De novo transcriptome assembly, functional annotation and differential gene expression analysis of juvenile and adult E. fetida, a model oligochaete used in ecotoxicological studies Biol. Res.
Thunders,Michelle; Cavanagh,Jo; Li,Yinsheng.
Abstract Background Earthworms are sensitive to toxic chemicals present in the soil and so are useful indicator organisms for soil health. Eisenia fetida are commonly used in ecotoxicological studies; therefore the assembly of a baseline transcriptome is important for subsequent analyses exploring the impact of toxin exposure on genome wide gene expression. Results This paper reports on the de novo transcriptome assembly of E. fetida using Trinity, a freely available software tool. Trinotate was used to carry out functional annotation of the Trinity generated transcriptome file and the transdecoder generated peptide sequence file along with BLASTX, BLASTP and HMMER searches and were loaded into a Sqlite3 database. To identify differentially expressed...

Diversidad bacteriana en el tracto digestivo de la lombriz de tierra Pontoscolex corethrurus. Colegio de Postgraduados
Brito Vega, Hortensia.
El objetivo del presente trabajo fue estudiar la diversidad bacteriana en el contenido digestivo de la lombriz de tierra endogea Pontoscolex corethrurus. El muestreo de la especie P. corethrurus se realizó en dos localidades de Veracruz, México: Plan de las Hayas, zona ganadera con suelo arcilloso y La Mancha, zona de reserva ecológica y con suelo arenoso. El intestino de las lombrices fue dividido en cuatro secciones (A, B, C y D). Bajo condiciones asépticas, se prepararon diluciones decimales con el contenido intestinal empleando el medio líquido Brain Heart Infusion. Posteriormente, la suspensión del contenido intestinal se sembró en medios específicos. La identificación taxonómica de los aislamientos bacterianos puros se realizó por dos...

Earthworm and maggots meals as potential fishmeal replacement OceanDocs
Yaqub, H.B..
Three meals were formulated from the earthworm (Endrilus eugineae) and maggot (Musca domestica) and fish (Engraulis encrosicolus). These meals were evaluated as a potential replacement for fishmeal. This is because fishmeal could be very expensive at times. The three meals were used in feeding the catfish (Heterobranchus isopterus) fry for 30 days. The study was conducted in 1991 at the Institute of Renewable Natural Resources Farm, University of Science and Technology. Two replicates were done using four hapas in each replicate. Each hapa was stocked with 50 fry and fed. Those in the fourth hapa were not fed to ascertain the effect of supplementary feeding on the growth of the fish. Weight increment was found to be less in the fourth hapa than the...

Evaluación y caracterización de sustratos orgánicos para el crecimiento de plántulas de caña de azúcar. Colegio de Postgraduados
Domínguez Gamas, Miriam Isela.
La investigación de nuevos materiales para la formulación de mezclas que sirvan como sustrato o medio de crecimiento vegetal se ha constituido en una actividad fundamental. El objetivo de este trabajo fue evaluar la capacidad de diferentes tipos de vermicompostas, a fin de establecer su viabilidad como parte de un sustrato, para la siembra de dos variedades de caña de azúcar (CP-722086 y MEX-69290), a nivel de plántula. Se evaluaron, diferentes mezclas de residuos agroindustriales cachaza, bagazo, estiércol de ganado, cascarilla de cacao y biochard, los cuales fueron sometidos a vermicompostaje por 118 días. Al término del proceso se realizaron análisis químicos de las lombricompostas obtenidas, para su caracterización físico-química, en base a la norma...

Initial development of lettuce in vermicompost at higher trichoderma doses Horticultura Brasileira
Wiethan,Maria MS; Bortolin,Gabriel S; Pinto,Renata S; Silva,Antonio Carlos F.
ABSTRACT The study aimed to evaluate the initial development, as well as, the chemical characteristics of lettuce plants grown in substrate with high concentrations of bioagent (trichoderma). A completely randomized design with four replicates was used. The treatments, applied to a substrate composed of a blend of vermicompost and commercial substrate, were established by the following doses of the commercial product ICB Nutrissolo Trichoderma: T1) 0.0; T2) 1.0; T3) 2.0; T4) 4.0; T5) 8.0 and T6) 16.0x1011 conidia kg-1 of product. After inoculation, the substrate was placed in trays, where 50 lettuce seeds were sown on each replication. Plants were thinned after emergency stabilization, maintaining ten seedlings per tray. At 28 days after sowing, the...

Interactions of juvenile Lumbricus terrestris with adults and their burrow systems in a two-dimensional microcosm PAB
Grigoropoulou,Niki; Butt,Kevin R.; Lowe,Christopher N..
The objective of this work was to evaluate interactions of Lumbricus terrestris juveniles with adults and with inherited burrow systems. An experiment was set up using a two dimensional Evans' boxes microcosm. Adult L. terrestris were added to 16 boxes (one individual per box) and kept in darkness at 17ºC along with eight unoccupied boxes for two months. The adult L. terrestris were removed from eight randomly selected boxes, and L. terrestris juveniles were added (one juvenile per box), composing three treatments with eight replicates: 1, with an adult in an inherited burrow (ABJ); 2, alone in an inherited burrow (BJ); and 3, alone in a previously uninhabited box (J). The proportion of juveniles occupying adult burrows observed was significantly different...

Microflora dynamics in earthworms casts in an artificial soil (biosynthesol) containing lactic acid oligomers BABT
Alauzet,Nathalie; Roussos,Sevastianos; Garreau,Henri; Vert,Michel.
Studies were performed to appreciate the presence of micro-organisms able to degrade OLA, in earthworms casts or in the surroundings. Worms were grown in biosynthesol, an artificial soil. The counting of bacteria and fungi in earthworms casts and in biosynthesol without earthworms suggested that earthworms ate some of the micro-organisms. The main filamentous fungi genera found were Aspergillus, Trichoderma, Fusarium and Penicillium. Previous results in the literature have shown that some species from the Aspergillus and Fusarium genera were able to degrade OLA and other aliphatic esters. It could be suggested that these two genera and some bacteria were responsible for the pre-degradation of OLA, and that earthworms might eat them.

PREDICTION OF BIOAVAILABILITY OF CHLORPYRIFOS RESIDUES IN SOIL TO EARTHWORMS J. Soil Sci. Plant Nutr.
Wu,X.M; Yu,Y.L; Li,M; Long,Y.H; Fang,H; Li,S.N.
An incubation test was conducted to investigate the effect of aging on bioavailability of chlorpyrifos in soil and to assess the feasibility of chemical extraction techniques for predicting bioavailability of chlorpyrifos in soil. Chlorpyrifos was spiked into sterilized soil and aged in microcosms for up to 120 days. The earthworms were incubated in the spiked soils, at 0, 7, 14, 30, 60, and 120 days after spiking, for a period of 7 days. After exposure, chlorpyrifos concentrations in the earthworm tissues were determined. Change in chemical extractability of soil-chlorpyrifos was measured using a several solvent systems including methanol, methanol-water (9:1), acetone-water (5:3), and water. The results show that chemical extractability and earthworm...
