- What is a standard state of terephthalate?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2.
- How does DOTP affect biofilm?
- Increased DOTP content (from 1 to 10% v/v) in PVC film led fatality of microorganisms in biofilm. Reactive oxygen species increased with increasing DOTP concentration. The ecological impact of DOTP and its potential for contamination are significant concerns for further research.
- Does DOTP biodegradation affect microbes?
- This study assessed the biodegradation and toxicity of DOTP on microbes, focusing on its impact on biofilms and microbial metabolism using Rhodococcus ruber as a representative bacterial strain. DOTP is commonly found in mass fractions between 0.6 and 20% v/v in various soft plastic products.
- Does DOTP affect microbial communities?
- An increase in the volume of dead cells (in the plastisphere biofilm) was observed with increasing DOTP concentrations in experiments using PVC films, indicating the potential negative impact of DOTP on microbial communities.
- Are terephthalate plasticizers safe?
- DEHT is a general purpose plasticizer that is considered safer than ortho - phthalate plasticizers due to its reduced toxicity profile. The terephthalates exhibit none of the peroxisome proliferation of liver enzymes that some ortho - phthalates have shown in several studies.
- How did the biodegradation of DOTP occur?
- The biodegradation of DOTP proceeded through a series of hydrolysis reactions. Initial hydrolysis of DOTP generated monoethylhexyl terephthalates. Hydrolysis, involving the reaction of DOTP with water, facilitated the cleavage of chemical bonds within the DOTP molecule. Subsequent hydrolysis of this intermediate yielded terephthalic acid.
