H2 rather than acetate stimulated methanogenesis in the methanogenic gut content enrichments, and acetogens appeared to dissimilate supplemental H2 to acetate in methanogenic enrichments. Department of Animal Science. The alimentary canal is a straight from the mouth upto the anus. The objective of this study euddrilus to resolve trophic interactions of bacteria and methanogens in the methanogenic food web in the gut contents of E.

Hydrogenotrophic methanogens affiliated with Methanobacteriaceae and Methanoregulaceae were linked to methanogenesis, and acetogens related to Peptostreptoccocaceae were likewise found to be participants in the methanogenic food web. Views Read Edit View history. Retrieved from ” https: In the study of reproductive system, 2 pairs of eudrilsu in the lobe form are found at the posterior faces of the 10th to 11th segment and 11th to 12thsegment septa, 2 pairs of large seminal vesicles are on 11th and 12th segments wugeniae the prostate euggeniae is in the form of euprostate which looks like finger.

Concomitant fermentations were augmented by the rapid consumption of glucose, yielding numerous products, including molecular hydrogen H2carbon dioxide CO2formate, acetate, ethanol, lactate, succinate and propionate.


Anatomy and life cycle of Eudrilus eugeniae

Lookup the document at: The anoxic saccharide-rich conditions of the earthworm gut provide an ideal transient habitat for ingested microbes capable of anaerobiosis. Eudrilus eugeniae Scientific classification Kingdom: Articles with ‘species’ microformats All stub articles.

Aeromonadaceae-affiliated facultative aerobes, and obligate anaerobes affiliated to Lachnospiraceae, Veillonellaceae and Ruminococcaceae were associated with the diverse fermentations. The growth of individual earthworms increased the lower the population density, but the greatest overall earthworm biomass production occurs at the highest population density.

RNA-based stable isotope probing of bacterial 16S rRNA as well as mcrA and mrtA the alpha subunit of methyl-CoM reductase and its isoenzyme, respectively of methanogens was performed with [ 13 C]-glucose as a model saccharide in the gut contents.

African Zoology

Methanogenesis was ongoing during incubations, and 13 C-labeling of CH4 verified that supplemental [ 13 C]-glucose derived carbon was dissimilated to CH4.

The clitellum is on 14th to 18th segments, a pair of female pores on the 14th segment and a pair of male pores at the joint of the 17th and 18thsegment.

Bangkhen Campus, Bangkok Thailand. Throughout its life cycle, E.

Impact of Parthenium weeds on earthworms (Eudrilus eugeniae) during vermicomposting.

Eudrilus eugeniae Kinberg The segments of the Brandling worm Eisenia fetida alternate reddish-orange and brown; the posterior segments do not taper, and the final segment is blunt. Results of the anatomy study of Eudrilus eugeniae showed that there wudrilus eight setae on each segment, arranging in four pairs of ventrolateral form.

Two ovaries are found on the posterior face of the 12th and 13th segments and 2 pairs of seminal receptacles on the 10th and 11thsegments. From Wikipedia, the free encyclopedia. Anatomy and life cycle of Eudrilus eugeniae.

Four pairs of pseudoheart are found for vascular system. Eudrilus eugeniae is a species of earthworm native to tropical west Africa and now widespread in warm regions, both wild and under vermicompostalso called the African night crawler. The African nightcrawler has a uniform purple-grey sheen and the posterior segments are evenly tapered to a point.

Results of the study of life cycle showed that cocoon to white young worm days, white young worm to red young worm days, and red young worm to clitellum days. This annelid -related article is a stub. Access the full text: Euerilus page was last edited on 28 Septemberat It was recently discovered that the earthworm Eudrilus eugeniae from Brazil can emit methane CH4 and that ingested methanogens might be associated with this emission.
