Bacillus-based bionematicides: development, modes of action and commercialisation
Engelbrecht, Gerhard; Horak, Ilze; Jansen van Rensburg, Peet J.; Claassens, Sarina (Taylor & Francis, 2018)Agricultural crops are severely damaged by root-knot nematodes causing extensive financial losses globally. Historically, agrochemicals have been the preferred method to combat these pests; however, threats to humans and ... -
Can a metabolomics-based approach be used as alternative to analyse fatty acid methyl esters from soil microbial communities?
Willers, Clarissa; Jansen van Rensburg, Peet J.; Claassens, Sarina (Elsevier, 2016)Modern high-throughput approaches such as metabolomics, holds promise for investigating microbial communities. This study evaluated the quantitative and qualitative data generation potential of a metabolomics-based approach ... -
Characterising the metabolic differences related to growth variation in farmed Haliotis midae
Venter, Leonie; Loots, Du Toit; Mienie, Lodewyk J.; Jansen van Rensburg, Peet J.; Lindeque, Jeremie Zander (Elsevier, 2018)The South African abalone farming industry is entirely based on Haliotis midae, which has been commercially cultured with great success the last 20 years. Even though abalone are cultivated under identical farming conditions, ... -
The cross-tissue metabolic response of abalone (Haliotis midae) to functional hypoxia
Venter, Leonie; Loots, Du Toit; Mienie, Lodewyk J.; Jansen van Rensburg, Peet J.; Mason, Shayne; Lindeque, Jeremie Z. (The Company of Biologists, 2018)Functional hypoxia is a stress condition caused by the abalone itself as a result of increased muscle activity, which generally necessitates the employment of anaerobic metabolism if the activity is sustained for prolonged ... -
From untargeted LC-QTOF analysis to characterisation of opines in abalone adductor muscle: theory meets practice
Venter, Leonie; Jansen van Rensburg, Peet J.; Loots, Du Toit; Lindeque, Jeremie Zander; Vosloo, Andre (Elsevier, 2017)Abalone have a unique ability to use pyruvate, various amino acids and dehydrogenases, to produce opines as means to prevent the accumulation of NADH during anaerobic conditions. In this study, the theoretical masses, ... -
Obesity and metabolomics: metallothioneins protect against high-fat diet-induced consequences in metallothionein knockout mice
Lindeque, Jeremie Z.; Jansen van Rensburg, Peet J.; Louw, Roan; Van der Westhuizen, Francois H.; Giralt, Mercedes; Hidalgo, Juan (Mary Ann Liebert Inc., 2015)Obesity continues to rise as an alarming global epidemic. System level mechanisms, diagnostics, and therapeutics are sorely needed so as to identify at risk individuals and design appropriate population scale interventions. ... -
Uncovering the metabolic response of abalone (Haliotis midae) to environmental hypoxia through metabolomics
Venter, Leonie; Loots, Du Toit; Mienie, Lodewyk Japie; Jansen van Rensburg, Peet J.; Mason, Shayne; Lindeque, Jeremie Zander (Springer, 2018)Introduction Oxygen is essential for metabolic processes and in the absence thereof alternative metabolic pathways are required for energy production, as seen in marine invertebrates like abalone. Even though hypoxia has ...
