Abstract
Abstract In this investigation, samples of mining dolomite wastes were collected from Abu Tartur phosphate mines, Egypt. The samples were thermally decomposed to MgO/CaO mixture as evidenced by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The MgO/CaO combination mixture was utilized in this study as an antibacterial agent against Bacillus cereus, Staphylococcus aureus, and Staphylococcus epidermidis. Antibacterial experiments have revealed that the MgO/CaO combination was more effective against Bacillus cereus, Staphylococcus aureus, and Staphylococcus epidermidis. For the three bacterial strains, the minimum inhibitory concentration (MIC) of the tested mixture was found to be 1.0 µg/mL. Acridine Orange pictures, which helped to explain the high occurrence of dead cells, and were utilized effectively to record the effect of MgO/CaO, which was employed in this investigation on the bacterial growth. Taking into consideration, MgO/CaO combination was found to be very interesting candidate material for bacterial disinfection due to its simplicity of synthesis, low cost, low release rate, and as excellent antibacterial activity.
期刊介绍:
Geomicrobiology Journal is a unified vehicle for research and review articles in geomicrobiology and microbial biogeochemistry. One or two special issues devoted to specific geomicrobiological topics are published each year. General articles deal with microbial transformations of geologically important minerals and elements, including those that occur in marine and freshwater environments, soils, mineral deposits and rock formations, and the environmental biogeochemical impact of these transformations. In this context, the functions of Bacteria and Archaea, yeasts, filamentous fungi, micro-algae, protists, and their viruses as geochemical agents are examined.
Articles may stress the nature of specific geologically important microorganisms and their activities, or the environmental and geological consequences of geomicrobiological activity.
The Journal covers an array of topics such as:
microbial weathering;
microbial roles in the formation and degradation of specific minerals;
mineralization of organic matter;
petroleum microbiology;
subsurface microbiology;
biofilm form and function, and other interfacial phenomena of geological importance;
biogeochemical cycling of elements;
isotopic fractionation;
paleomicrobiology.
Applied topics such as bioleaching microbiology, geomicrobiological prospecting, and groundwater pollution microbiology are addressed. New methods and techniques applied in geomicrobiological studies are also considered.
