Giant pandas consume different structural parts of bamboo (shoots, leaves and culms) during different seasons. Previous research showed different bamboo parts have varying nutritional content and that a long-term diet consisting of a single part of bamboo resulted in remarkable metabolic changes within captive giant pandas. However, the effects on the gut microbiome of giant pandas, as a result of a single bamboo part diet, ha...

Summary The cyclohexane derivative cis ‐2‐(carboxymethyl)cyclohexane‐1‐carboxylic acid [(1 R ,2 R )‐/(1 S ,2 S )‐2‐(carboxymethyl)cyclohexane‐1‐carboxylic acid] has previously been identified as metabolite in the pathway of anaerobic degradation of naphthalene by sulfate‐reducing bacteria. We tested the corresponding CoA esters of isomers and analogues of this compound for conversion in cell free extracts of the anaerobic naph...

Summary Nitrite‐oxidizing bacteria of the genus Nitrospira are ubiquitous in natural ecosystems and also in wastewater treatment plants. Nitrospira are members of a distinct phylum, not closely related to other nitrifiers, and no genomic sequences from this genus have been available so far. Here we applied an environmental genomics approach to sequence and assemble a 137 kbp‐long genome fragment of ‘ Candidatus Nitrospira defl...

Recently, anaerobic ammonium‐oxidizing bacteria (AAOB) were identified by comparative 16S rDNA sequence analysis as a novel, deep‐branching lineage within the Planctomycetales . This lineage consists currently of only two, not yet culturable bacteria which have been provisionally described as Candidatus ‘Brocadia anammoxidans’ and Candidatus ‘Kuenenia stuttgartiensis’. In this study, a large fragment of the rDNA operon, includ...
