“…Generally, during the degradation of organic matter, carbohydrates are classified into two groups and used: (i) bacterial components for 30-40%, and (ii) microbial breakdown and evaporation in the form of CO 2 for 60-70% (Hellmann et al 1997). Thus, the amount of carbon shows a declining trend (Zhou et al 2016). However, our results are the opposite of what would be expected over time.…”

This study investigated the effects of three insect larvae on decomposition abilities and survival rates in Experiment 1 or on pH, total nitrogen, total carbon, and C/N ratio in Experiment 2. A total of hatched 7,500 Tenebrio molitor (TM) larvae, hatched 501 Protaetia brevitarsis seulensis (PBS) larvae, and hatched 15,000 Ptecticus tenebrifer (PT) larvae were randomly subjected to three treatments with three replicates. The treatments were as follows: (1) TM, 5,000 g pig manure + 250 g TM larvae; (2) PBS, 5,000 g pig manure + 250 g PBS larvae; and (3) PT, 5,000 g pig manure + 250 g PT larvae. In Experiment 1, there were significant differences (p < 0.05) in the decomposition abilities of the pig manure from the three insect larvae‐treated groups for 15–30 days. No significant differences in survival rates were observed for any of the in all treatments over time. Decomposition ability and survival rates in pig manure were higher in the PT larvae group than in the PBS and PT larvae groups. In Experiment 2, three insect larvae‐treated pig manure treatments had an effect on total nitrogen for 20 and 30 days, total carbon for 10 and 30 days, and C/N ratio for 20 and 30 days. Thus, our results suggest that the three insect larvae have the ability to decompose pig manure to increase for increasing survival rates or might represent a valuable alternative as organic fertilizer, which could increase the total nitrogen content and decrease C/N ratio.

“…Each treatment combination consisted of approximately 2100 kg pig manure, 500 kg fungus residues, and 600 kg rice bran. A previous study had concluded that this is the optimal mixing ratio that is suitable for efficient and quality composting (Zhou et al, 2016). Windrows were not duplicated because of the limitation of both the heavy work and a project budget and because the variability between the respective windrows was similar to that of duplicate samples of a single windrow (Tirado and Michel, 2010).…”

“…However, there are large previous studies of successful pig manure composting mainly using sawdusts, rice brans, and cornstalks as carbon source to mix with pig manure, and rare literature reportes of the co-composting with pig manure and fungus residue, except estimated ratios of pig manure to fungi residue in composting with pig manure and fungus residue (Zhou et al, 2016). In recent years, co-composting has been used commonly in China.…”

Composting of agricultural wastes not only can reduce environmental pollution caused by improper disposal, but recycling of agricultural wastes transforms them into highly valuable products, such as fertilizers or soil conditioners, for agricultural applications. However, the composting process and final product are easily affected by the limited oxygen supply that results from insufficient aeration, especially in the center of a large-scale windrow. Hence, a pilot-scale experiment was conducted to investigate the effects of the turning frequency on the composting efficiency and compost quality of used pig manure and fungus residue, so as to capture an operational technique suitable for the effective co-composting pig manure and edible fungi residue for a large-scale composting plant.

“…Heterotrophic fungi belonging to the genera Aspergillus, Penicillium, Mucor, Rhizopus, Alternaria, Beauveria, Paeclomyces, and Candida have been found to be dung-loving and to tolerate oilcontaminated environments (Dawodi et al 2015;Ughamba et al 2019). Findings from this work corroborate the report of several workers who found Candida sp., C. tropicalis, Rhizopus sp., Mucor sp., Aspergillus spp., A. niger to be strongly associated with cow and pig dung (Obire et al 2008;Zhou et al 2016;Samuel et al 2017) A wide variety of members of fungal divisions are found on dung; the Mucoromyceta (Zygomyceta) usually appear first, followed by Ascomycota and then the Basidiomycota. Presentations in Table 1 indicated that three fungal divisions colonized the test dung specimens; these were saprobes of the division Ascomycota, Mucoromyceta and Basidiomycota.…”

“…Dung is rich in carbohydrates, protein, some water-soluble vitamins and mineral ions (Gupta et al 2016). Being rich in carbon, nitrogen and moisture, pig dung is a good substrate that supports the growth of bacteria and various fungi, that participate in nutrient recycling in the ecosystem (Abdullah 1982;Bills et al 2013;Zhou et al 2016;Samuel et al 2017).…”

Abstract. Enyiukwu DN, Bassey IN, Nwaogu GA, Asamudo NU, Chukwu LA, Monday EA, Maranzu JO. 2021. Pig (Sus scrofa domesticus) dung and their associated fungi: Potential candidates for bio-remediation and nutrients improvement of crude oil contaminated soils. Biodiversitas 22: 3276-3286. Pig dung a common agro-waste material in Nigeria is associated with many fungal saprophytes. Rising oil spillages and pollution in Nigeria have made cultivation of affected agro-lands un-rewarding. Potentials of pig dung in mitigating crude oil pollution in agro-soils are herein studied. The objectives of this study were to characterize the fungal profile associated with wet and dry dung of pig. And to evaluate the remediating impacts of pig dung and their associated fungi on crude oil and heavy metals contents, physicochemical properties, and phytotoxicity of crude oil polluted soils. Coprophilous fungi were isolated from wet and dry dung by moist chamber technique and identified. Utisoil from Umudike was polluted with crude oil, amended with 10-40% of dry pig dung and sown with soybean (Glycine max L.). The amended and un-amended crude oil contaminated utisols were analyzed to reduce crude oil and heavy metals contents; and physicochemical properties at planting, and harvesting, respectively, using classical and spectrometric methods, and the extent of crude oil and heavy metals removal determined. The percentage germination, height, number of leaves, leaf color, vigor, and biomass of the test crop were recorded from the test plant. The results showed that Aspergillus candidus, Sclerotium sp., Absidia sp., Acremonium sp., Candida tropicalis, C. pseudotropicalis, and Rhizopus oryzae were consistently isolated from the dry dung specimen than the wet one. The results also indicated that the treatments significantly reduced the treated soils' crude oil and heavy metals contents. It revealed that values obtained for residual oil or heavy metals contents of the treated soils and crop performance were inversely and directly related to levels of soil amendment respectively. Crop performance in the amended soil remained statistically (P?0.05) higher compared to the control. Soil analyses showed that the dung treatments significantly increased the values of nitrogen, phosphorus, potassium, organic carbon, etc. in a directly proportional manner. Therefore, pig dung and their associated fungi hold strong potentials as cheap eco-friendly platforms to provide and stimulate microbial growth, hasten degradation and removal of crude oil and heavy metals from contaminated soils; and thus permit and sustain good performance of arable crops.
