Abstract
|
|
|
Extracellular enzymes produced by microbes in hypersaline environments have been reported to possess a wide range of
biocatalytic activities capable of functioning under the prevailing extreme conditions. To facilitate the industrial application of microbial enzymes sourced from extreme environments, we investigated the physiochemical properties and extracellular enzyme activities in solar saltern sediments. Our results indicate that high salinity induces an increase in the levels of dissolved organic carbon (DOC), which enhances the activities of cellulase, chitinase, and sulfatase by increasing the energy supplied to microbes. Therefore, enzymes and microbes that can be potentially used in future industrial applications was found in solar saltern.
