Degradation of parabens by Pseudomonas beteli and Burkholderia latens

Environmental Risk Assessment of Personal Care Products

“…Selvaraj et al [11] reported bacterial resistance in common pathogens in effluents of sewage treatment plants in India for parabens and suggested the possible transfer of resistant genes to other pathogenic bacteria in natural waters because of the release of untreated wastewaters directly into the environment. Moreover, the resistant strains have the potency to modify PCPs into toxic compounds [72] which may further affect the organisms.…”

Investigation of Current Infection-Control Practices for Ultrasound Coupling Gel

“…Bacterial growth was assessed for 7 days because specific bacteria may have the ability to break down parabens over time, and, therefore, bacterial growth rates could be affected. 3,10 Bacterial growth on the plates was assessed using a semiquantitative numeric value growth scale. 17,18 Semiquantitative growth scale numeric values are as follows: 0, no growth; 1, light growth; 2, medium growth; and 3, heavy growth.…”

“…3,9 Unfortunately, resistance to the antimicrobial activities of parabens has been described for some organisms, and, therefore, their bacteriostatic effects have been questioned. 3,5,7,[10][11][12][13] In addition to these steps taken by manufacturers, clinical communities have also published preliminary recommendations to minimize infection when using sterile and nonsterile medical ultrasound gel. In 2004, Health Canada published preliminary clinical recommendations.…”

Estudo da degradação do metil parabeno utilizando processos Fenton, foto-Fenton e eletro-Fenton

“…Roedores machos também exibiram diminuição em secreção de testosterona e algumas alterações do órgão reprodutivo após a exposição a butil e propil-parabenos. [10] A exposição humana estimada é de 76 mg dia [16] e também em tecidos de tumores de mamas. [14,17] As substâncias produzidas reagem com metais, ânions, compostos nocivos, etc., e sua aplicação depende do meio onde se encontram os poluentes.…”

“…As áreas do pico da amostra do padrão foram utilizadas para calcular a concentração de MeP nas amostra. [10,42] As amostras de degradação de MeP foram analisadas com as seguintes condições da Tabela 2.5.…”
