DNA Extraction

DNA extraction from Ms. trichosporium OB3b is less efficient than DNA extraction from many Type I or Type II methanotrophic bacteria. Existing methods use the neutral lysis/CsCl method or a DNeasy Blood Tissue Kit (Qiagen) for DNA extractions from liquid cultures (Gu et al., 2016; Smith & Murrell, 2011).However, growing liquid cultures to genotype multiple colonies is time-consuming.
