Extreme environments Microbiome Analysis

Extreme environments represent unique ecosystems that provide a particularly interesting natural context because of the specific challenges to maintain basic life functions under challenging conditions. Bacteria adopt various strategies to acquire multiple systems so as to thrive against harsh environment such as glacial, deserts, hot springs, ocean bottoms, oligothrophic seas, hydrothermal vents, rocks of the earth's mantle. High-throughput DNA sequencing approaches promise to reveal new insights into diverse environmental and host-associated microbial communities. Omics-driven approaches in combination with high-throughput DNA sequencing technology are nowadays considered reliable and cost-effective tool for the study of the functional and mechanistic underpinnings of metaorganism biology in extreme environments.

Extreme Environments Microbiota Analysis

Potential Research Directions of Extreme environments Microbiota Analysis

• Explore the roles of extremophiles in ecosystems, including climate regulation.
• Explore the way extremophiles preserve their biological functions
• Explore the usefulness of "extremozymes" for biotechnologies
• Explore the extremophilic organisms and the limits of life

Technical Platforms

With our next-generation sequencing (NGS) technology, PacBio SMRT sequencing, and Nanopore sequencing platforms, we have the tool to identify, quantify and analysis the extreme environments microbiota. With this high-throughput technology we can perform complete metagenomics studies capable of surveying the genomes of entire communities, including those of unculturable organisms.
