Dissimilatory phosphite oxidation (DPO), a microbial metabolism by which phosphite (HPO32−) is oxidized to phosphate (PO43−), is the most energetically favorable chemotrophic electron-donating process known. Only one DPO organism has been described to date, and little is known about the environmental relevance of this metabolism. In this study, we used 16S rRNA gene community analysis and genome-resolved metagenomics to characterize anaerobic wastewater treatment sludge enrichments performing DPO coupled to CO2reduction. We identified an uncultivated DPO bacterium,CandidatusPhosphitivorax (Ca.P.) anaerolimi strain Phox-21, that belongs to candidate order GW-28 within theDeltaproteobacteria, which has no known cultured isolates. Genes for phosphite oxidation and for CO2reduction to formate were found in the genome ofCa.P. anaerolimi, but it appears to lack any of the known natural carbon fixation pathways. These observations led us to propose a metabolic model for autotrophic growth byCa.P. anaerolimi whereby DPO drives CO2reduction to formate, which is then assimilated into biomass via the reductive glycine pathway.

The report surveys in two parts the development of the law on project-related planning and thus relates in particular to the planning and approval of space-consuming infrastructure projects such as traffic routes and power lines. For this purpose, German administrative law has long provided for the specific instrument of plan approval (Planfeststellung). In this context, the Federal Administrative Court has extensive first-instance jurisdiction and uses this to shape large parts of German approval law, including beyond the actual area of plan approval law, be it in terms of legal protection and procedure, be it with regard to the requirements of substantive environmental law. On the other hand, the revision of the law on environmental protection induced by the decisions of the Aarhus Compliance Committee and the European Court of Justice has been used by the German legislator to extend procedural specifics of the plan approval to other approval decisions of environmental relevance. This firstly indicates the contours of a general law on project approval and, secondly, the nature of the plan approval as an instrument for the implementation of projects in the public interest is more strongly emphasized.

Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing the pros and cons of soilless culture and growing media constituents, the exploitation of different organic materials and their economic and environmental relevance.
