Abstract The impact of tannery sludge application on soil microbial community and diversity is poorly understood. We studied the microbial community in an agricultural soil following two applications (2006 and 2007) of tannery sludge with annual application rates of 0.0, 2.3 and 22.6 Mg ha -1.The soil was sampled 12 and 271days after the second (2007) application. Community structure was assessed via a phospholipid fatty acid analysis, and the physiological pro?le of the soil microbial community via the Biolog method. Tannery sludge application changed soil chemical properties, increasing the soil pH and electrical conductivity as well as available P and mineral N concentrations. The higher sludge application rate changed the community structure and the physiological pro?le of the microbial community at both sampling dates.However,there is no clear link between community, structure and carbon substrate utilization.According to the Distance Based Linear Models Analysis, the fatty acids 16:0 and i17:0 together contributed 84% to the observed PLFA patterns,whereas the chemical properties available P,mineral and pH together contributed 54%. At 12 days, tannery sludge application increased the average well color development from 0.46 to 0.87 after, 48 h,and educed the time elapsed before reaching midpoint carbon substrate utilization (s) from 71 to 44 h, an effect still apparent nine months after application of the higher sludge application rate.The dominant signature fatty acids and kinetics)were correlated to the concentrations of available P, Ca, mineral N, pH and EC.

The aim of this study was to determine the physicochemical composition and inorganic constituents of seventeen honey samples produced in Amazon region by different bee species (Scaptotrigona sp., Melipona fasciculata, Melipona flavolineata and Apis mellifera). The physicochemical parameters evaluated were pH, acidity, soluble solids, moisture, density, reducing sugars, apparent sucrose and hydroxymethylfurfural. Ba, Ca, Cd, Cu, Fe, Mg, Mn, P, Pb and Zn contents were determined in honey samples by inductively coupled plasma optical emission spectrometry. Na and K contents were measured in honeys by flame atomic absorption spectrometry. Honey samples were digested in a microwave oven using diluted nitric acid and hydrogen peroxide. The analytical results obtained in this study were evaluated by analysis of certified reference material (GBW 07604 Poplar leaves). The results of physicochemical analyzes showed significant differences (p < 0.05) among the species, mainly regarding moisture content, acidity, density and soluble solids. In general, the honeys from Scaptotrigona sp. showed the highest levels of minerals (Ca, Cu, K, Mg), being a good source of minerals, as well as presented significant differences (at 5% of significance) in relation to the other studied species. Thus, the results indicate new information about the composition of these honeys and emphasize the need for the implementation of specific legislation for quality assessing of honey from stingless bees. |
