenium, such as hydrogen selenide (H 2 Se) that exists in gaseous form [ 52 ].…”

“…Furthermore, the high negative charge on the surface of the nanoparticles could indicate a high degree of stability for biogenic nanoparticles without any processing or treatment, e.g., adding dispersants such as starch. We have demonstrated that SeNPs are electrokinetically stable in a wide pH range, with the zeta potential reaching −35.8 mV at a pH of 7, which is a range of great stability for application [ 35 , 49 , 50 , 56 ]. The determination of the sedimentation rate of the SeNPs is also crucial for determining their stability.…”

The inorganic selenium is absorbed and utilized inefficiently, and the range between toxicity and demand is narrow, so the application is strictly limited. Selenium nanoparticles have higher bioactivity and biosafety properties, including increased antioxidant and anticancer properties. Thus, producing and applying eco-friendly, non-toxic selenium nanoparticles in feed additives is crucial. Bacillus paralicheniformis Y4 was investigated for its potential ability to produce selenium nanoparticles and the activity of carboxymethyl cellulases. The selenium nanoparticles were characterized using zeta potential analyses, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). Additionally, evaluations of the anti-α-glucosidase activity and the antioxidant activity of the selenium nanoparticles and the ethyl acetate extracts of Y4 were conducted. B. paralicheniformis Y4 exhibited high selenite tolerance of 400 mM and the selenium nanoparticles had an average particle size of 80 nm with a zeta potential value of −35.8 mV at a pH of 7.0, suggesting that the particles are relatively stable against aggregation. After 72 h of incubation with 5 mM selenite, B. paralicheniformis Y4 was able to reduce it by 76.4%, yielding red spherical bio-derived selenium nanoparticles and increasing the carboxymethyl cellulase activity by 1.49 times to 8.96 U/mL. For the first time, this study reports that the carboxymethyl cellulase activity of Bacillus paralicheniforis was greatly enhanced by selenite. The results also indicated that B. paralicheniformis Y4 could be capable of ecologically removing selenite from contaminated sites and has great potential for producing selenium nanoparticles as feed additives to enhance the added value of agricultural products.

“…Bacillus paramycoides SP3, a native strain to the leachate of coal-mine-overburden rocks, was isolated by Borah et al [ 170 ] and investigated for its potential to produce Se nanoparticles by the biogenic reduction of selenite, one of the most toxic forms of selenium. B. paramycoides SP3 exhibited extremely high selenite tolerance (1000 mM).…”

It was generally believed that coal sources are not favorable as live-in habitats for microorganisms due to their recalcitrant chemical nature and negligible decomposition. However, accumulating evidence has revealed the presence of diverse microbial groups in coal environments and their significant metabolic role in coal biogeochemical dynamics and ecosystem functioning. The high oxygen content, organic fractions, and lignin-like structures of lower-rank coals may provide effective means for microbial attack, still representing a greatly unexplored frontier in microbiology. Coal degradation/conversion technology by native bacterial and fungal species has great potential in agricultural development, chemical industry production, and environmental rehabilitation. Furthermore, native microalgal species can offer a sustainable energy source and an excellent bioremediation strategy applicable to coal spill/seam waters. Additionally, the measures of the fate of the microbial community would serve as an indicator of restoration progress on post-coal-mining sites. This review puts forward a comprehensive vision of coal biodegradation and bioprocessing by microorganisms native to coal environments for determining their biotechnological potential and possible applications.

“…B. paramycoides strains have also been promising for the biocontrol of phytopathogens such as Fusarium oxysporum and Xanthomonas oryzae pv. oryzae (El-Sersawy et al 2021; Ooi et al 2022), in the degradation of acephate and methomyl widely used in agricultural pesticides (Omeiri et al 2022;Ren et al 2020), and the reduction of heavy metals to less toxic forms (Borah et al 2021) or by assisting the host as phytoremediator . Furthermore, research efforts have demonstrated its biotechnological applications.…”

Bacillus paramycoides is poorly understood bacterium with potential application as plant growth promoter and agent control bacterium to a more sustainable agriculture. B. paramycoides strain RZ3MS14 was previously isolated from guarana´s rhizosphere on Amazonian rainforest. The obtained RZ3MS14 draft genome comprised 28 scaffolds with a genome size estimated of 5,493,110 bp and a G + C content of 34.9%. We predicted 5,637 coding sequences (CDS). From phylogenomic analysis was observed that RZ2MS14 clustered in a monophyletic group with B. paramycoides strains. The ANI and digital DNA-DNA hybridization comparing RZ3MS14 and the B. paramycoides strain type NH24A2 was 98.5% and 73-80.6% respectively. RZ3MS14 harbors different genes related with plant growth-promoting as instance phosphorus solubilization and mineralization as well as auxin production by IPA pathway and others. Moreover, the RZ3MS14 draft genome presented the putative micrococcin, cerecidin, and paeninodin gene clusters, antibiotics related with pathogen control in addition of genes to VOCs production. Our results contribute to improve the knowledge concerning the molecular basis of B. paramycoides related with its vast application on agriculture.
