| 1 | Bacterial degradation of coal discard and geologically weathered coal显示文摘The biodegradation of coal discard is being intensively studied in South Africa in an effort to develop passive methods for the successful revegetation and rehabilitation of waste dumps, to mitigate pollution, and facilitate mine closure. Bacteria were isolated from slurries of coal tailings and diesel-contaminated soil, screened for coal biodegradation competence, characterized, and the colonization and degradation of coal discard and geologically weathered coal investigated using individual isolates and consortia. Ten novel coal-degrading bacterial strains were isolated and characterized, the gene sequences deposited with GenBank, and the (wild-type) strains deposited at Microbial Culture Collection, India. The results from the present work show that bituminous coal discard and geologically weathered coal is used by these isolates as carbon and energy source. Isolated strains and consortia colonized and degraded both coal substrates. Growth rate of the isolates is faster and stationery phase achieved sooner in minimal medium containing geologically weathered coal. This observation suggests that the oxygen-rich weathered coal is a more friable substrate and thus readily colonised and biodegraded. A reduction in mass of substrate is demonstrated for both individual isolates and consortia. The changes in pH and associated media colouration occurred concomitant with formation of humic acid-like (HS) and fulvic acid-like substances (FS) which is confirmed following analysis of these products by FT-IR spectroscopy. It is concluded that preferential metabolism of alkanes from the coal substrates provided the carbon and energy for bacterial growth and transformation of the substrates to HS and FS. | Jacob Taiwo Olawale Oghenekume Gerald Edeki Ashton Keith Cowan | 2020 | International Journal of Coal Science & Technology2020，7，2： | 2 |

| 4 | 满足多功能需要的信号发生器显示文摘我们经常可以听到这样的疑问:“为什么我们花了许多钱购买的仪器却不适用?”,也许,您选择的仪器仅是为满足某一特定用途而没有足够的功能来满足今天发展的需要。 适应性相对于陈旧性而言,这就是为什么当今市场上越来越多的用户偏爱多功能信号发生器的一个原因。多用途产品可节约成本,不但一台仪器可能提供另外两台仪器的功能。 | 赵相珺 Gerald Jacob | 1994 | 国外电子测量技术1994，13，4： | 0 |
