“…Studies have shown that Actinobacteria were involved in degradation of some organic and inorganic compounds. For instance, Rhodococcus strains are involved in the removal of pharmaceutical compounds (Ivshina et al, 2018), tetrabromobisphenol A (TBBPA) (Xu et al, 2018) and dominant in naphthalene degrading enrichments (Rhee et al, 2004). It has also been demonstrated that the members of the genus Streptomyces produce laccase (i.e.…”

Despite emerging contaminants (ECs) are more and more monitored in environmental matrices, there is still a lack of data in marine ecosystems, especially on their fate and degradation potentials. In this work, for the first time, the degradation potential of synthetic musks (galaxolide and tonalide), UV filters (padimate O and octo-crylene) and a pharmaceutical compound (carbamazepine) was studied in marine sediment samples, under laboratory conditions using sediment slurry incubations under biotic and abiotic conditions. Minimum half life times under biotic conditions were found at 21 days, 129 days and 199 days for padimate O, galaxolide and carbamazepine, respectively. Enrichments conducted under anoxic and oxic conditions demonstrated that de-gradations after one month of incubation either under both biotic and abiotic conditions were limited under anoxic conditions compared to oxic conditions for all the contaminants. Novel aerobic bacteria, able to degrade synthetic musks and UV filters have been isolated. These novel strains were mainly related to the Genus Bacillus. Based on these results, the isolated strains able to degrade such ECs, can have a strong implication in the natural resilience in marine environment, and could be used in remediation processes.

This study focuses on the kinetics of a pure strain of bacterium Rhodococcus sp. SKC, isolated from phenol-contaminated soil, for the biodegradation of phenol as its sole carbon and energy source in aqueous medium. The kinetics of phenol biodegradation including the lag phase, the maximum phenol degradation rate, maximum growth rate (Rm) and maximum yield coefficient (Y) for each Si (initial phenol concentration, mg/L) were fitted using the Gompertz and Haldane models of substrate inhibition (R2 > 0.9904, RMSE < 0.00925). The values of these parameters at optimum conditions were μmax = 0.30 h−1, Ks = 36.40 mg/L, and Ki = 418.79 mg/L, and that means the inhibition concentration of phenol was 418.79 mg/L. By comparing with other strains of bacteria, Rhodococcus sp. SKC exhibited a high yield factor and tolerance towards phenol. This study demonstrates the potential application of Rhodococcus sp. SKC for the bioremediation of phenol contaminate.

“…These effects are often overseen and underestimated when the biodegradation of TBBPA is represented by specific strains enriched over time or isolated from contaminated sites and that have known gene expressions related to dehalogenation, aromatic rings cleavage, and O-methylation processes, for example, being able to biotransform TBBPA at high concentrations and controlled conditions (An et al, 2011;Peng et al, 2013 b;Zu et al, 2014;Gu et al, 2016;Ma et al, 2017;Xu et al, 2018;Gu et al, 2018;.…”

“…Additionally, TBBPA degradation may be positively or negatively associated with other substances present in wastewater, contaminated soils, and natural environments, such as anions (NO3 -, HCO3 -, SO4 2-) and metals (Cu 2+ , Fe II , Fe III , and Cd 2+ ) (Arbeli et al, 2006;Ma et al, 2017;Xu et al, 2018;Lin et al, 2020), besides other OMPs. Carbon sources are also involved in TBBPA removal by other means rather than co-metabolic or metabolic functioning of microbial communities: complexation to organic matter.…”

“…Associated to the fact that O-methylation enzymes are not specific, this reaction might function as a detoxification mechanism. O-methylation catalyzed by O-methyltransferases successively transfers a methyl group to the two hydroxyl groups of TBBPA (Cho et al, 2008;Xu et al, 2018). The bottom side of the process is that the replacement of the OH groups of TBBPA by MeO groups further increases the lipophilicity of TBBPA, turning it into a more bioaccumulative micropollutant.…”

e brincalhão, minha irmãzinha abusada (Gabriela) e meu doce e sempre paciente cunhado (Jonath). Vocês são meu mundo.Agradeço eternamente ao Marcelo: cada reunião, cada conversa, cada ajuda e cada risada. Você é o professor mais presente, humano e dedicado que já conheci. Você acreditou em mim (especialmente) quando eu não acreditei e você me ensinou tanto sobre a vida quanto sobre a ciência. Eu me sinto realmente sortuda por isso.Sou grata ao Jeppe, meu supervisor na Dinamarca: por cada orientação e conversa, por me dar a preciosa oportunidade de fazer parte de seu grupo, por tudo que você me ensinou, e principalmente por todas as portas que você abriu para mim. Você também acreditou em mim quando eu não acreditei e serei grata por isso para sempre.Minha irmã de alma, Rafaela. O mundo é um lugar melhor porque você está nele. Você é mais do que minha melhor amiga. Meus queridos amigos Inaê,
