“…Our research was in line with previous report according to the research of Hui et al (2007) [21]. Majlessi et al (2012) reported that vermicomposting process due to the depletion of easily degradable carbon compounds and C losses as CO 2 [22], Lores et al (2006) stated that the vermicomposting process involved the activity of earthworms which modify wastes physically and feces excreted by worms can increase the activity of the microorganisms so that the rate of mineralization to be faster [23]. 132 measuring compost maturity [22].…”

Chemical composition of compost is an important indicator that determines the quality of compost. This study compared the chemical composition of vermicompost resulting from the process of vermicomposting alone with combined vermicomposting and composting with addition of egg shells flour and fish meal. Organic wastes used were the mixture of spent mushrooms waste, coconut husks, cow dung, vegetables residue, and leaf litter. Lumbricus rubellus was the species of earthworm used in the vermicomposting process. In the composting process, egg shells flour and fish meal are added into the vermicompost as additives materials. The results indicate that the combined vermicomposting and composting process with addition the additives materials improves the chemical composition of vermicompost compared to using vermicomposting process alone. The change of chemical composition was indicated by a decrease in C-organic content and C/N ratio by 29% and 99%, respectively, while the content of N, P, K and S increased by 52%, 67.5%, 29% and 25%, respectively due to the addition of additives material in the composting process. The largest increase of vermicompost nutrient content occurred in the Ca content by an average of up to 7-fold. While polyphenols, lignin and cellulose content of vermicompost decreased slightly. The treatment of two mixture (a) spent mushrooms waste, cow dung and vegetables residue, and (b) spent mushroom waste, cow dung, vegetables residue, and leaf litter gave the best chemical composition. However, to determine the quality, we need to test the product in a plant growth bioassay as a follow-up study.

“…A higher fungal biomass was found at intermediate and high densities of earthworms (50 and 100 earthworms per mesocosm, respectively), which suggests that there may be a threshold density of earthworms at which fungal growth is triggered. This priming effect on fungal populations was also observed in previous short-term experiments in the presence of the epigeic earthworms Eudrilus eugeniae and Lumbricus rubellus fed with pig and horse manure, respectively [16,86]. These contrasting short-term effects on bacterial and fungal populations are thus expected to have important implications on decomposition pathways during vermicomposting because important differences exist between both microbial decomposers related to resources requirements and exploitation [92].…”

“…During these processes the effects of earthworms are mainly indirect and derived from the GAPs [17]. Overall, vermicomposting includes two different phases regarding earthworm activity: (i) an active phase during which earthworms process the organic substrate, thereby modifying its physical state and microbial composition [86], and (ii) a maturation phase marked by the displacement of the earthworms towards fresher layers of undigested substrate, during which the microorganisms take over the decomposition of the earthworm-processed substrate [17][18]. The length of the maturation phase is not fixed, and depends on the efficiency with which the active phase of the process takes place, which in turn is determined by the species and density of earthworms, and the rate at which the residue is applied [8].…”

“…Previous comparisons between vermicompost and compost with respect to microbial communities [103][104][105] are difficult to interpret because different feedstocks were used for each process. Compost feedstocks are known to alter the material's effects on the structure of the microbial communities [86], so it is essential to use composts made from the same feedstock in order to draw valid comparisons between the two biological processes. Furthermo r e , i t m a y b e e x p e c t e d t h a t d i f f e r e n t h y b r i d s o r p l a n t genotypes will respond differently to vermicompost, considering that plant genotype determines important differences in nutrient uptake capacity, nutrient use efficiency and resource allocation within the plant.…”

“…Las lombrices participan en el proceso realizando diferentes acciones a diferentes niveles espaciales y temporales; entre sus roles más importantes cabe destacar: a) la fragmentación física del sustrato orgánico que aumenta la superficie de ataque para los microorganismos al fragmentarlo; b) la modificación, transporte e inóculo de la microflora presente en el residuo (Lores et al 2006, Aira et al 2007); y c) la aireación del sustrato a través de sus actividades de excavación y deyección. De hecho, las transformaciones de las propiedades físico-químicas y bioquímicas de los sustratos orgánicos (Domínguez 2004) y la rapidez con que estas transformaciones ocurren (Aira et al 2002) hacen del proceso de vermicompostaje un buen sistema para estudiar las relaciones entre las lombrices de tierra epigeas y los microorganismos (Aira et al 2006.…”

Los efectos de las lombrices sobre los microorganismos son directos (incremento o descenso de sus poblaciones al digerir el sustrato) e indirectos (efectos derivados de los directos, como la aparición de las deyecciones en el sustrato fresco). Para delimitar y poder estudiar estos efectos por separado realizamos tres experimentos. En el primero estudiamos el proceso de vermicompostaje con Eisenia fetida de purín de cerdo en todas sus etapas, desde el residuo fresco hasta obtener el vermicompost. En el segundo inoculamos vermicompost en purín de cerdo fresco para estudiar los efectos indirectos de las lombrices de tierra en la degradación del purín. En el tercero analizamos las deyecciones frescas para estudiar los efectos directos de las lombrices de tierra en los microorganismos. Las lombrices de tierra dividieron el proceso de vermicompostaje en dos etapas, una inicial, asociada a su presencia en el residuo, caracterizada por el aumento de la biomasa y actividad de los microorganismos; y la etapa final, asociada a la ausencia de las lombrices de tierra, caracterizada por la disminución de la biomasa y actividad microbiana. El inóculo de vermicompost en purín de cerdo produjo el mismo efecto (aumento inicial y posterior descenso) aunque de menor entidad, probando la existencia de efectos indirectos de las lombrices de tierra en el vermicompostaje. En las deyecciones de las lombrices aumentó la biomasa microbiana y la actividad disminuyó, lo que sugiere la existencia de factores implicados en las relaciones lombrices-microorganismos más allá de la simple digestión y los procesos asociados a la inoculación de las deyecciones en el sustrato.

Earthworms and microorganisms: disentangling the black box of vermicomposting. Acta Zoológica Mexicana (n.s.), Número Especial 2: 385-395. ABSTRACT. Earthworms affect microorganisms both directly (enhancing or reducing their populations by digesting the substrate) and indirectly (derived effects, such as the production of castings in the fresh substrate). To separate these effects we performed three experiments. In the first, we studied the whole process of vermicomposting, using Eisenia fetida and pig manure in all stage, from fresh residue to vermicompost. In the second experiment, we inoculated pig manure with vermicompost to study the indirect effects of earthworms on decomposition. In the third, we analysed the fresh casts to study direct
