Initial thermostability assay of xylanase-positive metagenomic library clones. Whole cell lysates of the positive metagenomic clones were incubated in a water bath at 60 °C for 3 days. Samples were taken at regular intervals and residual xylanase activity quantified using the EnzCheck xylanase assay
