Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken Jan 2012

Diversity Of The Ohio River Bacterial Communities Using Next-Generation Sequencing Techniques, Emily Michele Anneken

Theses, Dissertations and Capstones

The ability to sequence bacterial genetic material directly from environmental samples has unlocked the field of metagenomics. Next-generation sequencing techniques, such as pyrosequencing, have been instrumental in providing knowledge about bacterial communities. This study focused on identifying the bacterial diversity of the Ohio River via pyrosequencing and compared the diversity of cultivable bacteria versus the entire river community. To ensure the maximum number of cultivable bacteria was obtained, cultures were grown on nonselective media and incubated at river temperature. Bacterial DNA was extracted, sequenced, and classified. The dominant phyla for the Ohio River included Cyanobacteria (38-66% of the total), Actinobacteria ...
