The traditional view of cellulose digestion in animals is that they cannot produce their own cellulase, and so rely on gut microorganisms to hydrolyse cellulose. A classic example of this symbiosis is that between phylogenetically lower termites and the unicellular organisms (protists) that colonize their hindguts: cellulose fermented to acetate by the protists can be used as an energy source by the termite. There is evidence for the production of endogenous cellulase components by termites and… 
Animal cellulases
TLDR
The presence and nature of endogenous cellulases in higher animals are described and the nature of cellulase genes reported from arthropods and nematodes are discussed.
Animal cellulases with a focus on aquatic invertebrates
Cellulose is utilized as a nutritional source by various organisms. For a long time it was believed that only protozoa, bacteria, and fungi, in addition to plants and photosynthetic bacteria, are
Correlation of cellulase gene expression and cellulolytic activity throughout the gut of the termite Reticulitermes flavipes.
TLDR
The results suggest the presence of a single unified cellulose digestion system, whereby endogenous and symbiotic cellulases work sequentially and collaboratively across the entire digestive tract of R. flavipes.
Symbiotic adaptation of bacteria in the gut of Reticulitermes speratus: low endo-beta-1,4-glucanase activity.
The termite is a good model of symbiosis between microbes and hosts and possesses an effective cellulose digestive system. Oxygen-tolerant bacteria, such as Dyella sp., Chryseobacterium sp., and
Cellulases of Animal Origin
TLDR
It is supposed that a GHF 9 cellulase gene originated in an ancestral species among arthropods and was carried to the present species during the course of phylogenetic development.
Cellulolytic systems in insects.
TLDR
DNA sequences of cellulase and associated genes, as well as physiological and morphological information about the digestive systems of cellulases-producing insects, may allow the efficient use of cellulosic biomass as a sustainable energy source.
The cellulolytic system of the termite gut
TLDR
The understanding of the principles of cellulose degradation in this natural polymer-degrading ecosystem could be helpful for the improvement of the biotechnological hydrolysis and conversion of cellulOSE, e.g., in the case of biogas production from natural renewable plant material inBiogas plants.
Evidence for the presence of a cellulase gene in the last common ancestor of bilaterian animals
TLDR
The results suggest that at least one family of endogenous cellulases may be more widespread in animals than previously thought and questions the idea of lateral gene transfer into the ancestors of the latter.
Gut Microbiota from Lower Groups of Animals: An Upcoming Source for Cellulolytic Enzymes with Industrial Potentials

TLDR
In this review, thorough literature studies have been made to explore the invertebrate groups that are novel sources of cellulolytic gut bacteria with high efficacy for enzyme production.
Structure and function of a cellulase gene in redclaw crayfish, Cherax quadricarinatus.
TLDR
The genomic organisation of an endogenous GHF 9 gene in redclaw crayfish reveals the conservation of both intron position/phase and splice sequence, which adds support to an argument for an ancestral animal cellulase gene.
