Investigation of alternative carbon sources for the biological treatment of synthetic sulphate-laden water and mine impacted water in a linear flow channel reactor
… sulphate reduction (BSR) offers a sustainable alternative for sulphate removal and is applicable to partially treated AMD as well as circum- neutral, mine-impacted water. Coupled with partial sulphide oxidation, it also has the potential to convert sulphate to elemental sulphur, touching on …

Alternative Carbon Utilization As A Virulence Determinant For Candida Albicans
… to the macrophage phagosome by upregulating alternative carbon utilization processes. The utilization of three alternative carbon sources particularly contribute to <em>C. albicans </em>pathogenesis: carboxylic acids, amino acids, and <em>N</em>-acetylglucosamine. Studied individually, …

Evaluation of gasoline-denatured ethanol as a carbon source for wastewater denitrification
Methanol (MeOH) is a common external carbon source for wastewater denitrification, because of its low cost and low sludge yield. Ethanol (EtOH), on the other hand, is more expensive, but yields higher denitrification rates. This study introduces gasoline-denatured ethanol (dEtOH), which is now …

Microrecycling of Batteries and Carbon-Containing Waste for Manufacturing Different Materials
… are increasingly being considered as a viable alternative, given the limited availability of lithium and the abundance of sodium. Among the components of a battery, graphite has been widely used as the anode material in Li-ion batteries. However, it fails to deliver satisfactory performance in …

Regulation of Alternative Carbon Metabolism In Candida Albicans
… reorganization activating genes involved in alternative carbon metabolism, including the glyoxylate cycle, β-oxidation and gluconeogenesis. Mutations in key enzymes such as ICL1 (glyoxylate cycle) and FOX2 (fatty acid β-oxidation) revealed that alternative carbon metabolic pathways are …

Alumina-modified cobalt catalysts for the Fischer-Tropsch synthesis
In the Fischer-Tropsch process, valuable hydrocarbons are produced using the basic starting materials hydrogen and carbon monoxide, which can be derived from alternative carbon sources such as coal, gas or biomass [1]. Although this process has been studied for almost a century, the effects of the …

Finding Typhoid Mary: Identifying Latent Carriers of Salmonella enterica serovar Typhimurium
… developed a mechanism to utilize acetone as a carbon source to synthesize tricarboxylic acid (TCA) cycle intermediates. This anaplerotic reaction allows organisms to conserve carbon and use alternative carbon sources. This cycle is one way in which bacteria can adapt and survive in an …

Molecular analysis of small RNA and small protein regulation of Escherichia coli stress responses
… but also overrides inducer exclusion allowing alternative carbon sources to be transported and metabolized during stress. We also uncover the regions of PtsG that are required for SgrT regulation. Although the precise nature of glucose-phosphate stress is not well understood, this work …

Semi-biological domino catalysis using acetate- and propionate-producing microbes
… or agriculturally relevant crops as the carbon sources. Hence, sourcing these feedstocks from alternative sustainable carbon sources could contribute to the defossilisation of the chemical industry. Alternative carbon sources, such as carbon dioxide (CO2) and glycerol, both of which can …

The Effect of Select Biological and Environmental Factors on the Horizontal Gene Transfer and Functionality of the TOL Plasmid: A Case Study for Genetic Bioaugmentation
… to degrade and utilize toluene as the sole carbon source even though all of the necessary genes have been successfully transferred. Further investigations have shown that such transconjugants require additional external factors for toluene degradation such as alternative carbon sources. For …
