| Abstract The utilisation of lignocellulosic material in agricultural processes can be enhanced by appropriate treatment with plant cell wall degrading enzymes Rumen bacteria are a source of plant cell wall degrading enzymes that could prove particularly valuable for improving the digestibility of plant material by farm animals. Cloned genes potentially allow the production of specific enzymes with desirable properties economically and in large quantities, while also providing important basic information on the degradative enzyme systems of these. bacteria. Many genes coding for xylan-degrading activities have now been isolated from rumen bacteria in the host laboratory, including putative xylan debranching activities. This proposal aims first to establish the role and potential for application of an acetyl esterase gene from the rumen anaerobe Ruminococcus flavefaciens while also screening for genes for further debranching activities. Secondly we propose to investigate the structure, regulation and strain distribution of an unique gene cluster concerned with xylan degradation and utilization in R. flavefaciens.
