[Ab] Resumo:Soil remediation mitigates hazards from contaminants but could deprive soils of initial biota and enzymes. Historically contaminated acidic soil from Arnoldstein (Austria) and calcareous soil from Meza (Slovenia) were washed with 30 and 100 mmol kg ethylenediaminetetraacetate (EDTA) to remove 78 and 60% of Pb as a main pollutant. Remediation of the Arnoldstein soil decreased urease activity and increased ß-glucosidase activity, measured in a 15-week experiment. The dehydrogenase activity and microbial gene abundances were not significantly impeded compared to the original soil. Conversely, the use of a high dose of EDTA in the Meza soil, necessary for effective remediation of calcareous soils, resulted in pronouncedly decreased enzyme activities (3.2 times on average) and repressed fungal ITS and increased bacterial 16S rRNA gene abundance. Remediation shifted the microbial community composition in both soils. For revitalisation, the remediated soils were amended with compost, inocula of un-contaminated soil and (Arnoldstein soil) biochar enriched with soil extract. Amendments inconsistently affected the Arnoldstein soil: compost increased the dehydrogenase activity and altered the microbial community composition, biochar enhanced the ß-glucosidase activity, and all amendments decreased the microbial abundance (1.6 times on average). In contrast, amendments efficiently revitalised the remediated Meza soil; compost and soil inoculum returned the enzyme activities back to the baseline in the original soil, increased the fungal abundance above that in the original soil and restored the microbial community composition.

[Ab] Resumo:A novel Gram-stain-positive bacterial strain, designated as K13 , was isolated from compost and characterized using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, the strain showed highest similarity (93.8 %) to Paenibacillus nanensis MX2-3 . Cells of strain K13 were aerobic, motile rods. The major fatty acids were anteiso C15 : 0 (34.4 %), iso C16 : 0 (17.3 %) and C16 : 0 (10.0 %). The major menaquinone was MK-7, the polar lipid profile included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine and an aminophospholipid. The DNA G+C content was 52.3 %. Based on phenotypic, including chemotaxonomic characteristics and analysis of the 16S rRNA gene sequences, it was concluded that strain K13 represents a novel genus, for which the name Xylanibacillus gen. nov., sp. nov. is proposed. The type species of the genus is Xylanibacillus composti, the type strain of which is strain K13 (=DSM 29793 =NCAIM B.02605 ).

[Ab] Resumo:Genetically modified (GM) cotton production generates a large yield of stalks and their disposal is difficult. In order to study the feasibility of using GM cotton stalks for composting and the changes that occur in antibiotic resistance genes (ARGs) during composting, we supplemented pig manure with GM or non-GM cotton stalks during composting and we compared their effects on the absolute abundances (AA) of intI1, intI2, and ARGs under the two treatments. The compost was mature after processing based on the germination index and C/N ratio. After composting, the AAs of ARGs, intI1, and intI2 were reduced by 41.7% and 45.0% in the non-GM and GM treatments, respectively. The ARG profiles were affected significantly by temperature and ammonia nitrogen. In addition, excluding tetC, GM cotton stalks had no significant effects on ARGs, intI1, and intI2 compared with the non-GM treatment (p < 0.05). Thus, similar to non-GM cotton stalks, GM cotton stalks can be used for aerobic composting with livestock manure, and the AAs of ARGs can be reduced. Furthermore, the results of this study provide a theoretical basis for the harmless utilization of GM cotton stalks.

[Ab] Resumo:The present study addresses the problem of organic farmers' that needs local organic resources with their enhanced quality to effectively fertilize their agriculture crops. In accordance with the objective of the experiment that is about enhancing quality of compost, a blend of organic resources, comprising cow manure (CM), poultry manure (PM) and kitchen waste (KW) (2:1:1 ratio by volume) was composted with effective microorganisms (EM.1) (CompostEM.1) and without (Compostplain). During composting, temperature, pH, carbon, nitrogen, C/N ratio, total and diethylene triamine pentaacetic acid (DTPA)-extractable essential metal micronutrient (Fe3+, Cu2+, Zn2+, and Mn2+) contents of both the composts were recorded following the standard procedures. Low temperature range (24−24), low pH (6.7−7.2) and higher N-content (1.15−1.40) were recorded for CompostEM.1 as compared to Compostplain. Carbon degradation was also faster in CompostEM.1 than in Compostplain. Consequently, C/N ratio stabilization took 6 weeks in CompostEM.1 as compared to 18 weeks in Compostplain, leading to rapid completion of composting. Total concentration of micronutrients increased while their DTPA-extractable content decreased during the composting. Total micronutrient concentration was augmented more in Compostplain samples than in CompostEM.1. However, decrease in DTPA-extractable content was similar in both the composts. Increase in micronutrient content was attributed to decrease in organic matter weight, whereas decrease in metal micronutrients was attributed to the formation of organic matter-metal complexes during decomposition. Findings of the study indicated that effective micro-organisms enhanced composting process, however, further studies are required to evaluate its quality, especially effect on plant and soil.

