  • Research and development of biodegradation disposal for SBS (Sugi Bark Sorbent)

    The research on the practical applications of SBS (Sugi Bark Sorbent) which was initiated in 1997 realized a waste material recycled product using 100% natural materials with reduced environmental loads which is comparable to commonly used petroleum products in terms of performance and cost, and reached the stage of commercial production in 2000. For the purpose of reducing total environmental loads in the oil recovery, we investigated biodegradation treatment as a disposal method of SBS after use (after adsorbing oil). It was confirmed that the oil content was reduced from 10000 ppm to 2000-5000 ppm after 1 to several week-period in a biodegradation experiment using Bunker C in the bark compost.

  • Effects of Pyridine and Methanol on the Biodegradation of 2-methylpyridine by Activated Sludge under Denitrifying Conditions

    Lab-scale batch experiments were conducted to investigate the biodegradation of 2-methylpyridine as sole carbon source under denitrifying conditions. Moreover, effects of pyridine and methanol on the biodegradation of 2-methylpyridine were also studied. Under denitrifying conditions, 2-methylpyridine of 100 mg/L was degraded in 13 h as sole carbon source. When pyridine was used as co-substrate with 2-methylpyridine, 2-methylpyridine degradation was inhibited, and pyridine was degraded prior to 2-methylpyridine. On the contrary, methanol promoted the degradation of 2-methylpyridine.

  • Natural biodegradation of phenolic compounds in groundwater

    A combination of field data and theoretical approaches is used to assess the natural attenuation and status of a complex plume of phenolic compounds (phenol, cresols, xylenols) in a deep, consolidated, UK Permo-Triassic sandstone aquifer. Biodegradation on of the phenol at compounds at concentrations up to 12 500 mg • L−1is occurring under aerobic, NO3−-reducinq Mn/Fe-reducing, SO42−-reducing and methanogenic conditions in the aquifer, with the accumulation of inorganic and organic metabolites in the plume. An electron and carbon balance for the piume suqqests that only 6% of the source term has been degraded in 50 years. The residual contaminant mass in the plume significantly exceeds estimates of electron acceptor inputs, indicating that the plume will grow. Two detailed vertical profiles through the plume show that contaminant distributions are controlled more by source history than by biodegradation processes. Microbiological and mass balance studies show that biodegradation is greatest at the plume fringe where contaminant concentrations are diluted by transverse mixing. Active bacterial populations exist throughout the plume but biodegradation is inhibited in the plume core by high contaminant concentrations. Stable isotope studies show that SO42−-reduction is particularly sensitive to contaminant concentration. The aquifer is not oxidant-deficient but natural attenuation of the phenolic compounds in this system is limited by toxicity from the pollutant load and the bioavailability of electron acceptors. Natural attenuation of these contaminants will increase only after increased dilution of the plume.

  • Influence of Rhamnolipid on the Treatment of Diesel Oil Contaminated Wastewater

    The influence of rhamnolipid on the emulsification and the biodegradation of diesel oil contaminated wastewater were investigated in this paper. It was found that the addition of rhamnolipid influenced positively the emulsification and the biodegradation efficiency of diesel oil contaminated wastewater. And the effect of rhamnolipid on parameters of lipopolysachharide (LPS) release, cell surface hydrophobicity and cell growth of isolates A1 and A2 (both are gram negative stains) were conducted respectively in order to reveal the influence of rhamnolipid on the biodegradation of diesel oil contaminate wastewater. The results demonstrated that the addition of rhamnolipid caused the release of LPS from the outer membrane of both isolates A1 and A2. And the cell surface of both isolates A1 and A2 becomes more hydrophobic upon the addition of rhamnolipid. This contributed to the increased association of cells with hydrophobic substrate diesel oil resulting in increased biodegradation rate. Go with LPS release and increased hydrophobic of isolates A1 and A2 was the increase in the growth rate on the substrate of diesel oil. And the influence of rhamnolipid on LPS release was different for isolates A1 and A2 used in this study. Isolate A1 released more proportion of LPS than that of isolate A2 upon the addition of rhamnolipid with diesel oil wastewater as substrate.

