Oberholster, Paul Johan; Botha, Anna-Maria; Muller, K.; Cloete, T.E. (Thomas Eugene), 1958- (Academic Journals, 2005-05)Molecular marker analysis is becoming increasingly capable of identifying informative genetic variation. Amplified fragment length polymorphism markers (AFLPs) are among the recent innovations in genetic marker technologies, ...

Nevondo, T.S.; Cloete, T.E. (Thomas Eugene), 1958- (Water Research Council, 1999-04)Water contaminated with microbiological and chemical constituents can cause a variety of diseases. Water intended for human consumption should be safe, palatable and aesthetically pleasing. Water sources have different ...

Gumbo, Jabulani Ray; Ross, Gina; Cloete, T.E. (Thomas Eugene), 1958- (Academic Journals, 2008-12-29)Freshwater resources are now threatened by the presence and increase of harmful algal blooms (HAB) all over the world. The HABs are sometimes a direct result of anthropogenic pollution entering water bodies, such as ...

Coetser, S.E.; Pulles, W.; Heath, R.G.M.; Cloete, T.E. (Thomas Eugene), 1958- (Springer Verlag, 2006)The production of acid mine drainage (AMD) containing high amounts of sulfate, heavy metals and low pH is of increasing concern. AMD is highly corrosive and results in economic and environmental problems. Organic electron ...

Cloete, T.E. (Thomas Eugene), 1958-; Smith, Z.; Saayman, Gert (Water Research Council, 1999-07)In this study, a water cooling tower was used as a low-rate biofilm reactor for treating municipal wastewater. The performance of the system was evaluated at three different flow rates. The biofilm reactor gave the best ...

Madoroba, Evelyn; Steenkamp, Emma Theodora; Theron, Jacques; Scheirlinck, Ilse; Cloete, T.E. (Thomas Eugene), 1958-; Huys, Geert (Elsevier, 2011)Ting is a spontaneously fermented sorghum food that is popular for its sour taste and unique flavour. Insight of the microbial diversity and population dynamics during sorghum fermentations is an essential component of the ...

Cloete, T.E. (Thomas Eugene), 1958-; Westaard, D.; Van Vuuren, S.J. (Elsevier, 2003)Biofouling in pipelines is a function of the inner roughness of the specific piping material that is used in distribution systems and the concomitant biofilm formation. To test the effect of velocity on the growth of ...

Oberholster, Paul Johan; Botha, Anna-Maria; Cloete, T.E. (Thomas Eugene), 1958- (Blackwell, 2007-06)This paper describes the results of the investigation of a shallow urban lake before, and a second year after, restoration to determine the effects of aeration and bottom-sediment removal on the trophic state and environmental ...
-
Cloete, T.E. (Thomas Eugene), 1958-; De Bruyn, E.E. (Engela Elizabeth) (Springer, 2001-05)The importance of sulfate-reducing bacteria (SRB) in nature has been widely recognized for many years. However, little is known about the ecology of SRB. The problem has been detecting, classifying, and quantifying these ...

Thantsha, Mapitsi Silvester; Cloete, T.E. (Thomas Eugene), 1958- (Water Research Council, 2006-04)Microbial biofilms are problematic in industrial environments where large areas of submerged surfaces are exposed to relatively high nutrient fluxes, providing niches for the formation of copious surface-associated growth. ...

Jachlewski, Silke; Botes, Marelize; Cloete, T.E. (Thomas Eugene), 1958- (Water Research Council, 2013-01)The effect of ultrasound on the growth of M. aeruginosa confirmed to contain gas vacuoles and on a laboratory culture with no gas vacuoles was investigated. Both cultures were treated continuously for 9 d with an ultrasonic ...
-
Maila, Mphekgo P.; Cloete, T.E. (Thomas Eugene), 1958- (Springer, 2005-09)In this study, we evaluated the heterotrophic microbial communities colonising stone ballasts at diesel depots. The number of bacteria (both total culturable heterotrophic bacteria and hydrocarbon-degrading bacteria) was ...

Maila, Mphekgo P.; Randima, P.; Surridge-Talbot, A.K.J. (Angela Karen Joanna); Dronen, K.; Cloete, T.E. (Thomas Eugene), 1958- (Elsevier, 2005-01)In this study, we evaluated the hydrocarbon removal efficiency and microbial diversity of different soil layers. The soil layers with high counts of recoverable hydrocarbon degrading bacteria had the highest hydrocarbon ...
