Comparative assessment of the aerobic and anaerobic microfloras of earthworm guts and forest soils.

Abstract

Aerobic and anaerobic microbial potentials of guts from earthworms (Lumbricus rubellus Hoffmeister and Octolasium lacteum (Oerl.)) collected from a beech forest were evaluated. On the basis of enumeration studies, microbes capable of growth under both aerobic and anaerobic conditions were more numerous in the earthworm intestine than in the beech forest soil from which the worms were obtained. The intestine of worms displayed nearly equivalent aerobic and anaerobic microbial growth potentials; in comparison, soils displayed greater aerobic than anaerobic microbial growth potentials. Hence, the ratio of microbes capable of growth under obligately anaerobic conditions to those capable of growth under aerobic conditions was higher with the worm intestine than with the soil. Process level studies corroborated these population differentials: (i) under anaerobic conditions, worm gut homogenates consumed glucose, cellobiose, or ferulate more readily than did soil homogenates; and (ii) under aerobic conditions, worm gut homogenates consumed cellobiose or oxygen more readily than did soil homogenates. Collectively, these results reinforce the general concept that the earthworm gut is not microbiologically equivalent to soil and also sug...Continue Reading

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
