The Ideal

Ngoc Linh ginseng (Panax vietnamensis Ha et Grushv.) is an endemic species in Vietnam and was discovered at the Ngoc Linh mountain (Kon Tum/Quảng Nam). Investigations showed that the soil with a thick layer of humus was the ideal condition for growth and development of Ngoc Linh ginseng. Therefore research on microbial flora as well as cellulose-degrading bacteria in ginseng soil may elucidate factors contributing to acclimatized cultivation of this ginseng in Vietnam. From the soil sample with cultivated Ngoc Linh ginseng in Quang Nam, five bacteria strains with cellulose-degrading activities were isolated (QN1, QN2, QN3, QN4, QN5 with respectively hydrolyzed CMC halos diameters of 10, 11, 22, 7, 22 mm) with cellulase activities of 1,31; 1,23; 2,99; 0,99; 2,51 U/ml. The combination of 16S rRNA gene sequences and cultured/biochemical characteristics of the bacteria showed that the five bacteria strains was classified to be Pseudomonas sp. QN1; Pseudomonas sp. QN4; Bacillus sp. QN2; Bacillus sp. QN3; Roseomonas sp. QN5.

Abstract As a step toward bioaugmentation of coking wastewater treatment 45 bacteria strains were isolated from the activated sludge of a coking wastewater treatment plant (WWTP). Three strains identified as Bacillus cereus, Pseudomonas synxantha, and Pseudomonas pseudoaligenes exhibited high dehydrogenase activity which indicates a strong ability to degrade organic matter. Subsequently all three strains showed high naphthalene degradation abilities. Naphthalene is a refractory compound often found in coking wastewater. For B. cereus and P. synxantha the maximum naphthalene removal rates were 60.4% and 79.8%, respectively, at an initial naphthalene concentration of 80 mg/L, temperature of 30 °C, pH of 7, a bacteria concentration of 15% (V/V), and shaking speed of 160 r/min. For P. pseudoaligenes, the maximum naphthalene removal rate was 77.4% under similar conditions but at 35 °C.

Abstract Twenty-three hydrocarbon-degrading bacteria strains were isolated from gas station leaking-contaminated groundwater located in the Southern Amazon, Brazil. Based on hydrocarbon (diesel, hexadecane, benzene, toluene and xylene) degradation ability, two strains were selected for further study. The amplification and sequencing of the 16S rRNA gene showed that these two strains belonged to the genus Bacillus (Bacillus sp. L26 and Bacillus sp. L30). GC-MS analysis showed that strain L30 was the most effective in degrading n-alkane (C10-C27) from diesel after 7 days of cultivation in mineral medium. Both strains produced biosurfactants and showed emulsification activity, specially the strain L30. Alkane hydroxylase gene (group III), which is important for alkane biodegradation, was present in strains. As a result, this study indicated that these bacteria could have promising applications in hydrocarbon bioremediation.
