Evaluation of microbial diversity of different soil layers at a contaminated diesel site

Author: Maila, MP ; Randima, P ; Surridge, K ; Dronen, K ; Cloete, TE Date: Jan 2005 In this study, the hydrocarbon removal efficiency and microbial diversity of different soil layers is evaluated. The soil layers with high counts of recoverable hydrocarbon degrading bacteria had the highest hydrocarbon removal rate compared ... Read more
Examination of the behaviour of escherichia coli in biofilms established in laboratory- scale units receiving chlorinated and chloraminated water

Author: Momba, MNB ; Cloete, TE ; Venter, SN ; Kfir, R Date: Sep 1999 Groundwater was treated with chlorine and chloramine to study the incorporation and survival of Escherichia coli (E. coli) in developing biofilms in laboratory-scale units. Membrane filter and standard spread plate procedure were used to ... Read more
Formation of an interpolymer complex in supercritical carbon dioxide and its application in the encapsulation of probiotics

Author: Moolman, S ; Labuschagne, Philip W ; Thantsha, MS ; Van der Merwe, TL ; Cloete, TE Date: 27 Feb 2006 Traditional encapsulation methods present difficulties for sensitive actives such as probiotics, due to exposure to water/solvents, heat, oxygen, etc. The authors present a novel encapsulation technology utilising the formation of an interpolymer ...

Germination of Lepidium sativum as a method to evaluate polycyclic aromatic hydrocarbons (PAHs) removal from contaminated soil

Author: Maila, MP ; Cloete, TE Date: 2002 The sensitivity of Lepidium sativum germination to polycyclic aromatic hydrocarbons (PAHs) was investigated in soil(s) artificially and historically contaminated with mixtures of PAR The level of germination of L. sativum decreased with ... Read more
Microbial community diversity as a potential bioindicator of AMD and steel plant effluent in a channelled valley bottom wetland

Author: Staebe, K ; Botes, M ; Madlala, Tebogo E ; Oberholster, Paul J ; Cloete, TE Date: Dec 2018 Freshwater resources in semi-arid countries are under constant threat from pollution. One of the major pollutants is acid mine drainage (AMD), which not only lowers the pH of the water, but contains high sulphuric acid and high metal ... Read more
Multispecies and monoculture rhizoremediation of polycyclic aromatic hydrocarbons (PAHs) from the soil

Author: Maila, MP ; Randima, P ; Cloete, TE Date: 2005 In this study, the authors investigated the potential of multispecies rhizoremediation and monoculture rhizoremediation in decontaminating polycyclic aromatic hydrocarbon (PAH) contaminated soil. Plant-mediated PAH dissipation was evaluated ... Read more
Novel encapsulation method for probiotics using an interpolymer complex in supercriticial carbon dioxide

Author: Moolman, FS ; Labuschagne, Philip W ; Thantsha, MS ; Van Der Merwe, TL ; Rolfes, H ; Cloete, TE Date: Oct 2006 The CSIR has developed a novel scCO2-based encapsulation technology utilizing interpolymer complex formation to improve the barrier properties of the polymer system. In this paper the auhtors report some results obtained in the application ... Read more
Overview of biofilm formation in distribution systems and its impact on the deterioration of water quality

Author: Momba, MNB ; Kfir, R ; Venter, SN ; Cloete, TE Date: Jan 2000 The impact of biofilms present in water distribution systems on the microbial quality of potable water is reported in this review. The issues covered include the composition of biofilms, factors governing their formation and the effect and ... Read more
Probiotics: What we know and what we need to know

Author: Moolman, FS ; Cloete, TE ; Thantsha, MS Date: Nov 2005 Prebiotics is a non-digestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon (Roberfroid, 1998; Theuer et al., 1998; Young, 1998; ...

Survival of B. longum Bb-46 in simulated gastrointestinal fluids

Author: Thantsha, MS ; Cloete, TE ; Moolman, FS ; Labuschagne, Philip W Date: Jan 2009 Gastric acidity is the main factor affecting viability of probiotics in the gastrointestinal tract (GIT). This study investigated the survival in simulated gastrointestinal fluids of Bifidobacterium longum Bb-46 encapsulated in interpolymer ... Read more
Use of biological activities to monitor the removal of fuel contaminants - perspective for monitoring hydrocarbon contamination: A review

Author: Maila, MP ; Cloete, TE Date: Jan 2005 Soil biological activities are vital for the restoration of soil contaminated with hydrocarbons. Their role includes the biotransformation of petroleum compounds into harmless compounds. In this paper, the use of biological activities as ... Read more