  • An environmentally friendly photoresist and ashing residue remover for Cu/low-k devices

    Developed an effective removal solvent for photoresist and its ashing residue for use in copper wire/low-dielectric interlayer devices that significantly lowers the risk of harming the environment. The inhibition of Cu corrosion is very important in these devices, and benzotriazole (BTA, C/sub 6/H/sub 5/N/sub 3/) is usually used as the corrosion inhibitor. However, BTA creates mutagenicity and biodegrades poorly. We investigated several typical heterocyclic nitrogen compounds such as Cu inhibitor to replace BTA and studied their optimum compositions. We found that uric acid (C/sub 5/N/sub 4/O/sub 3/) was the best corrosion inhibitor for Cu. Moreover, this remover which is composed mainly of amino alcohol, uric acid, and H/sub 2/O can be applied to low-k films by optimizing its H/sub 2/O ratio. It not only effectively removes the ashing residue on Cu/low-k devices, but also effectively reduces the environmental impact because the rinse wastewater containing remover can be completely treated at the fabrication site with ordinary biological processes.

  • The Influences of Tween60 and Rhamnolipid on the Bioremediation of n-Hexadecane

    The influences of adding Tween60 and rhamnolipid on n-hexadecane biodegradation and cell surface characteristics such as cell surface hydrophobicity (CSH) and lipopolysaccharide (LPS) release for two strains of Pseudomonas and Sphingomonas were investigated. The results showed that the additions of Tween60 and rhamnolipid have different effects on the strains of Pseudomonas and Sphingomonas as these two strains degrade n-hexadecane by different modes. The addition of rhamnolipid has a positive influence on the biodegradation of n-hexadecane for both the strains of the Pseudomonas and Sphingomonas. While the addition of Tween60 showed inhibition on the n-hexadecane biodegradation for both the strains of the Pseudomonas and Sphingomona. It could found that the addition of rhamnolipid could enhance the LPS release and increase the CSH for both of two strains, which can cause the sell surface of two strains of Pseudomonas and Sphingomona to become more hydrophobic, so increase the direct contact between the bacteria cell to the hydrocarbons. For the strain of Pseudomonas, the addition of Tween60 has no evident influence on the LPS release and has slightly effect on CSH. And the addition of Tween60 changed the LPS release to the supernatant very slightly and decreased the CSH of strain Sphingomonas dramatically.

  • Study on enhanced treatment of sewage from channel discharge with enzyme

    This research studied enhanced treatment of sewage from channel discharge with enzyme and the effect of enzyme-biofilm process on the treatment of sewage from channel discharge, and investigated the changes of removal rates of the main pollution indexes at different hydraulic retention time (HRT) to ensure the optimal HRT. Meanwhile, compared the difference between the laboratory developed compounded enzyme and the foreign composite enzyme to provide the basis for the use of enzyme in future. The research results indicated that enzyme had the good promotion effect on the removal of the pollution indexes. With the increase of HRT, the removal rates of COD<sub>Cr</sub> and ammonia nitrogen were on the rise. However, when HRT exceeded 10h, the increases of the removal rates of COD<sub>Cr</sub> and ammonia nitrogen became slow, so the optimal HRT was about 10h. Furthermore, the promoting effect of the compounded enzyme was equivalent to that of the composite enzyme for biofilm process, and the compounded enzyme could come into use instead of the composite enzyme.

  • Effect of pyrene contamination on soil microbial biomass and community structure using PLFA analysis

    Phospholipid fatty acid (PLFA) can be used as biological marker of microbial biomass and community structure. In this study PLFA analysis was used on soil microbial diversity with pyrene added The results showed that in the short term, low concentrations of pyrene had no significant effect on Bac-PLFA and Fun-PLFA, while high concentration pyrene showed inhibition effect. It also revealed that every sample, after long-term treatment, showed inhibition; meanwhile the Fun-PLFA, compared with the Bac-PLFA, was more sensitive to pyrene. It was found that the effect G<sup>-</sup>/G<sup>+</sup>-PLFA had on pyrene first increased and then decreased with the increasingly higher concentration of pyrene. The principal component analysis of PLFA showed that short-term treatment with low concentrations of pyrene did not have a significant effect on soil microbial community structure, while short-term and long-term treatment with high concentrations had a significant impact on soil microbial community structure.
