“…This implies that the ratio of Nitrospira increased with increasing vegetation growth time. Aditiawati et al studied the bacterial community composition in coal mining soil and found Enterobacter and Bacillus were the dominant species [34]. In this study, Bacillus was found in all samples, and the highest proportion was found in the surface soil of NSA.…”

Vegetation restoration is an available way to ameliorate degraded lands. In order to study the response of soil microbes to vegetation restoration in coal mining subsidence areas, the composition and distribution of soil microbes were discussed through three plots: unsubsided area (CA), new subsided area (NSA), and old subsided area (OSA) with different vegetation restoration time in Huabei coal mine. Meanwhile, changes in soil catalase and urease activity were explored and the correlation between soil bacteria, fungi, and environmental factors was analysed. The results demonstrated that Nitrospira was the dominant bacteria in all areas sampled. Microorganisms in the 0–20 cm and 40–60 cm soil layers of OSA had the highest Simpson index, whereas the index in NSA was lowest (at all soil depths). The catalase activity in NSA was significantly higher than that in CA, and there was no significant difference in catalase activity with soil depth, while the urease activity declined gradually with increasing soil depth. The urease activity in the 20–60 cm soil layer of NSA and OSA was significantly higher than that of CA. Furthermore, the distribution of bacteria was mainly affected by soil organic matter, available potassium, available phosphorus, and alkali-hydrolyzable nitrogen, whereas pH and catalase activity mainly affected fungal distribution. These results implied that soil catalase activity in NSA and urease activity in the 20–40 cm soil layer of NSA and OSA were significantly enhanced after vegetation restoration, and that long-term plant restoration could improve soil fertility and soil microbial community diversity in coal mining areas.

“…It's well-known that it pollutes the world. There are various coal mines in Sumatra that might be a source of phenolic pollution [16]. A wide range of microorganisms are capable of degrading a selection of xenobiotics and removing heavy metals simultaneously, and their adaptability is highly sought after in contaminated areas.…”

Millions of tonnes of these chemicals are manufactured each year and a large quantity is determined to be contaminating the environment, making them important worldwide pollutants. The fact that they pollute the environment is a major problem on a worldwide scale. There is a continuing search for bioremediation of these contaminants employing bacteria capable of numerous detoxifications. Analysis of the bacterium yielded a preliminary identification of the organism as Pseudomonas aeruginosa Neni-4. Screening for the capacity of molybdenum-reducing bacteria to decolorize different polyphenols was conducted in this study. Reduction was optimum at pH 6.3 and between 25 and 40 oC. The bacterium used glucose as the best carbon source or molybdenum reduction followed by galactose, 2-ketogluconate, and citrate in decreasing order. Phosphate between 5.0 and 7.5 mM and sodium molybdate between 15 and 20 mM maximally supported reduction. Like earlier Mo-reducing bacteria, a reduction of phosphomolybdate is seen in the absorption spectra of the Mo-blue generated. Heavy metals prevented molybdenum reduction. None of the phenolic compounds can reduce molybdenum when provided as sole carbon sources. In contrast, the bacterium was able to grow on phenol, benzoate, salicylic acid, and catechol, all of which are substances that include phenolic components. A significant bioremediation technology is this bacterium's capacity to metabolise molybdenum and thrive on poisonous phenolics.
