“…As with nitrogen, bioaugmentation has been demonstrated to have some success in the treatment of such compounds. Qu et al (2011) observed improved long-term stability of treatment systems for treating aromatic compounds.…”

“…Applications may include the use of a single strain or a combination of strains to produce a suitable consortium (Khehra et al, 2005;Qu et al, 2011). An individual strain may be selected for its ability to degrade a specific compound or due its role in a more complex degradation pathway.…”

“…Industrial wastewaters represent some of the most challenging waters requiring treatment and therefore offer insight into some of the more complex situations in which bioaugmentation may be implemented. Benefits may include more stable operating conditions, better flocculation characteristics, decreased start-up times, resistance to shock loads and better cold weather performance (Stephenson and Stephenson, 1992;Van Limbergen, Top and Verstraete, 1998;Guo et al, 2009;Bartrolí, Carrera and Pérez, 2011;Qu et al, 2011).…”

Bioaugmentation of activated sludge processes through the addition of microorganisms is employed with the aim of enhancing treatment, in particular the removal of priority pollutants. With industrial wastewaters, studies have covered target pollutants including ammonia and polycyclic aromatic hydrocarbons (PAHs): compounds that are regulated around the globe. However, bioaugmentation is a technique that has been associated with doubt in regard to its ability to benefit treatment processes. Failure of bioaugmentation has been reported to be associated with numerous factors that include the growth rate being lower than the rate of washout, insufficient inoculum size and substrate availability. Limitations of bioaugmentation can be overcome through techniques that include increased inocula dosing, pre-acclimatisation of inocula in side-stream reactors, addition of nutrients and surfactants and application of sufficient acclimatisation periods. Surveys of the literature show that a key area for further research should be towards acquiring a better understanding of the degradation pathways where bioaugmentation is applied. There also remains a need to undertake bioaugmentation efficacy studies at full scale with test and control streams. Further reporting on the economic viability of the technique is also necessary.

This study evaluated and optimized the influence of inoculum amount, initial pH, and nicotine load on the construction ofPseudomonassp. HF-1 bioaugmented system for tobacco wastewater treatment. The results demonstrated that the optimum condition for the set-up of strain HF-1 bioaugmented system was 1.10 mg/g (dry weight of strain HF-1/dry weight of activated sludge) of inoculum amount, initial pH 7.0, and 250–1000 mg/L nicotine load. Higher than 1.10 mg/g could lead to noncolonization of strain HF-1 in activated sludge and failure of set-up of this bioaugmented system. Higher than pH 8.0 could restrain the colonization of strain HF-1 in activated sludge. Even though strain HF-1 colonizes in the activated sludge when pH was above 8.0, the removal of nicotine and total organic carbon (TOC) was suppressed due to low activities of bacteria in the activated sludge. Nicotine load did not show inhibition effect on set-up of bioaugmented system, but the ability of TOC removal was restrained when the nicotine load was above 1000 mg/L. This work could offer vital parameters for the set-up of bioaugmented system to treat tobacco wastewater in engineering.

“…The Fig (8) showed that Bacillus badius D1 was actively involved in biodegradation process inducing biotransformation enzymes [41]. It is well reputed that effect of particular concentration, temperature, pH, carbon and nitrogen affect significantly on biodegradation [42][43][44][45]. The biotransformation enzyme induction was reported in case of ‫ﻻ‬ Proteobacterium and others [46][47][48][49].…”
