Bioprospecting of Novel Extremozymes From Prokaryotes-The Advent of Culture-Independent Methods.

Extremophiles are remarkable organisms that thrive in the harshest environments on Earth, such as hydrothermal vents, hypersaline lakes and pools, alkaline soda lakes, deserts, cold oceans, and volcanic areas. These organisms have developed several strategies to overcome environmental stress and nutrient limitations. Thus, they are among the best model organisms to study adaptive mechanisms that lead to stress tolerance.

Modeling gut-brain interactions in zebrafish.

Mounting clinical and experimental evidence suggests the gut-brain interplay as a novel important paradigm in translational neuroscience, including the critical role for gut microbiota in modulating brain development and behavior, as well as neuroimmune and neuroendocrine responses. Animal models are an indispensable tool in studying the central nervous system (CNS) disorders and their mechanisms. Recently, the zebrafish (Danio rerio) has become a powerful new model organism in neuroscience, including studying the gut-brain axis.
