Microbial interactions in drinking water systems
(Stellenbosch : Stellenbosch University, 2004-03)
ENGLISH ABSTRACT: Microorganisms show a tendency to accumulate on surfaces in aqueous environments to form biofilms. Microbial biofilms represent a significant problem in public health microbiology as the development ...
Co-detection of virulent escherichia coli genes in surface water sources
(Public Library of Science, 2015)
McNemar’s test and the Pearson Chi-square were used to assess the co-detection and observed frequency, respectively, for potentially virulent E. coli genes in river water. Conventional multiplex Polymerase Chain Reaction ...
Characterisation and antimicrobial activity of biosurfactant extracts produced by Bacillus amyloliquefaciens and Pseudomonas aeruginosa isolated from a wastewater treatment plant
Biosurfactants are unique secondary metabolites, synthesised non-ribosomally by certain bacteria, fungi and yeast, with their most promising applications as antimicrobial agents and surfactants in the medical and food ...
Variants of lipopeptides and glycolipids produced by Bacillus amyloliquefaciens and Pseudomonas aeruginosa cultured in different carbon substrates
The quantitative and qualitative effect of water immiscible and miscible carbon-rich substrates on the production of biosurfactants, surfactin and rhamnolipids, by Bacillus amyloliquefaciens ST34 and Pseudomonas aeruginosa ...
Geographical distribution, characterisation and evaluation of Saccharomyces cerevisiae strains isolated from South African vineyards in the warmer, inland regions of the Western Cape
(Stellenbosch : Stellenbosch University, 1999-12)
ENGLISH SUMMARY: The natural or spontaneous fermentation of grape must sugars, by yeast that originate from the grapes and winery equipment, to ethanol, carbon dioxide and other minor, but important metabolites, produces ...
Molecular detection of acanthamoeba spp., naegleria fowleri and vermamoeba (hartmannella) vermiformis as vectors for legionella spp. in untreated and solar pasteurized harvested rainwater
(BioMed Central, 2016)
Background: Legionella spp. employ multiple strategies to adapt to stressful environments including the proliferation in protective biofilms and the ability to form associations with free-living amoeba (FLA). The aim of ...
