Isolation and characterisation of bioactive compounds from antidesma venosum E.Mey. ex Tul. and euphorbia cooperi N.E.Br. ex A.Berger.
(2018)The need for the discovery of new pharmacologically active compounds is a global priority as new diseases and drug resistance mechanisms are emerging and spreading throughout the world. In the past natural products have ... -
Isolation and characterisation of extended spectrum B-lactamases in South African Klebsiella pneumonia isolates.
(2012)The use of antibiotics and antimicrobial drugs has played a large role in the elimination of many infectious diseases, however the wide spread use of such drugs has given rise to the phenomenon of antimicrobial resistance ... -
Isolation and characterisation of secondary metabolites of two asteraceae species, Artemisia afra and Elytropappus rhinocerotis.
(2009)In this study two medicinal plant species, namely Artemisia afra Jacq. ex. Willd and Elytropappus rhinocerotis Less. (L.f) (= Dicerotamnus rhinocerotis Koekemoer), both belonging to the family Asteraceae, have been ... -
Isolation and characterisation of senescence-related genes in carnations.
(1995)Senescence has been the subject of many studies, with the ultimate goal of increasing longevity of cut flowers, and for insight into the process of ageing. Senescence in the carnation is a complex phenomonen involving ... -
Isolation and characterization of antibiotic(s) produced by bacteria from KwaZulu-Natal soils.
(2010)This work reports the continued search for new antibiotics in the relatively under investigated region of KwaZulu-Natal, South Africa. A soil bacterium designated strain N8 with antibacterial activity against both Gram-positive ... -
Isolation and characterization of carotenoid producing microalgae from KwaZulu-Natal (South Africa).
(2017)Abstract available in PDF file. -
Isolation and characterization of cytotxic compounds from Anthosperum hispidulum and Eriocephalus tenuifolius.
(2008)Cancer is a human tragedy that strikes and kills the lives of our beloved people. With a limited number of effective anticancer drugs from natural resources currently in use, there is a real need for new, safe, cheap and ... -
Isolation and characterization of diaryl ester catabolizing soil fungi.
(2019)Aromatic hydrocarbons are major organic pollutants that can persist in the environment. However, many fungi and yeasts can utilize these compounds as carbon and energy sources under aerobic conditions. Salol and benzyl ... -
Isolation and evaluation of autochthonous microalgae strains for biodiesel production and wastewater treatment.
(2018)The current depletion of global fossil fuel reserves and increasing CO2 emission are generating global climate change concerns hence, the increasing calls for the development of renewable biofuels with low CO2 emission. ... -
Isolation and identification of antibiotic producing microorganisms from natural habitats in the KwaZulu-Natal midlands.
(2001)The search for new antibiotics continues in a rather overlooked hunting ground. In the course of screening for new antibiotic-producing microorganisms, seventy-nine isolates showing antimicrobial activity were isolated ... -
Isolation and identification of antidiabetic compounds from brachylaena discolor DC.
(2017)Abstract available in PDF file. -
Isolation and identification of novel compounds from indigenous plants.
(1993)Abstract available in pdf file. -
Isolation and molecular characterisation of tomato spotted wilt virus (TSWV) isolates occuring in South Africa.
(2006)Tomato spotted wilt virus (TSWV), a Tospovirus, is one of the ten most economically destructive plant viruses worldwide, causing losses exceeding one billion U.S. dollars annually on several crops. In South Africa (SA), ... -
Isolation and screening of freshly isolated bradyrhizobium and rhizobium spp. for multi-host plant growth promotion.
(2016)Biological nitrogen fixation (BNF) is an essential part of sustainable agriculture. Inorganic nitrogenous fertilizers are extensively used in modern, high input agriculture. However, they are expensive, and poorly absorbed ... -
Isolation of a human anti-HIV gp41 membrane proximal region neutralizing antibody by antigen-specific single B cell sorting.
(Plos., 2011)Broadly neutralizing antibodies are not commonly produced in HIV-1 infected individuals nor by experimental HIV-1 vaccines. When these antibodies do occur, it is important to be able to isolate and characterize them to ... -
Isolation of a Monoclonal Antibody That Targets the Alpha-2 Helix of gp120 and Represents the Initial Autologous Neutralizing-Antibody Response in an HIV-1 Subtype C-Infected Individual.
(American Society for Microbiology., 2011)The C3-V4 region is a major target of autologous neutralizing antibodies in HIV-1 subtype C infection. We previously identified a Center for AIDS Program of Research in South Africa (CAPRISA) participant, CAP88, who ... -
Isolation of an acetochlor detoxifying bacterium and cloning of an associated gene.
(1995)A Pseudomonas strain, AI08, which was capable of detoxifying the herbicide acetochlor (2- chloro-N-ethoxymethyl-6'-ethylacet-o-toluide) was isolated from soils. The microbe was isolated using a combination of batch culture ... -
The isolation of antibiotic survivors in mycobacterium tuberculosis using fluorescence activated cell sorting (FACS).
(2016)Abstract available in PDF file. -
Isolation of entomopathogenic gram positive spore forming bacteria effective against coleoptera.
(2009)Fourteen spore-forming bacterial strains were isolated and screened for entomopathogenic activity. Five displayed toxicity towards the common mealworm, Tenebrio molitor L., (Coleoptera: Tenebrionidae). The majority of the ...
