Bacteria as biological control agents of freshwater cyanobacteria: is it feasible beyond the laboratory?

Author: Ndlela, Luyanda L ; Oberholster, Paul J ; Van Wyk, JH ; Cheng, Po Hsun H Date: Dec 2018 Biological control of cyanobacteria is a well-researched area with a central focus on laboratory-scale studies. Numerous reports have been made on algicidal isolates, with bacteria as a major component of the antagonists. The research in this ... Read more
Bacterial control of cyanobacteria

Author: Ndlela, Luyanda L ; Oberholster, Paul J ; Van Wyk, Johannes Date: Aug 2017 With the effects of climate change, harmful algal blooms (HABs) have become a global concern, with serious implications in water scarce countries and vulnerable continents such as Africa. A need exists for low-cost, environmentally feasible ... Read more
Biological control of toxic cyanobacteri

Author: Ndlela, Luyanda L ; Oberholster, Paul J ; Van Wyk, J ; Cheng, Po-Hsun Date: May 2017 With the effects of climate change, harmful algal blooms (HABs) have become a global concern, with serious implications in water scarce countries such as South Africa. There is a specific lack of information in the African continent regarding ... Read more
Biological control of toxic cyanobacteria

Author: Ndlela, Luyanda L ; Oberholster, Paul J ; Van Wyk, J Date: Apr 2016 With the effects of climate change, harmful algal blooms (HABs) have become a global concern, with serious implications in water scarce countries such as South Africa. There is a specific lack of information in the African continent regarding ... Read more
Bulk scale industrial effluent reuse potential in South Africa

Author: Steyn, Maronel ; Walters, Chavon R ; Mathye, Salamina M ; Thwala, Melusi ; Banoo, Ismail ; Ndlela, Luyanda L ; Tancu, Yolanda ; Genthe, Bettina Date: Nov 2021 Rationale: Water scarcity, increased pollution, unprecedented population growth and climate change are collectively driving the need to reuse water with the aim to enhance water security, sustainability, and resilience. It is clear that South ... Read more
Bulk scale industrial effluent reuse potential in South Africa Atlas

Author: Steyn, Maronel ; Walters, Chavon R ; Mathye, Salamina M ; Thwala, Melusi ; Ndlela, Luyanda L ; Tancu, Yolanda ; Lehutso, Raisibe F ; Banoo, Ismail Date: Oct 2021 Globally, responsible and efficient water management is fast becoming a pressing reality for domestic users, agriculture and industry alike. The challenge is therefore to capitalise on the limited water we currently have. Solution: Bulk-scale ... Read more
Evaluation of the probable synergistic toxicity of selected potentiated antiretroviral and antibiotics on some aquatic biomarker organisms

Author: Omotola, EO ; Genthe, B ; Ndlela, Luyanda L ; Olatunji, OS Date: Nov 2023 Environmental effects of active pharmaceutical compounds (APCs) in the environment are not well characterized, hence the need for comprehensive evaluation. This study employed three bioassays using three organisms, namely, Allium cepa, Daphnia ... Read more
Evaluation of wild herbivore faeces from South Africa as a potential source of hydrolytically active microorganisms

Author: Ndlela, Luyanda L ; Schmidt, S Date: Feb 2016 This study assessed faecal matter from three indigenous South African herbivores-zebra, giraffe and impala-as a potential source for hydrolytically active aerobic and facultatively anaerobic bacteria. Herbivore droppings were collected freshly ... Read more
Insights into the ecotoxic impact of diclofenac using Daphnia magna as a model organism

Author: Omotola, EO ; Genthe, Bettina ; Ndlela, Luyanda L ; Olatunji, SO Date: Jun 2023 Residues of pharmaceutical compounds (PCs) are among the groups of contaminants of emerging concerns that have been reportedly detected in the aquatic environment. These compounds are widely distributed in diverse water bodies, thus, necessitating ... Read more
A laboratory based exposure of Microcystis and Oscillatoria cyanobacterial isolates to heterotrophic bacteria

Author: Ndlela, Luyanda L ; Oberholster, Paul J ; Van Wyk, JH ; Cheng, Po Hsun Date: Apr 2019 Biological control of cyanobacteria is a viable means of controlling nuisance bloom occurrences; however the majority of studies done are against Microcystis sp., with a commonly lytic effect caused. Filamentous cyano-bacteria such as ... Read more
Optimisation of surfactant decontamination and pre-treatment of waste chicken feathers by using response surface methodology

Author: Tesfaye, T ; Sithole, Bishop B ; Ramjugernath, D ; Ndlela, Luyanda L Date: Feb 2018 Commercially processed, untreated chicken feathers are biologically hazardous due to the presence of blood-borne pathogens. Prior to valorisation, it is crucial that they are decontaminated to remove the microbial contamination. The present ... Read more
An overview of cyanobacterial blooms occurrences and research in Africa over the last decade

Author: Ndlela, Luyanda L ; Oberholster, Paul J ; Van Wyk, JH ; Cheng, Po-Hsun Date: Dec 2016 Cyanobacterial blooms are a current cause for concern globally, with vital water sources experiencing frequent and increasingly toxic blooms in the past decade. These increases are resultant of both anthropogenic and natural factors, with ... Read more
