  abstract = {{T}his study compares the origin and activities of glycolytic enzymes present in the gut contents of some geophagous adult earthworms and demonstrates that all the species did not develop mutualistic relationships with the ingested microorganisms to digest soil organic matter. {A}lthough the glycolytic activities were rather weak in the earthworms studied, they possess quite a complete enzymatic system that allows to degrade root and fungal substrates available in soils. #{M}illsonia anomala$ {O}mo. from {L}amto ({C}{\^o}te d'{I}voire) and #{H}ormogaster elisae$ {A}lvarez from {E}l {M}olar ({M}adrid) developed a strong mutualistic earthworm-microflora digestion system for hydrolysing cellulose : cellulase produced by inested microflora is able to degrade cellulose to cellobiose, cellobiase released by the worm itself breaks down cellobiose into {D}-glucose. {B}oth enzymes found in intestinal contents of #{P}ontoscolex corethrurus$ {M}üll. from {P}alma {S}ola, {V}eracruz ({M}exico) were produced by ingested soil microflora since they were not found in gut tissue culture. {O}n the contrary, #{P}olypheretima elongata$ {P}err. from {S}ainte {A}nne ({M}artinique), #{H}yperiodrilus africanus$ {B}edd. and #{D}ichogaster terrae nigrae$ {O}mo. et {V}ld. from {L}amto ({C}{\^i}te d'{I}voire) possess a complete enzymatic system for hydrolyzing cellulose. {T}hey could synthesize cellulolytic enzymes, i.e. cellulase and cellobiase by themselves. {I}n the course of their digestion, geophagous earthworms seem to display variable adaptive characters which are undoubtedly linked to the different ecological categories and niches.
