Isolation and Characterisation of Microbial DNA from Rain Tree Barks by Mun, Chee Onn

“…The presence of archaea cannot be indicated due to unspecific amplification and no single band with the expected size was obtained. No difference between non-orchid and orchid-colonised bark samples in terms of amplified rDNA in the range of 8.2 to 14.1 ug, which were sufficient for next generation sequencing (NGS) for rain tree bark metagenomics study, specifically on the ecology of microorganisms on rain tree bark.…”
