Immobilization of Bacillus sp. in mesoporous activated carbon for degradation of sulphonated phenolic compound in wastewater

Metabolic Responses of Bacterial Cells to Immobilization

“…Immobilized cells are characterized by better biodegradation efficiency than free cells. The poor capabilities of xenobiotics degradation by microorganisms in the suspended state are mainly attributed to the irreversible binding of pollutants by extracellular polymeric substances, which hinder the effective transport [92,93]. Moreover, free cells degrading pollutants by metabolic activity are not stationary and not adapted to survive under mechanical and environmental stress [1].…”

Enrichment and immobilization of sulfide removal microbiota applied for environmental biological remediation of aquaculture area

“…Moreover, immobilization of microbiota will prevent microbial cells from being diluted and washed out in water (Hou et al, 2013); they are resistance to toxicity materials and high loadings (Sekaran et al, 2013). The most important thing is that they are relatively stable and convenient for operation (Mirzaei et al, 2014).…”

“…Thus, the marine sediment-originating sulfide-oxidizing microbiota is more suitable for sulfide biological removal in marine aquaculture environmental remediation. Moreover, research showed that microbial community with mixed strains perform more resistant to external interference such as disinfection treatment than single strain (Stijn van der Veen, 2011), and the immobilization of microorganisms would further protect them from shock load application and toxicity of chemicals (Sekaran et al, 2013). Although the application of immobilized SOB on sulfide removal has been reported in gas desulfuration in biotrickling filter (Tang et al, 2009), rare studies have been addressed in sulfide-rich aquaculture environmental remediation.…”

Simultaneous removal of Cr(VI) and phenol from binary solution using Bacillus sp. immobilized onto tea waste biomass

“…After acquiring maximum growth of bacterial cells in the nutrient medium, a known quantity of tea waste biomass was added to form a biofilm onto the surface of tea waste biomass by keeping it in in an incubator shaker for another 24 h. After attaining maximum growth of bacterial cells, the desired initial concentration of phenol and Cr(VI) was added to the suspension culture and their concentration in supernatant were measured at definite intervals of time until optimum conditions were achieved. Due to the possibility of volatilization of phenol during the experiment, control experiments were carried out at the same operating conditions [29,30].…”
