Co-Metabolic Biodegradation of DBP by Paenibacillus sp. S-3 and H-2
Co-metabolic degradation of DBP by two strains was researched because of high degradation efficiency. Meanwhile, the primary degradation products of DBP by strain S-3, strain H-2, and co-metabolism were identified. Enzymatic activities in the DBP degradation were also analyzed.
Co-metabolic biodegradation of DBP by Paenibacillus sp. S-3 and H-2
Abstract Two di-n-butyl phthalate (DBP)-degrading strains, designated as S-3 and H-2, were isolated from DBP-polluted soil and both identified as Paenibacillus sp. When DBP was provided as the sole carbon source, about 45.5 and 71.7 % of DBP (100 mg/L) were degraded by strain S-3 and H-2, respectively, after incubation for 48 h.

- Does the degradation rate of DBP increase with the biomass of yjb3?
- The analysis of relationship between the degradation rate of DBP and the biomass of the strain YJB3 displayed a linear correlation coefficient of 0.7895 (p < 0.01), showing that the DBP degradation rate increased positively with the biomass of the strain YJB3 (Fig. S4).
- Does Bacillus subtilis 3C3 degrade DPP?
- For example, Bacillus subtilis 3C3 obtained from soil can simultaneously degrade DPP, DBP, BBP, and DEP (Navacharoen and Vangnai, 2011). While the strains Bacillus sp. NO11 and NO14 isolated from river sediments can completely degrade DEP, DBP, and DEHP (Chang et al., 2005).
- Is yjb3 a biodegradation pathway for Paes using endophyte?
- Thus, a degradation pathway of DBP by the strain YJB3 was proposed that MBP was formed, followed by PA, and then the intermediates were further utilized till complete degradation. To our knowledge, this is the first study to show the biodegradation of PAEs using endophyte.
- What factors affect DBP degradation?
- The relative ranking of these variables showed that acetate (p = 0.0153), inoculum size (p = 0.0228), temperature (p = 0.0251), and pH (p = 0.0331) were the most significant factors affecting DBP degradation (Table 1).
- How to optimize DBP degradation by yjb3 strain?
- In the present study two-step sequential optimization techniques, Plackett-Burman design (PBD) and response surface methodology (RSM) based on central composite design (CCD) were adopted to optimize the DBP degradation by the strain YJB3.
- Which carbon source is best for enhancing the degradation of DBP?
- Meanwhile, the result of our preliminary experiments showed that acetate was the best carbon source for enhancing the degradation of DBP as compared to other carbon sources including yeast extract, glucose, sucrose, and maltose, and the optimum concentration of acetate was 1.5 g/L (Fig. S2).
