Prevention of food poisoning in hospital patients
(Health & Medical Publishing Group, 1974)
Bacteriological investigations of raw and cooked foods and of food handlers in abattoirs, food factories and hospital kitchens show that they are potential sources of food poisoning organisms. The use of reheated (reconstituted) ...
Converting plant biomass to fuels and commodity chemicals in South Africa : a third chapter?
(Academy of Science for South Africa, 2003)
THERE HAVE BEEN TWO DISTINCT CHAPTERS in the history of converting cellulosic biomass to fuels and commodity chemicals in South Africa. The first chapter, from the late 1970s to the early 1990s, involved some of the most ...
Optimized production of bacteriocin ST11BR, generated by Lactobacillus paracasei subsp. paracasei ST11BR isolated from traditional South African beer
(Academy of Science for South Africa, 2005)
Little is known about the production of antimicrobial peptides (bacteriocins) by lactic acid bacteria in traditional South African beer and their inhibition of food spoilage or pathogenic bacteria. In this paper, we report ...
A phylogenetic revision of Penicillium sect. Exilicaulis, including nine new species from fynbos in South Africa
(International Mycological Association, 2016-06-01)
A survey of the fynbos biome in South Africa resulted in the isolation of 61 Penicillium species from Protea repens infructescences, air, and soil samples. Fourteen of these belong to Penicillium sect. Exilicaulis and ...
Construction of industrial Saccharomyces cerevisiae strains for the efficient consolidated bioprocessing of raw starch
(BMC (part of Springer Nature), 2019-08-20)
Background: Consolidated bioprocessing (CBP) combines enzyme production, saccharification and fermentation into a one-step process. This strategy represents a promising alternative for economic ethanol production from starchy ...
Migration of bacteriocins across gastrointestinal epithelial and vascular endothelial cells, as determined using in vitro simulations
(Nature Research (part of Springer Nature), 2019-08-07)
Little is known about the migration of bacteriocins across human cells. In this study, we report on migration of three bacteriocins nisin, plantaricin 423 and bacST4SA across colonic adenocarcinoma (Caco-2) cells and human ...
Emergomyces africanus in soil, South Africa
(Centers for Disease Control and Prevention, 2018-02)
We detected Emergomyces africanus, a thermally dimorphic fungus that causes an HIV-associated systemic mycosis, by PCR in 18 (30%) of 60 soil samples from a wide range of habitats in South Africa. Direct and indirect culture ...
Bacterial diversity and production of sulfide in microcosms containing uncompacted bentonites
Aims: This study examined the diversity and sulfide-producing activity of microorganisms in microcosms containing commercial clay products (e.g., MX-80, Canaprill and National Standard) similar to materials which are ...

(BioMed Central, 2013-12)
This Editorial introduces a special issue from the 20th International Symposium on Alcohol Fuels (ISAF 2013) on alcohol fuels enabling sustainable future development.
Economic risks due to declining water quality in the Breede River catchment
(South African Water Research Commission, 2018-07-03)
Water is a critical resource necessary to support social and economic development. Economic growth and, in particular, the growth of urban and peri-urban areas, however results in declining water quality which threatens ...
