Biofertilizers and sustainable agriculture: exploring arbuscular mycorrhizal fungi
(SpringerSpringer, 2017)Worldwide agricultural food production has to double in 2050 so as to feed the global increasing population while reducing dependency on conventional chemical fertilizers plus pesticides. To accomplish this objective, there ... -
Biofilm formation in surface and drinking water distribution systems in Mafikeng, South Africa
(Academy of Science of South Africa, 2014)Poor quality source water and poorly treated reused wastewater may result in poor quality drinking water that has a higher potential to form biofilms. A biofilm is a group of microorganisms which adhere to a surface. We ... -
Biofuel production from spent coffee grounds via lipase catalysis
(Taylor & Francis, 2018)Lipases namely Mucor miehei, Pseudomonas cepacia, Rhizopus delemar, Geotrichum candidum, Candida rugosa, Porcine pancreas-II, Pseudomonas fluorescence, and Candida antarctica lipase-B (Novozyme-435) were employed for ... -
Biofuels from spent coffee grounds: comparison of processing routes
(Taylor & Francis, 2020)Bulk fuel was produced from spent coffee grounds (SCG) using different oil extraction and fuel production methods. The highest oil yield (30.2%) and energy efficiency (50%) from continuous hydrothermal liquefaction (CHTL) ... -
Biogenesis, biologic function and clinical potential of exosomes in different diseases
(MDPI, 2020)Exosomes are extracellular vesicles (EVs) belonging to the nanovesicles family that function as signaling molecules between cells. After their first description in the late 1960s, interest in their potential as a research ... -
Bioimaging of Pb and STIM1 in mice liver, kidney and brain using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and immunohistochemistry
(Elsevier, 2020)Lead (Pb) pollution is one of the most serious environmental problems and has attracted worldwide attention. Pb causes hematological, central nervous system, as well as renal toxicity, and so on. Although many investigations ... -
A bioinformatics pipeline for rare genetic diseases in South African patients
(ASSAf, 2019)The research fields of bioinformatics and computational biology are growing rapidly in South Africa. Bioinformatics pipelines play an integral part in handling sequencing data, which are used to investigate the aetiology ... -
Biological activity of traditional medicinal plants used against lymphatic filariasis in the eastern Free State
(Elsevier, 2017)For centuries medicinal plants have been used for treatment of various diseases. Most frequently, the majority of people in the eastern Free State depend on traditional medicinal plants for their daily health care due to ... -
Biological control of the root-knot nematode Meloidogyne incognita on tomatoes and carrots by plant growth-promoting rhizobacteria
(Springer, 2019)In the current study 27 plant growth-promoting rhizobacteria (PGPR) strains were screened for biocontrol activity against Meloidogyne incognita on 6-week old carrot seedlings that were inoculated with a suspension of J2 ... -
Biological crusts of serpentine and non-serpentine soils from the Barberton Greenstone Belt of South Africa
(Springer, 2017)Climate and geography can influence biological soil crust (BSC) community composition, but local heterogeneity in variables such as soil characteristics or microclimate gradients can also impact cryptogamic diversity. Heavy ... -
Biological reduction of COD and sulphate by SRB in anaerobic moving bed biofilm reactor under high metal loading conditions
(EARET, 2018)The performance of an anaerobic moving bed biofilm reactor (MBBR) containing AnoxKaldnesTM K5 model for the treatment of raw acid mine drainage (AMD) was investigated for the reduction of sulphate and chemical oxygen ... -
Biological toxicity estimates show involvement of a wider range of toxic compounds in sediments from Durban, South Africa than indicated from instrumental analyses
(Elsevier, 2018)The toxic equivalences (TEQs) of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) from sediment of aquatic systems in Durban, South Africa were determined in two ways: 1) TEQs of PAHs and PCBs ... -
Biological, ionizing and ultraviolet radiation and electrochemical degradation of chlorpyrifos pesticide in aqueous solutions
(ESG, 2014)Laboratory experiments were carried out on the effect of the electrochemical degradation, biological removal, ultraviolet and ionizing radiation of chlorpyrifos (O,O-Diethyl O-3,5,6-trichloropyridin-2-yl phosphorothioate) ... -
Biology and performance of two indigenous larval parasitoids on Tuta absoluta (Lepidoptera: Gelechiidae) in Sudan
(Taylor & Francis, 2018)Tuta absoluta is an alien invasive pest in Sudan. Since it was detected in the country, the pest continues to cause major tomato losses. Alarmed by its devastating nature and the speed of spread, tomato growers resorted ... -
