Summary: Coir pith, a hazardous coir industrial waste, was subjected to 50 days of vermicomposting with Eudrilus eugeniae using different combinations of nitrogenous legume plant Gliricidia sepium and cattle dung, following 21 days of precomposting with Pleurotus sajor-caju spawn. The vermicompost exhibited increased electrical conductivity, total NPK, and calcium, as well as decreased organic matter, total organic carbon, C/N ratio, C/P ratio, and total phenolic content. The activity of dehydrogenase, urease, and cellulase reached its peak at 30 days of vermicomposting. The stability and maturity of the vermicompost were confirmed through phytotoxicity studies, C/N ratio, and enzyme activities. The 2:3:1 ratio of coir pith, Gliricidia sepium, and cow dung proved to be an effective combination for nutrient-rich vermicompost production (N: 2.43%; P: 0.92%; K: 2.09%). The total phenolic content decreased during vermicomposting, with the lowest final content observed in the 2:3:1 combination (21.26 mg/g GAE compared to the initial level of 105.56 mg/g GAE). The concentration of total phenol contents was inversely related to the germination index of Brassica juncea, indicating its potential role in phytotoxicity. The growth and fecundity of Eudrilus eugeniae in the 2:3:1 combination demonstrated the acceptability and rapid decomposition of coir pith substrate into vermifertilizer.

Summary: This study demonstrates that sewage sludge contaminated with microplastics can be safely remediated through vermicomposting, with minimal effects on earthworms and chemical properties. In fact, the presence of microplastics may even result in a reduction in cadmium content in the vermicompost compared to the control group. The biodegradation of microplastics during vermicomposting also indicates a potential for environmental remediation.

Summary: This study investigated the biotransformation of elephant and cow dung using the earthworm Eudrilus eugeniae. It was found that the treatment with a 1:1 ratio of elephant and cow dung (T3) had the highest NPK content and nutrient recovery efficiency. The vermicompost produced was found to be free of phytotoxicity and supported plant growth effectively after two cycles.

Summary: Among annelids, earthworms are known for their remarkable ability to regenerate lost segments. The study found that the clitellum plays a crucial role in the successful regeneration of earthworms. Histological studies and transcriptomic analysis revealed the importance of the proliferation of the longitudinal cell layer in the clitellum for earthworm regeneration. The data provided insights into the complex process of earthworm regeneration.

Summary: Cigarette butts, made of non-degradable cellulose acetate and containing toxic nicotine, are a major source of pollution in soil and water. This study investigates the effects of cigarette butts and tobacco leaves on an earthworm model organism. The results show that nicotine is highly toxic to earthworms, causing mortality and decreased reproduction rates.

Summary: This study investigated the litter consumption of the African nightcrawler earthworm Eudrilus eugeniae under different tropical conditions using DNA barcoding to identify specimens. The results showed that litter consumption significantly increased in refuse disposal and agricultural soils compared to other soil types, with optimum moisture levels between 24% and 50%. Litter type did not affect consumption rate, but higher population density led to increased litter mass loss. The study suggests that habitat components and population density determine litter consumption rates of E. eugeniae, which have a strong direct effect on the decomposition of plant materials.

Summary: This study examines the toxic effect of chemically engineered silver nanoparticles (SNPs) and polyvinylpyrrolidone-capped silver nanoparticles (PVP-SNPs) on the earthworm Eudrilus eugeniae (E. eugeniae). The lethal concentration (LC50) of SNPs and PVP-SNPs were found to be 22.66 and 43.27 mu g/mL, respectively. SNPs were found to increase the activity of antioxidant enzymes compared to PVP-SNPs. Additionally, the earthworms exhibited a unique behavior called autotomy, where they could amputate their body segments after exposure to SNPs and PVP-SNPs, presumably as a means to escape toxic contaminants and predators.
