Abstract

This study revealed the efficiency of Bacillus subtilis in degrading two textile dyes (disperse red and disperse yellow), the rates of red dye removal when measured after 24, 48, 72 and 96 hours for the concentrations of 50 ppm were 51.67, 67.56, 84.67 and 95.33%, for the concentration 150 ppm were 41.67, 62.67, 80.67 and 89.67%, while for the concentration 300 ppm were 25.67, 42.67, 71.67 and 84.33%. The results of yellow dye removal showed that the concentration of 50 ppm were 49.67, 65.33, 83.33 and 92.67%, for the concentration of 150 ppm were 38.33, 60.33, 77.33 and 87.33%, and for the concentration, 300 ppm were 24, 36.67, 68.33 and 81.67%, when measured after 24, 48, 72 and 96 hours. Results recorded a slight decrease in pH values for all concentrations for each dye during 96 hours. Results also revealed a high reduction of EC and TDS values for both dye concentrations after 96 hours.

枯草芽孢杆菌对两种纺织染料的生物降解

这项研究揭示了枯草芽孢杆菌降解两种纺织染料（分散红和分散黄）的效率，浓度为 50 ppm 的红色染料在 24、48、72 和 96 小时后的去除率分别为 51.67、67.56、84.67 和 95.33%，浓度为 150 ppm 的红色染料在 24、48、72 和 96 小时后的去除率分别为 41.67、62.67、80.67 和 89.67%，浓度为 300 ppm 的红色染料在 24、48、72 和 96 小时后的去除率分别为 25.67、42.67、71.67 和 84.33%。黄色染料去除率结果显示，浓度为 50 ppm 的染料去除率分别为 49.67%、65.33%、83.33% 和 92.67%，浓度为 150 ppm 的染料去除率分别为 38.33%、60.33%、77.33% 和 87.33%，浓度为 300 ppm 的染料去除率分别为 24%、36.67%、68.33% 和 81.67%。结果表明，在 96 小时内，所有浓度的每种染料的 pH 值都略有下降。结果还显示，96 小时后，两种浓度的染料的 EC 值和 TDS 值都有大幅下降。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
