Extremophilic microorganisms such as those that thrive in high-salt and high-alkaline environments are promising candidates for the recovery of useful biomaterials including polyhydroxyalkanoates (PHAs). PHAs ideal alternatives to synthetic plastics because they biodegradable, biocompatible, environmentally friendly. This work was aimed at conducting a bioprospection bacteria isolated from hype...

Mesoceration Janssens, 1967 is the most speciose genus of Prosthetopinae, most of the 44 described species being restricted to South Africa, and almost all occupying the benthic zone of streams and rivers. Here seven species are described as new: Mesoceration caniplenum sp. nov., M. foggoi sp. nov., M. helmei sp. nov., M. hirsutum sp. nov., M. rugulosum sp. nov., M. sewefonteinense sp. nov. and...

A short-timescale sampling of phytoplankton abundance and diversity was carried out at Redang Island waters, South China Sea. Physico-chemical variables measured at four intervals over a day were relatively stable (temperature = 29 ± 0.6°C ; salinity = 27 ± 2 ppt, pH = 7.8 ± 0.1; total alkalinity = 2025 ± 33 μeq l–1) whereas inorganic nutrient concentrations (NH4 = 1.36 ± 0.51 μM; NO2 = 0.06 ± ...
