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 ... -
Isolation and characterization of strain exiguobacterium sp. Krl4, a producer of bioactive secondary metabolites from a Tibetan glacier
Tedesco, Pietro; Esposito, Fortunato Palma; van Zyl, Leonardo Joaquim (MPDI, 2021)Extremophilic microorganisms represent a unique source of novel natural products. Among them, cold adapted bacteria and particularly alpine microorganisms are still underexplored. Here, we describe the isolation and ... -
Three novel bacteria associated with two centric diatom species from the Mediterranean Sea, Thalassiosira rotula and Skeletonema marinoi
Di Costanzo, Federica; Di Dato, Valeria; van Zyl, Leonardo Joaquim (MPDI, 2021)Diatoms are a successful group of microalgae at the base of the marine food web. For hundreds of millions of years, they have shared common habitats with bacteria, which favored the onset of interactions at different ...
