LAB 5: Con't. Project: Soil Microbial Communities & Diversity

Identification of your cultured soil bacteria from your pure colonies

Molecular Strategy for Indentification of Culturable & Non-culturable Bacteria in a Soil Sample

Identify Bacteria from Genomic DNA from Isolated Pure Colonies



Choose 8 isolated bacterial colonies per person



Lyse Cells by boiling


PCR amplify 16srDNA with the bacterial primers: 8F and 1492R



Visualize PCR product by agarose getl electrophoresis


Prepare PCR product dor DNA sequencing with ExoSap


Submit PCR products for DNA sequencing



Determine id of cultured and isolated soil organisms with sequence comparisons to database
