“…Besides, the phenol tolerance properties of the test strains of our research at different concentrations suit well to the biochemical properties of B. cereus (Table 1) according to Singh, Singh, and Chandra (2009) who stated that few strains of B. cereus remain viable in a wide range of concentrations and biodegradation of phenol in batch culture by B. cereus pure culture and/or mixed culture with Paenibacillus spp. Even bioremediation of petroleum wastewater by hyper‐phenol tolerant B. cereus has also reported by Banerjee and Ghoshal (2017).…”

Background Bacillus cereus is a Gram‐positive, facultative anaerobic bacteria with few strains reported to be used as probiotics for animals and birds in recent times if the doses are formulated properly. Objectives To analyse the synergistic anti‐allergic potentiality of different Bacillus cereus strains on experimental in ovo and in vitro duck model, as probiotic immune stimulant. Materials and methods Different strains of Bacillus cereus from 29 isolates were identified through 16S rRNA gene sequencing from the milk samples of buffalo breeds of South Asia. The probiotic properties were tested in aspects of gram staining, catalase test, coagulase, test, bile salt tolerance, pH tolerance and phenol tolerance test. MIC50 and MIC90 levels were profiled using nine different antibiotics, and antimicrobial activity against eight different enteric pathogens was assessed. Finally, the test strains of Bacillus cereus (Colony Forming Unit [CFU] 30X1011) were combined‐infused at different concentrations in embryonated duck eggs to assess the post‐hatch anti‐allergic effects against histamine‐induced allergic reaction and their immunoglobulin E (IgE) level was tested. Results Molecular identification confirmed the test strains as B. cereus HKS 1–1, B. cereus LOCK 1,002 and B. cereus BF2, which were all motile, spore‐forming, catalase‐positive and rod‐shaped. All were 0.3% bile salt, 0.4% phenol and pH tolerant. Two‐way ANOVA test P values revealed that B. cereus BF2 was statistically significant (p < .0014) in bile salt tolerance test. B. cereus HKS 1–1 was significant in phenol and pH tolerance at p < .0002 and p < .0489, respectively. Besides, the test strains showed antibiotic sensitivity and antimicrobial activity to different enteric pathogens. In vivo model referred the test strains as effective in partial allergy reduction at same CFU but at different concentrations with p < .0001 among the groups. Conclusion The isolated and characterized strains of B. cereus showed partial immune‐stimulating potentiality against experimentally induced allergic reaction.

“…Annual facility releases to water (net to transfers) of Total Organic Carbon (TOC) for the seven-year period 2010–2016 were averaged to obtain mean annual facility TOC emissions (t/y). The ratio BOD/TOC in industrial effluents depends on the type of industrial waste and treatment applied, and may range from as low as 0.1–0.6 in petrochemical effluents, to 0.5–0.75 in pulp and paper mill facilities, to >2 for agro-industries (Dubber and Gray, 2010; Mook et al, 2012; Quayle et al, 2009; Banerjee and Ghoshal, 2017; Christian et al, 2017; Bustillo-Lecompte et al, 2018; Grötzner et al, 2018; Kwarciak-Kozłowska and Bień, 2018). Thus, the BOD/TOC ratio was introduced as a model calibration parameter to assess BOD sources from industries (BOD = TOC*bod/toc; Table 1).…”

Biochemical Oxygen Demand (BOD) is an indicator of organic pollution in freshwater bodies correlated to microbiological contamination. High BOD concentrations reduce oxygen availability, degrade aquatic habitats and biodiversity, and impair water use. High BOD loadings to freshwater systems are mainly coming from anthropogenic sources, comprising domestic and livestock waste, industrial emissions, and combined sewer overflows. We developed a conceptual model (GREEN + BOD ) to assess mean annual current organic pollution (BOD fluxes) across Europe. The model was informed with the latest available European datasets of domestic and industrial emissions, population and livestock densities. Model parameters were calibrated using 2008–2012 mean annual BOD concentrations measured in 2157 European monitoring stations, and validated with other 1134 stations. The most sensitive model parameters were abatement of BOD by secondary treatment and the BOD decay exponent of travel time. The mean BOD concentrations measured in monitored stations was 2.10 mg O 2 /L and predicted concentrations were 2.54 mg O 2 /L; the 90th percentile of monitored BOD concentration was 3.51 mg O 2 /L while the predicted one was 4.76 mg O 2 /L. The model could correctly classify reaches for BOD concentrations classes, from high to poor quality, in 69% of cases. High overestimations (incorrect classification by 2 or more classes) were 2% and large underestimations were 5% of cases. Across Europe about 12% of freshwater network was estimated to be failing good quality due to excessive BOD concentrations (>5 mg O 2 /L). Dominant sources of BOD to freshwaters and seas were point sources and emissions from intensive livestock systems. Comparison with previous assessments confirms a decline of BOD pollution since the introduction of EU legislation regulating water pollution.

“…Bacteria belonging to the genus Bacillus are frequently involved in bioremediation and other biotechnological processes [10,16,17]. Many Bacillus strains including B. subtilis, B. cereus, have been shown capable of degrading complex hydrocarbon mixtures such as the biodegradation of crude oil [10,16,[34][35][36][37].

Petroleum is, up to this date, an inimitable nonrenewable energy resource. Petroleum leakage, which arises during transport, storage, and refining, is the most important contaminant in the environment, as it produces harm to the surrounding ecosystem. Bioremediation is an efficient method used to treat petroleum hydrocarbon-contaminated soil using indigenous microorganisms. The degradation characteristics for a variety of hydrocarbons (hexane, benzene, gasoline, and diesel) were qualitatively and quantitatively investigated using Bacillus isolates. Microbiological and biochemical methods have been used including isolation of oil-degrading bacteria, enzymatic activities, the determination of physicochemical parameters, biosurfactant production and extraction assay, oil displacement assay, antimicrobial assay of the biosurfactants, and bioremediation kinetics. Consequently, of the 60 isolates capable of degrading different hydrocarbons at fast rates, 34 were suspected to be Bacillus isolates capable of growing in 24 h or 48 h on BH medium supplemented with 2% of hexane, benzene, gasoline, diesel, and olive oil, respectively. Among the 34 isolates, 61% (21/34) are capable of producing biosurfactant-like molecules by using gasoline, 70% (24/34) with diesel oil, 85% (29/34) with hexane, and 82% (28/34) with benzene. It was found that biosurfactant-producing isolates are extractable with HCl (100%), ammonium sulphate (95%), chloroform (95%), and ethanol (100%). Biosurfactants showed stability at 20°C, 37°C, 40°C, and 60°C. Biosurfactant secreted by Bacillus strains has shown an antagonistic effect in Escherichia coli, Shigella flexneri 5a M90T, and Bacillus cereus. The selected isolates could therefore be safely used for biodegradation. Substrate biodegradation patterns by individual isolates were found to significantly differ. The study shows that benzene was degraded faster, followed by hexane, gasoline, and finally diesel. The Bacillus consortium used can decrease hydrocarbon content from 195 to 112 (g/kg) in 15 days.
