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. Views Read Edit View history. Throughout its life cycle, E.

Wudrilus and life cycle of Eudrilus eugeniae. The growth of individual earthworms increased the lower the population density, but the greatest overall earthworm biomass production occurs at the highest population density.

From Wikipedia, the free encyclopedia. These findings provide insight on the processes and associated taxa potentially linked to methanogenesis and the turnover of organic carbon in the alimentary canal of methane-emitting E.

Results of the anatomy study of Eudrilus eugeniae showed that there are eight setae on each segment, arranging in four pairs of ventrolateral form. Methanogenesis was ongoing during incubations, and 13 C-labeling of CH4 verified that supplemental [ 13 C]-glucose derived carbon was dissimilated to CH4. The objective of this study was to resolve trophic interactions of bacteria and methanogens in the methanogenic food web in the gut ejgeniae of E. Department of Animal Science. eucrilus


Eudrilus eugeniae – Wikipedia

This page was last edited on 28 Septemberat 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. Concomitant fermentations were augmented by the rapid consumption of glucose, yielding numerous products, including molecular euudrilus H2carbon dioxide CO2formate, acetate, ethanol, lactate, succinate and propionate.

This annelid -related article is a stub. The African nightcrawler has a uniform purple-grey sheen and the posterior segments are evenly tapered to a point. You can help Wikipedia by expanding it.

Anatomy and life cycle of Eudrilus eugeniae

The anoxic saccharide-rich conditions of the earthworm gut provide an ideal transient habitat for ingested microbes capable of anaerobiosis. Aeromonadaceae-affiliated facultative aerobes, and obligate anaerobes affiliated to Lachnospiraceae, Veillonellaceae and Ruminococcaceae were associated with the eudriluz fermentations.

Four pairs of pseudoheart are found for vascular system. Eudrilus eugeniae Kinberg The alimentary canal is a straight from the mouth upto the anus.

Articles with ‘species’ microformats All stub articles. H2 rather than acetate stimulated methanogenesis in the methanogenic gut content enrichments, and acetogens appeared to dissimilate supplemental H2 to acetate in methanogenic enrichments. Eudrilus eugeniae Scientific classification Kingdom: It was recently discovered that the earthworm Eudrilus eugeniae from Brazil can emit methane CH4 and eudrils ingested methanogens might be associated with this emission.


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 eugenie 13 C]-glucose as a model saccharide in the gut contents.

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. Access the full text: Two ovaries are found eudrolus the posterior face of the 12th and 13th segments and 2 pairs of seminal receptacles on the 10th and 11thsegments.

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. Bangkhen Campus, Bangkok Thailand. In the study of reproductive system, 2 pairs of testicles 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 and the prostate gland is in the form of euprostate which looks like finger.

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.
