“…For instance, phenol is known to exhibit a much higher toxicity towards C. sorokiniana growth than salicylate, and therefore much lower efficiencies are expected when treating this compound in algal-bacterial systems [5]. However, the degradation of phenol entirely driven by photosynthetic oxygen supply was still feasible under similar conditions than those herein reported [18].…”

“…high or low pH and presence of toxic compounds) has been described, producing a consequent reduction in wastewater remediation. [11,[28][29][30] Since this chemical industry produce sodium hypochlorite (among other chemicals) the presence of this compound in the effluent could affect the bacterial growth due to their bactericide properties. However, Acinetobacter sp.…”

The use of native bacteria is a useful strategy to decontaminate industrial effluents. In this work, two bacterial strains isolated from polluted environments constitutes a promising alternative since they were able to remove several phenolic compounds not only from synthetic solutions but also from effluents derived from a chemical industry and a tannery which are complex matrices. Acinetobacter sp. RTE 1.4 showed ability to completely remove 2-methoxyphenol (1000 mg/L) while Rhodococcus sp. CS 1 not only degrade the same concentration of this compound but also removed 4- chlorophenol, 2,4-dichlorophenol and pentachlorophenol with high efficiency. Moreover, both bacteria degraded phenols naturally present or even exogenously added at high concentrations in effluents from the chemical industry and a tannery in short time (up to 5 d). In addition, a significant reduction of biological oxygen demand and chemical oxygen demand values was achieved after 7 d of treatment for both effluents using Acinetobacter sp. RTE 1.4 and Rhodococcus sp. CS1, respectively. These results showed that Acinetobacter sp. RTE1.4 and Rhodococcus sp. CS 1 might be considered as useful biotechnological tools for an efficient treatment of different effluents, since they showed wide versatility to detoxify these complex matrices, even supplemented with high phenol concentrations.

“…Therefore efforts to develop large scale PBR which prevent bacterial contamination is crucial to the advancement of the microalgae industry. A promising solution is UV treatment in order to sterilize PBR units (Essam et al 2006, Doud et al 2014). Doud and colleagues showed that a UV treated PBR used to grow Synechocystis sp., was maintained sterile for over three weeks in contrast to the non-treated PBR (Doud et al 2014).…”
