Quantitative Assessment of Human Health Risks Associated with Heavy Metal and Bacterial Pollution in Groundwater from Mankweng in Limpopo Province, South Africa.

Heavy metal and microbial pollution in groundwater raises health concerns due to its adverse effects. This study aimed to assess the health risks associated with heavy metal and bacterial pollution in groundwater in Mankweng. Heavy metals and were detected using inductively coupled plasma mass spectrophotometry and a Colilert system, respectively.

Bioflocculation of pollutants in wastewater using flocculant derived from Providencia huaxiensis OR794369.1.

Background: Water pollution has become a major environmental and health concern due to increasing population and industrialisation. Microbial flocculants are promising agents for treatment of contaminated water owing to their effectiveness, eco-friendliness, and high biosafety levels. In this study, culture conditions of Providencia huaxiensis OR794369.

Antimicrobial, antioxidant and cytotoxic activities of the leaf and stem extracts of Carissa bispinosa used for dental health care.

Background: Carissa bispinosa (L.) Desf. ex Brenan is one of the plants used traditionally to treat oral infections.

Virulence and Antimicrobial Resistance Profiling of Serovars Recovered from Retail Poultry Offal in KwaZulu-Natal Province, South Africa.

As poultry organ meat is widely consumed, especially in low- and middle-income countries, there is reason to investigate it as a source of infections in humans. Consequently, the aim of this study was to determine the prevalence, serotypes, virulence factors and antimicrobial resistance of isolated from chicken offal from retail outlets in KwaZulu-Natal, South Africa. Samples ( = 446) were cultured for the detection of using ISO 6579-1:2017.

Chemical Profile, Antioxidant and Antibacterial Activities, Mechanisms of Action of the Leaf Extract of Mill.

Mill's extracts have been explored for antibacterial and antioxidant efficacies. However, there is limited information on its chemical composition and mechanism of action. The purpose of this study was to assess the chemical composition, antibacterial and antioxidant activities and mechanism of the whole leaf extract of Mill.

Bioprospecting of endophytic actinobacterium associated with Aloe ferox mill for antibacterial activity.

Background: The emergence of drug resistance among pathogens has resulted in renewed interest in bioprospecting for natural microbial products.

Methods: This study aimed to bioprospecting endophytic actinobacterium associated with Aloe ferox Mill for its antibacterial activity. Endophytic actinomycetes were isolated from the gel of A.

Isolation and Optimisation of Culture Conditions for a Marine Bioflocculant-Producing Bacterium and Application of Its Bioflocculant in Wastewater Treatment.

The application of bioflocculants has become an alternative to that of chemical flocculants in wastewater treatment due to their environmental friendliness and non-toxic effects. This study aimed at isolating a bioflocculant-producing bacterium from marine water, optimisation of its culture conditions, and investigation of the removal efficiency of its bioflocculant on pollutants in wastewater. The bacterium was identified by 16S rRNA gene analysis.

Antimicrobial Resistance, Enterotoxin and Gene Profiles of Associated with Beef-Based Protein Sources from KwaZulu-Natal Province, South Africa.

Annually, approximately 23,000 cases of food poisoning by enterotoxins are reported worldwide. The aim of this study was to determine the occurrence and characterize on beef and beef products in South Africa. Organ meats ( = 169), raw processed meat ( = 110), raw intact ( = 53), and ready-to-eat meats ( = 68) were obtained from 25 retail outlets.

Production and Characterization of a Bioflocculant from MH545928.1 and Its Application in Wastewater Treatment.

A variety of flocculants have been used to aggregate colloidal substances. However, recently, owing to the adverse effects and high costs of conventional flocculants, natural flocculants such as microbial flocculants are gaining attention. The aim of the study was to produce and characterize a bioflocculant from MH545928.

Isolation of endophytic bacteria from the leaves of Anredera cordifolia CIX1 for metabolites and their biological activities.

Background: Endophytes, especially those that are found from ethnopharmacologically noteworthy medicinal plants have attracted attention due to their diverse bioactive metabolites of pharmacological importance.

Methods: This study aimed at isolating endophytic bacterium from the leaves of Anredera cordifolia CIX1 for its bioactive metabolites. The endophytic isolates were identified by 16S rRNA sequence and investigated for antibiotic sensitivity using different antibiotics.

Removal of Pollutants in Mine Wastewater by a Non-Cytotoxic Polymeric Bioflocculant from HCB2.

Bioflocculation is a physicochemical technique often employed to efficiently remove colloidal water pollutants. Consequently, in this study, a bioflocculant was produced, characterised and applied to remove pollutants in mine wastewater. The maximum flocculation activity of 92% was recorded at 30 °C, pH 9.
