Antibacterial activities of bacteria isolated from the marine sponges Isodictya compressa and Higginsia bidentifera collected from Algoa Bay, South Africa
Matobole, Relebohile Matthew; van Zyl, Leonardo Joaquim; Parker-Nance, Shirley; Davies-Coleman, Michael T.; Trindade, Marla (MDPI AG, 2017)Due to the rise inmulti-drug resistant pathogens and other diseases, there is renewed interest in marine sponge endosymbionts as a rich source of natural products (NPs). The South African marine environment is rich in ... -
Diversity of dsDNA viruses in a South African hot spring assessed by metagenomics and microscopy
Zablocki, Olivier; van Zyl, Leonardo Joaquim; Kirby, Bronwyn; Trindade, Marla (MDPI, 2017)The current view of virus diversity in terrestrial hot springs is limited to a few sampling sites. To expand our current understanding of hot spring viral community diversity, this study aimed to investigate the first ... -
Factors influencing pigment production by halophilic bacteria and its effect on brine evaporation rates
Silva-Castro, Gloria Andrea; Moyo, Anesu Conrad; Khumalo, Londiwe; van Zyl, Leonardo Joaquim; Petrik, Leslie F.; Trindade, Marla (Wiley, 2018)The disposal of reject brine, a highly concentrated waste by-product generated by various industrial processes, represents a major economic and environmental challenge. The common practice in dealing with the large ... -
Genomic characterization of a prophage, Smhb1, that Infects Salinivibrio kushneri BNH isolated from a Namib Desert saline spring
Olonade, Israel; van Zyl, Leonardo Joaquim; Trindade, Marla (MDPI, 2021)Recent years have seen the classification and reclassification of many viruses related to the model enterobacterial phage P2. Here, we report the identification of a prophage (Smhb1) that infects Salinivibrio kushneri BNH ... -
Impact of metagenomic DNA extraction procedures on the identifiable endophytic bacterial diversity in Sorghum bicolor (L. Moench)
Maropola, Mapula Kgomotso Annah; Ramond, Jean-Baptiste; Trindade, Marla (Elsevier, 2015)Culture-independent studies rely on the quantity and quality of the extracted environmental metagenomic DNA (mDNA). To fully access the plant tissue microbiome, the extracted plant mDNA should allow optimal PCR applications ... -
Microbiome enrichment from contaminated marine sediments unveils novel bacterial strains for petroleum hydrocarbon and heavy metal bioremediation
Dell’Anno, Filippo; Joaquim van Zyl, Leonardo; Trindade, Marla (Elsevier, 2023)Petroleum hydrocarbons and heavy metals are some of the most widespread contaminants affecting marine ecosystems, urgently needing effective and sustainable remediation solutions. Microbial-based bioremediation is gaining ... -
Novel phages of healthy skin metaviromes from South Africa
van Zyl, Leonardo Joaquim; Abrahams, Yoonus; Stander, Emily Amor; Kirby-McCollough, Bronwyn; Jourdain, Roland; Clavaud, Cécile; Breton, Lionel; Trindade, Marla (Nature Publishing Group, 2018)Recent skin metagenomic studies have investigated the harbored viral diversity and its possible influence on healthy skin microbial populations, and tried to establish global patterns of skin-phage evolution. However, ... -
Use of the mcherry fluorescent protein to optimize the expression of class I lanthipeptides in escherichia coli
Van Zyl, Winschau F; Trindade, Marla (BioMed Central Ltd, 2023)Background: Lanthipeptides are a rapidly expanding family of ribosomally synthesized and post-translationally modified natural compounds with diverse biological functions. Lanthipeptide structural and biosynthetic genes ... -
Virome assembly and annotation: A surprise in the Namib Desert
Hesse, Uljana; Van Heusden, Peter; Kirby, Bronwyn; Olonade, Israel; van Zyl, Leonardo Joaquim; Trindade, Marla (Frontiers Research Foundation, 2017)Sequencing, assembly, and annotation of environmental virome samples is challenging. Methodological biases and differences in species abundance result in fragmentary read coverage; sequence reconstruction is further ...
