1 Introduction The digestive tract of herbivorous animals is considered an ideal location for searching for enzymes capable of degrading cellulose and lignin [1]. In this context, research has identified the presence of the DUF152 laccase family member RL5 in the bovine rumen, exhibiting sequence characteristics distinct from known laccases [2]. For herbivorous animals such as turtles, the ability to degrade lignin to some extent within their intestinal tract is indispensable.
