A natural rubber degrading bacteria Paenibacillus lautus was isolated from soil samples of a rubber plantation in Sri Lanka. The strain was able to decompose natural rubber latex by adhesively growing on its surface using NR latex as the sole carbon source. The staining test performed using Schiff's reagent confirmed the degradation of NR latex. The Fourier Transform Infrared Spectroscopy further...
A malathion (MLT) degrading strain L19 was isolated from the soil that had been sprayed with MLT for a long time, and strain L19 could grow up with MLT as the sole carbon source. Strain L19 could degrade 87.32% of MLT in medium with 20 mg·L1 MLT after 48h with conditions of 30°C and pH 6.5, and the MLT decomposed was positively correlated with degradation time. Morphological characteristics and 16SrDNA...
Polyacrylamide-degrading fungus was selected from the soil in the chemical plant producting polyacrylamide, and it was named PAMF4. It is capable of utilizing polyacrylamide as sole nitrogen source. According to the morphological characteristics and 18S rRNA sequence analysis, the strain was preliminarily identified as Geotrichum candidum. As the indices with PAMF4 growth and polyacrylamide degradation...
A new phenol-degrading bacterium with high biodegradation activity and high tolerance of phenol, strain B3, was isolated from the coking wastewater of Coking Plant of Shougang in Beijing. The physic-biochemical characteristics as well as 16SrDNA gene sequence analysis were applied to classify the bacteria and its characteristics of degrading phenol. The results showed that the strain B3 was identified...
The occurrence of cyanobacterial water blooms is a world wide concern in environmental health. Microcystin-RR (MC-RR) could be produced by cyanobacterial cells collected from Dianchi Lake and its content was about 0.12 mg/g in cyanobateria samples. A promising bacterial strain of Sphingopyxis sp. USTB-05 we previously isolated was found to have a strong abiLity in the biodegradation of MC-RR extracted...
The pyrolysis oil from lignocellulosic biomass as a renewable resource has been exploited and utilized. Microbial degradation of the pyrolysis oil by several fungi strains was investigated. The results showed that Trichoderma viride, Aspergillus niger, Trichoderma harzianum, Penicillium oxalium and Phanerochaete chrysosporium could grow well using the pyrolysis oil as carbon source, while the growth...
In this paper, the activated sludge which taken from the oxidation ditch of the sewage treatment plant was domesticated for 40d with simulated cooking fumes, and 4 strains of dominant microbes were gained after screened twice, named as ZH-01, HL-03, XJ-021 and BD-55, degradation rates to pollutants from cooking fumes was determined as 60.95%, 68.81%, 65.22%, 74.57% respectively. 4 strains of dominant...
An aerobic bacterial strain Alcaligenes F-3-4 was isolated from an acrylic fiber wastewater. This strain was able to degrade 2,6-di-tert-butylphenol. The bacterium growth and 2,6-DTBP degradation was determined. Result showed, the lag period was extended when increasing the concentration of 2,6-DTBP. At 37°C and at log period, the degrading rate for 100.0 mg/L 2,6-DTBP could reach 86% within 12 d...
A chlorpyrifos-degrading strain of Stenotrophomonas acidaminiphila, lux-β was chosen for research object, and the survival and chlorpyrifos-degrading activity of strain lux-β in the soil with different treatments have been investigated in this study, so as to provide technique support for monitoring the colonization and degrading activity of chlorpyrifos-degrading bacteria in natural environment....
Atrazine is an s-triazine herbicide that has been used widely over 50 years. This has resulted in the contamination of surface water, groundwater and soil. For the bioremediation of atrazine-contaminated environments, we investigated the biodegradation of atrazine and bioremediation of atrazine-contaminated soil by two groups of mixed bacteria (Pseudomonas sp. ADP and Arthrobacter aurescens TC1; Arthrobacter...
Through combination-carrier AP, using the artificial enrichment and accumulation microorganisms on degradation of Persistent Organic Pollutants (POPs) was researched in the Meiliang Bay of Lake Taihu source water. While density of combination-carrier AP was 13.1%, the pilot showed that the effect of degradation of Nitrobenzene was increased as HRT extended. Under the condition of Hydraulic Retention...
A thermophilic oil-degrading bacterial group, named KL6-3 was screened by means of enrichment culture from soil contaminated by heavy oil from Karamay of Xinjiang Oilfield. Its oil degradation rate was up to 48.6% at 45°C and oil concentration of 10g·L-1(data not reported). To evaluate biodegradation to petroleum polluted soil of the KL6-3, the soil samples collected from Karamay supplemented with...
A strain of bacterium, Rhodopseudomonas palustris PSB-1D, which could degrade o-chlorophenol (2-CP), was isolated and screened from shallow sediment in downstream side of the sewage outfall of an insecticide factory. The strain PSB-1D could not utilize 2-CP as the sole carbon source and energy resource. However, it could degrade 2-CP in the presence of co metabolism substrates. Seven kinds of additional...
