| The aim of this study was to identify effects of carbonized organic material (‘‘biochar’’) on soybean growth, root nodulation and biological nitrogen fixation, and to elucidate possible underlyingmechanisms.Soybean (Glycine max L.) was grown in four arable soils amended with carbonized organic material produced from wood or maize as feedstocks, by pyrolysis (‘‘pyrochar’’) or hydrothermal carbonization (‘‘hydrochar’’). Nodulation by Bradyrhizobium, biological nitrogen fixation (BNF) assessed by15N techniques, plant growth, nutrient uptake and changes in chemical soil propertiesafter soil amendment were determined. Data were analyzed by means of a three way ANOVA onthe factors soil, carbonization technique and feedstock. It turned out that soybean root... |

| Pathogenic enteric bacteria are a major cause of drinking water related morbidity and mortality in developing countries. Solar disinfection (SODIS) is an effective means to fight this problem. In the present study, SODIS of two important enteric pathogens, Shigella flexneri and Salmonella typhimurium, was investigated with a variety of viability indicators including cellular ATP levels, efflux pump activity, glucose uptake ability, and polarization and integrity of the cytoplasmic membrane. The respiratory chain of enteric bacteria was identified to be a likely target of sunlight and UVA irradiation. Furthermore, during dark storage after irradiation, the physiological state of the bacterial cells continued to deteriorate even in the absence of... |

| Results › Carbon mineralization rates were highest in maize straw and lowest in pyrochar amended soil. › Pyrochar showed even lower CO2 fluxes than non-amended soil. › Initial mineralization rates of maize straw and hydrochar were higher in soil M, whereas in Soil D the pyrochar was decomposed slightly faster. › Hydrochar derived carbon was readily incorporated in the microbial biomass of both soils, pyrochar resisted nearly completely. › Comparison of carbon pools CO2 , Cmic and Corg at day 12 and day 205 shows that a stabilsation of maize feedstock of more than a double could be achieved with HTC and far beyond that scale with pyrolysis. |
