Marine microorganisms have long been acknowledged as a significant reservoir of enzymes required for industrial use. In this study, novel extracellular protease Hsl HlyB derived from marine-originated haloarchaeon Halostella pelagica DL-M4 T was identified. contained polycystic kidney disease (PKD) domain and pre-peptidase C-terminal (PPC) at the C-terminus. Truncation replacement extension (CT...

Large regions of Earth's surface are underlain by salt deposits that evaporated from ancient oceans and populated extreme halophilic microbes. Some these halophiles may have been preserved over geological timescales within hypersaline fluid inclusions, but ingresses water and/or anthropogenic activities can lead to the formation alternative habitats, including NaCl stalactites or other speleoth...

The haloarchaeal diversity of four hypersaline alkaline lakes from the Wadi El-Natrun depression (Northern Egypt) was investigated using culture-independent polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) 16S rRNA gene phylotypes, which combined with remote sensing and geographic information system (GIS) data to highlight distribution pattern microbial in water sedi...

BACKGROUND Gas vesicles are hollow, buoyant organelles bounded by a thin and extremely stable protein membrane. They are coded by a cluster of gvp genes in the halophilic archaeon, Halobacterium sp. NRC-1. Using an expression vector containing the entire gvp gene cluster, gas vesicle nanoparticles (GVNPs) have been successfully bioengineered for antigen display by constructing gene fusions betw...
