Utilization by bacteria oxidation products of coal substance.

Rapid Batch Characterization of Coal Utilization By-Products

Many leaching methods have been used for various purposes by research groups, industries and regulators, but there is still a need for a simple yet comprehensive approach to leaching coal utilization by-products (CUB) and other granular materials. A serial batch characterization method has been developed at the National Energy Technology Laboratory that can be completed in 2-3 days to serve as ...

Utilization of Coal Combustion By-Products and Green Materials for Production of Hydraulic Cement

Phosphonate utilization by bacteria.

Bacteria able to use at least one of 13 ionic alkylphosphonates of O-alkyl or O,O-dialkyl alkylphosphonates as phosphorus sources were isolated from sewage and soil. Four of these isolates used 2-aminoethylphosphonic acid (AEP) as a sole carbon, nitrogen, and phosphorus source. None of the other phosphonates served as a carbon source for the organisms. One isolate, identified as Pseudomonas put...

Strontium isotope study of coal utilization by-products interacting with environmental waters.

Sequential leaching experiments on coal utilization by-products (CUB) were coupled with chemical and strontium (Sr) isotopic analyses to better understand the influence of coal type and combustion processes on CUB properties and the release of elements during interaction with environmental waters during disposal. Class C fly ash tended to release the highest quantity of minor and trace elements...

Utilization of bacteriocin-producing bacteria in dairy products

Lactic acid bacteria have been used since ancient times for food preparation and for bio-conservation by fermentation. Selected strains are capable of producing antimicrobial peptides bacteriocins, which can be natural preservatives, especially in products with short shelf lives. The present study is focused on inhibitory effects of the bacteriocin-producing bacteria strains Enterococcus faeciu...
