“…Addition of CD with raw materials also results in a signi cant enhancement in ash level in the end products (Table 1). The present nding showed similarity with the previous works of Devi and Khwairakpam (2020) who observed the increasing ash contents in the vermicomposted samples of Lantana camara. The degradation of cellulose, hemicelluloses, lignin; release of CO 2 and mineralization of the waste materials during vermicomposting enhance the ash values in the nal products (Chatterjee et al 2016).…”

Vermicomposting potential of waste biomass of potato crop that are generated at the time of harvesting was studied employing Eisenia fetida. The experiment was carried out in pots taking two treatments; in one only potato plant biomass (PPB) was taken as raw materials whereas in the other a mixture of PPB with cow dung was engaged in the proportion of 5:1. The vermicomposted materials showed a reduction in C/N ratio, humi cation index, enhancement in nutrients pro les, ash contents, nitrogen-xing, phosphate and potassium solubilizing bacterial population. The macronutrient enhancement in the vermicompost samples was recorded 3.8-4.4 fold for total N, 5-5.6 fold in available P, 1.6 fold in total K, 5.2-6.2 fold in total Ca and 1.6 fold in total Mg contents. The reduction in C/N was found in the rage of 92.5-94.4% in the vermicompost samples. The scanning electron microscope (SEM) images showed higher disintegration in the vermicompost products when compared with initial raw material and compost samples. Addition of cow dung signi cantly enhanced the quality and quantity of vermicompost nal products besides positively affecting the earthworm population and biomass by the end of 60 days of experimental trials.

“…The final pH values of both the coprolites from GS and GM were slightly acidic to alkaline attributed to gut microbial activity, indicating that these coprolites could be useful to remediate soil reaction. Vermicomposting of fruit and vegetable wastes 81 , 82 ; seaweeds, sugarcane trash, coir pith amended with cow dung 83 ; and flowering plants ( Lantana camara ) 84 was also reported to produce vermicompost with a pH close to neutral. Analyses of variance for total organic carbon indicated significant ( p < 0.05) differences between the coprolites from GS (18.24%) and GM (27.18%) with their controls GS (control) (29.42%) and GM (control) (32.02%) respectively.…”

Himalayan ecosystem is characterized by its fragile climate with rich repositories of biodiversity. Waste collection and disposal are becoming increasingly difficult due to topographical variations. Aporrectodea caligenosa, a versatile psychrophillic soil dweller, is a useful biocatalyst with potent bio-augmented capability for waste treatment at low temperatures. Microcosm experiments were conducted to elucidate the comprehensive nature of biogenic nitrogen transformation to NH4+ and NO3− produced by coupling of earthworm-microbes. Higher biogenic recovery of NH4+-N from coprolites of garden soil (47.73 ± 1.16%) and Himalayan goat manure (86.32 ± 0.92%) with an increment of 14.12 and 47.21% respectively over their respective control (without earthworms) with a linear decline beyond 4th week of incubation was reported. NO3–-N recovery progressively sustained in garden soil and goat manure coprolites during entire incubation with highest 81.81 ± 0.45 and 87.20 ± 1.08 µg-N g−1dry weight recorded in 6th and 5th week of incubation respectively and peak increments as 38.58 and 53.71% relative to respective control (without earthworms). Declined NH4+–N in coprolites at low temperature (15.0 ± 2.0 °C) evidenced increased nitrification rates by taking over the process by abundant nitrifying microbes. Steady de-nitrification with progressive incubation on an average was 16.95 ± 0.46 ng-N g−1 per week and 21.08 ± 0.87 ng-N g−1 per week compared to 14.03 ± 0.58 ng-N g−1 per week and 4.50 ± 0.31 ng-N g−1 per week in respective control treatments. Simultaneous heterotrophic nitrification and aerobic denitrification (SHNAD) was found to be a prominent bioprocess at low temperature that resulted in high and stable total nitrogen and nitrate accumulation from garden soil and goat manure with relative recovery efficiency of 11.12%, 14.97% and 14.20%; 19.34%. A. caligenosa shows promising prospects for mass applicability in biogenic N removal from manure of Himalayan goat.

Ageratum conyzoides, an herb found throughout the year, is generally considered as a weed: it causes reduction in soil productivity and leads to health hazards for cattle and humans. However, its biomass can easily represent a cost‐effective source, which can be used for lignocellulosic biofuel production. The conversion of lignocellulosic biomass to ethanol has drawn much attention in recent times due to abundance of biomass. In the present study, the cellulose and hemicellulose biomass of the leaf and stem of A. conyzoides was converted to sugars using acid hydrolysis.146.01 ± 02 mg/g of fermentable sugar was obtained from A. conyzoides. The maximum ethanol concentration 11.89 g/L was obtained after 7 days. Scanning electron microscopy was used to characterize the surface morphology after acid hydrolysis of biomass. In the current study, the residues of acid hydrolysis and fermented wastewater was used for biogas production through anaerobic digestion. The yield of biogas from the residues of acid hydrolysis and fermented wastewater was 204 L kg−1VS. The results obtained indicate that A. conyzoides may be considered as a promising feedstock for bioethanol and biogas production.
