Actinomycetes are gram positive, filamentous bacteria that produce useful antibiotics, antitumor agents, and agricultural products. A series of enrichments were undertaken to isolate actinomycetes from local soils, varying enrichment media, antibacterials, and soil treatments (including heat and CaCO3). Isolates were characterized by 16S rDNA sequencing, phenotypic and morphological observations, and antibiotic production. The genetic tractability of select isolates was analyzed using a panel of integrating vectors derived from ɸC31, ɸBT1, and OzzyJ phage using intergeneric conjugation. Further, a semi-degenerate multiplex PCR assay to detect ɸBT1 genomic integrants was designed and tested for the first time. Finally, PCR screens were used …

Volcanic caves have been little studied for their potential as sources of novel microbial species and bioactive compounds with new scaffolds. We present the first study of volcanic cave microbiology from Canada and suggest that this habitat has great potential for the isolation of novel bioactive substances. Sample locations were plot ted on a contour map that was compiled in ArcView 3.2. Over 400 bacterial isolates were obtained from the Helmcken Falls cave in Wells Gray Provincial Park, British Columbia. From our preliminary screen, of 400 isolates tested, 1% showed activity against extended spectrum ß-lactamase E. coli, 1.75% against Escherichia …
