Abstract
The metagenomics approach is an efficient method for obtaining novel biocatalysts and useful genes from uncultured microorganisms within diverse environments. In this study, we constructed a metagenomic library using a South African deep mine biofilm sample. The library was screened for lipolytic activity using LB Tributyrin (TLB). Although we were able to identify 3 diverse esterase enzymes, we found that 70% of the obtained sequence data revealed the presence of enzymes and genes completely unrelated to that of lipolytic enzymes thereby highlighting the limitation of screening with TLB.
Key words: False positives, tributyrin, lipolytic activity, metagenome.
