THESIS ABSTRACT
The microbial diversity that the Ocean offers is tremendous for potential industrial application of biocatalysts. The harsh and broad environment that marine microorganisms face has contributed to the evolution of microbial enzymes that ensure their survival. Microbial enzymes are used in a variety of industries contributing for sustainable processes, but high performance and promiscuous enzymes are still needed. To access new marine microbial enzymes, it is critical the cultivation of bacteria in the laboratory. Current techniques are thought to enable the growth of only ca. 1% of bacteria present in the marine samples. Therefore, it is urgent to develop new cultivation techniques to mimic the natural conditions. This proposal aims to develop novel integrative bioprocesses by accessing the enzymatic machinery of marine bacteria and improving cultivation techniques of ‘unculturable’ bacteria. This will contribute to sustainable industrial applications of marine enzymes with benefits for public health and the environment.