[Ab] Resumo:Early blight disease and fruit damage by Helicoverpa armigera are serious problems of tomato causing heavy losses in the yield. An experiment was conducted to evaluate the efficacy of talc based formulation of antagonist Pseudomonas flourescens (Psf) delivered through two different forms of substrate, farmyard manure (FYM) and vermicompost, for the management of tomato early blight disease. Two treatments of Psf, were selected Solarization of nursery soil + seeds and seedlings root dip treatment with Psf formulation + Use of FYM colonized with Psf formulation; Solarization of nursery soil + seed and seedlings root dip treatment with Psf formulation + Use of vermicompost colonized with Psf formulation. These were compared with farmer's practice and untreated control. The impact of all these treatments on tomato fruit borer, H. armigera was also studied. There was not much variation in plant growth parameters (plant height and canopy width) between all the treatments. Both biocontrol treatments (17.69% and 141.3 q acre-1; 15.70% and 139.4 q acre-1, respectively), as well as farmer's practice (10.25% and 208.5 q acre-1) were found to be better than untreated control (29.21% and 94.6 q acre-1) in reducing the incidence of early blight disease in tomato and increasing the marketable yield of tomato fruits. However, the farmer's practice was found to be significantly better than both biocontrol treatments of Psf in controlling fruit damage due to disease, as well as fruit borer. The effect of both bioagents enriched formulations i.e. FYM+Psf and vermicompost+Psf with respect to disease was significantly at par with each other, whereas they had no impact on the fruit borer incidence. The results indicated that either of biocontrol treatments of P. flourescens using farmyard manure and vermicompost, as delivery substrates, can be considered as one of the component along with chemical control in developing IPM programme for the management of early blight disease in tomato.

[Ab] Resumo:A novel thermophilic actinomycete, designated strain 3-12X , was isolated from mushroom compost in Guangxi University, Nanning, China. The novel isolate contained meso-diaminopimelic acid as the diagnostic diamino acid and the whole-cell sugars were glucose and ribose. The predominant menaquinones were MK-9(H4) and MK-9(H6). The polar phospholipids were diphosphatidylglycerol, hydroxy-phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, ninhydrin-positive phosphoglycolipids and glycolipids. Major fatty acids were so-C16 : 0 and C17 : 0. The G+C content of the genomic DNA was 74.6 %. The 16S rRNA gene sequence analysis showed that the closest phylogenetic neighbour of strain 3-12X was Thermomonospora chromogena ATCC 43196 (97.0 %), other closely related strains all belonged to the family Streptosporangiaceae and showed more than 6 % divergence. The chemotaxonomic characteristics of strain 3-12X were significantly different from Thermomonospora chromogena ATCC 43196 and DNA-DNA hybridization showed low relatedness (48.6-55.6 %) between them, so they should be different species. Thermomonospora chromogena was removed from the genus Thermomonospora by Zhang et al. 1998 on the basis of phylogenetic, chemotaxonomic and phenotypic evidence, but its taxonomic position remains uncertain. Based on the phenotypic and phylogenetic data, strain 3-12X represents a novel species in a new genus in the family Streptosporangiaceae. The name Thermostaphylospora griseoalba gen. nov., sp. nov. is proposed. The type strain of Thermostaphylospora grisealba is 3-12X (=DSM 46781 =CGMCC 4.7160 ). We also propose transferring Thermomonospora chromogenaZhang et al. 1998 to Thermostaphylospora chromogena comb. nov. (type strain ATCC 43196 =JCM 6244 ).

[Ti] Título:Composted biosolids and treated wastewater as sources of pharmaceuticals and personal care products for plant uptake: A case study with carbamazepine.

[Ab] Resumo:Irrigation with treated wastewater (TWW) and application of biosolids to arable land expose the agro-environment to pharmaceuticals and personal care products (PPCPs) which can be taken up by crops. In this project, we studied the effect of a carrier medium (e.g., biosolids and TWW) on plant (tomato, wheat and lettuce) uptake, translocation and metabolism of carbamazepine as a model for non-ionic PPCPs. Plant uptake and bioconcentration factors were significantly lower in soils amended with biosolids compared to soils irrigated with TWW. In soils amended with biosolids and irrigated with TWW, the bioavailability of carbamazepine for plant uptake was moderately decreased as compared to plants grown in soils irrigated with TWW alone. While TWW acts as a continuous source of PPCPs, biosolids act both as a source and a sink for these compounds. Moreover, it appears that decomposition of the biosolids in the soil after amendment enhances their adsorptive properties, which in turn reduces the bioavailability of PPCPs in the soil environment. In-plant metabolism of carbamazepine was found to be independent of environmental factors, such as soil type, carrier medium, and absolute amount implemented to the soil, but was controlled by the total amount taken up by the plant.

[Ti] Título:Biochar to reduce ammonia emissions in gaseous and liquid phase during composting of poultry manure with wheat straw.

[Ab] Resumo:Composting of poultry manure which is high in N and dense in structure can cause several problems including significant N losses in the form of NH through volatilization. Biochar due to its recalcitrance and sorption properties can be used in composting as a bulking agent and/or amendment. The addition of a bulking agent to high moisture raw materials can assure optimal moisture content and enough air-filled porosity but not necessarily the C/N ratio. Therefore, amendment of low C/N composting mixtures with biochar at low rates can have a positive effect on composting dynamics. This work aimed at evaluating the effect of selected doses of wood derived biochar amendment (0%, 5% and 10%, wet weight) to poultry manure (P) mixed with wheat straw (S) (in the ratio of 1:0.4 on wet weight) on the total ammonia emissions (including gaseous emissions of ammonia and liquid emissions of ammonium in the collected condensate and leachate) during composting. The process was performed in 165L laboratory scale composting reactors for 42days. The addition of 5% and 10% of biochar reduced gaseous ammonia emission by 30% and 44%, respectively. According to the obtained results, the measure of emission through the condensate would be necessary to assess the impact of the total ammonia emission during the composting process.
