Many of the Members on the MMRG have been involved in microbiome analysis for over 20 years and have a strong appreciation for the field. They are dedicated and understand the needs of this new and exciting field that continues to grow at an exponential rate.
If you would like to be part of the MMRG, please contact Scott Tighe at firstname.lastname@example.org. Requirements of the research group are 1) Active membership in the ABRF, 2) copy of your CV, and 3) a letter of interest describing your interest, motivation, and how you can contribute.
The ABRF Metagenomics and Microbiome Research Group is composed of Core lab managers, bench scientists, and bioinformaticists. The goals of the MMRG will be to establish and evaluate techniques that core laboratory operators, directors, managers, and users commonly ask. Initial studies include assembling microbial standards and to characterize shortcomings of current metagenomic techniques. this includes optimizing DNA extraction protocols, library synthesis methods for different NGS platforms and developing best approaches for bioinformatics. The development of bacterial cocktails includes working with specific vendors in the field to establish a bacterial counting platform (similar to simple low cost mammalian cell counters) that can be used for low cost, high speed bacterial cell counting as needed for both research and clinical metagenomic quality control requirements. This enumeration device will be validated against standard techniques such as flow cytometry, Microscopic, and LSC techniques. Development of a fixation technique that preserves DNA and RNA without cell leakage is also required. We intend to work very closely with the appropriate vendor of the field to help advance this technology.

Studies - Ongoing 2019 - 2020: Evaluation of rapid DNA library preparation kit for shotgun metagenomics studies.
The study aims to evaluate and benchmark the performance of rapid DNA library kits for shotgun metagenomics. The general criteria for kits to be evaluated in this study will be based on - variable range of input DNA, enzymatic or transposase-based fragmentation method, one bead clean-up. We will also prep libraries using TE or MQ water to establish baseline data for negative controls and the “kitome”. With this study the MGRG aims to provide a platform to compare the kits for - efficiency, reproducibility, total time, quality, sequencing outcomes, using known DNA known standards, which will be beneficial to the research community.
