“…The results of the study by Zhang et al (2018a), showed that at 0.5 μg/L; DEHP, DBP, BBP, and DPP could almost be completely degraded by strain B1811 within 4 days in mineral salt medium under shaking conditions, while only 5.9% of the DMP and 42.9% of DEP present with short alkyl chains, were degraded by strain B1811 under the same conditions with DMP and DEP degraded to 0.471 and 0.285 μg/L respectively. Xu et al (2020), also found that strain BJQ0001 is also capable of successfully degrading substrates DMP, DEP, DBP, DIBP, and DEHP simultaneously when they are coexisting in the fermentation system at 0.2 μg/L of the PEs mixture, but with slightly reduced degradation rates. He et al (2020), studied bioaccumulation of PEs in muscle tissues of domestic livestock (pig, cattle and chicken) and fish in China.…”

“…In aquatic ecosystem, some PEs are stable, persistent, and resistant to natural degradation, hence previous studies demonstrated the feasibility of PEs from contaminated water to bio-accumulate and bio-magnify in the food chain Sun et al, 2015). Albeit, biodegradation is the dominant route for PEs degradation in the environment (Staples et al, 1997a;Chang et al, 2004;Xu et al, 2020;Das et al, 2021). Documented studies have reported that marine microalgal (Gao and Chi, 2015) and some microbial species possess the capability to degrade PEs (Ren et al, 2018;Yu et al, 2020), with microbial degradation considered the main route of PEs transformation (Yu et al, 2020).…”

“…Microbial degradation is however, generally affected by external environmental factors and typical lack of specific degrading bacteria in the aquatic ecosystem, which in turn makes PEs degradation difficult under natural conditions, hence their long half-life, that range from a few years to several hundred years (Fang et al, 2018;Das et al, 2021;Zhang et al, 2021). Interestingly, recent studies confirmed the ability of Bacillus mojavensis B1811 (Zhang et al, 2018a) and Paracoccus kondratievae BJQ0001 bacterium (Xu et al, 2020) to have high efficiency for the degradation of PEs. The results of the study by Zhang et al (2018a), showed that at 0.5 μg/L; DEHP, DBP, BBP, and DPP could almost be completely degraded by strain B1811 within 4 days in mineral salt medium under shaking conditions, while only 5.9% of the DMP and 42.9% of DEP present with short alkyl chains, were degraded by strain B1811 under the same conditions with DMP and DEP degraded to 0.471 and 0.285 μg/L respectively.…”

“…A study by He et al (2020), in China, found that untreated river water accounted for 79, 83, and 88% of the estimated PEs (DMP, DEP, BBP, DIBP, DNBP, DEHP, and DOP) daily intakes in toddlers, children and adults respectively, which exhibited an increasing trend with age, and this agreed with another study, also in China by Ji et al (2014), where water ingestion and/or absorption was the major source of exposure to DBP, DEHP, and DOP. It is also worth noting that domestic animal meat can also serve as another route of PEs exposure, especially pork, beef, chicken and some vegetables (He et al, 2020) and some crops producing eaten grains such as rice, maize and wheat (Sun et al, 2015;Xu et al, 2020), so it is befitting to suggest and recommend consumption of organic farm produces which contain no synthetic products.…”

Phthalate esters (PEs) are by far the most produced and extensively used synthetic organic chemicals with notable applications in many industrial products such as vinyl upholstery, adhesives, food containers, packaging materials, printing inks, adhesives, cosmetics, paints, pharmaceuticals munitions, and insecticides among other. PEs have long been recognised as ubiquitous organic pollutants of prime environmental concern, with urbanisation amongst the main cause and source of these compounds. Due to their notoriety, these compounds are known to pose devastating effects to living organisms including humans. The presence of PEs and their metabolites in the aquatic ecosystems is of concern primarily due to their endocrine disrupting and carcinogenicity properties. Several research studies have reported prevalence, exposure pathways, toxicity, and impacts of PEs in aquatic ecosystems and humans. Their principal routes of exposure could be direct or indirect, of which the direct route include contact, eating, and drinking contaminated foods, and the indirect route constitute aerosols, leaching and other forms of environmental contamination. PEs find way into water systems through means such as effluent discharges, urban and agricultural land runoff, leaching from waste dumps and other diffuse sources. High-end instrumentation and improved methodologies on the other hand have resulted in increased ability to measure trace levels (μg/L) of PEs and their metabolites in different matrices and ecological compartments of water or aquatic ecosystems such as lakes, oceans, rivers, sediments, wetlands and drinking water samples. In light of the above, this article provides an informed and focused information on the prevalence of phthalate esters in aquatic systems and related effects on living organisms and humans. Furthermore, techniques that have enabled the extraction and analysis of these PEs in aquatic samples are also explained. Future research outlooks and needs are also highlighted in this manuscript. This information will be used to better understand their temporal and spatial distributions in the aquatic systems and aid in devising prudent means to curtail their ecological footprints.

“…The majority of phthalates present in the atmosphere are due to gradually weathering or leaching from plastics and other materials containing phthalates (Wu et al 2010). Phthalates are not covalently linked to polymer matrices and can easily be distributed during their processing, use and disposal into the environment thus causing environmental pollution (Xu et al 2020). The presence of phthalate esters in the environmental matrices such as air, drinking water, food, soil, indoor dust, sediments, suspended particulate matter, pharmaceuticals and even in personal care products was mentioned by many researchers (Xu et al 2020;Zhang et al 2020).…”

Aim:The objectives of the present study were to explore the benzyl butyl phthalate (BBP) and dimethyl phthalate (DMP) degradation potential of Bacillus marisflavi RR014 isolated from the tap water of public toilet and also to optimize the phthalates degradation process using response surface methodology. Methods and Results: The minimal salt medium was used for the biodegradation analysis of phthalates. The quantification of phthalates and their intermediate metabolites identification were done by using UHPLC and LC-MS/MS respectively. The results revealed that B. marisflavi RR014 is capable of degrading both the phthalates under varying pH, temperature and salinity conditions. The formation of phthalic acid from the breakdown of BBP and DMP (500 mg l −1 ) in the medium was observed after 24 h. After 72 h, 61% of BBP and 98Á9% of DMP in the medium was degraded as monitored by UHPLC. The identification of intermediate metabolites by LC-MS/MS revealed that hydrolysis of BBP and DMP produces phthalic acid. Conclusions: The degradation rate of both the phthalates was increased as the parameters increased up to an optimum level. The three environmental factors (pH, temperature and salt concentration) strongly affect the rate of degradation of both the phthalates. The maximum degradation rate for both the phthalates was achieved at pH 7, temperature 35°C and salt concentration of 1% as observed from the central composite experimental design. Significance and Impact of the Study: It is the first report on the phthalates biodegradation potential of B. marisflavi RR014 isolated from the tap water of public toilet. The bacterium is capable of degrading BBP and DMP under varying pH, temperature and salinity, therefore, ideal to treat the phthalate contaminated environments.
