Quizplus · Accepted Answer

Cellulase is primarily produced by bacteria that live in the rumen, which is a specialized stomach compartment found in ruminant animals such as cows and sheep. These bacteria are able to break down cellulose and extract nutrients from plant material, which is a key part of the digestive process for these animals. While other organisms such as fungi and some insects are also capable of producing cellulase, bacteria are the primary source in the rumen.
