Project description:We obtained L. kefiri (JCM5818) and L. kefiranofaciens (JCM6985) from the Japan Collection of Microorganisms (JCM). Bacteria were grown together at two different temperatures of 30C and 37C profiled for transcriptomics, metabolomics, and proteomics.
Project description:We introduce FACIL (http://www.cmbi.ru.nl/FACIL), a fast, reliable tool to evaluate nucleic acid sequences for non-standard codes that detects alternative genetic codes even in species distantly related to known organisms. Results are visualized in a Genetic Code Logo. To illustrate the use of our method, we analysed several contigs derived from the mitochondrial genome of the foraminifer Globobulimina pseudospinescens. These are particularly challenging data, as the genome is highly fragmented and incomplete. Approximately 10,000 single-cell Globobulimina pseudospinescens organisms were isolated by hand from Gullmar Fjord Sweden sediment. After washing, total DNA was extracted and sequenced by Illumina sequencing. The reads were assembled using Edena. To illustrate the use of our method, we analysed several contigs derived from the mitochondrial genome of the foraminifer Globobulimina pseudospinescens, an organism without any sequenced relatives in the databases. These are particularly challenging data, as the genome is highly fragmented and incomplete. DNA isolated from approximately 10,000 single-cell Globobulimina pseudospinescens organisms

Project description:Polyphosphate accumulating organisms are responsible for enhanced biological phosphate removal from wastewater, where they grow embedded in a matrix of extracellular polymeric substances. Little is known about the composition and dynamics of those proteins and their production by the different microorganisms. Tomás-Martínez et al., (2022) studied the turnover of proteins and polysaccharides in extracellular polymeric fractions of an enrichment culture of polyphosphate accumulating organisms using an anaerobic-aerobic sequencing batch reactor simulating EBPR conditions. Finally, the carbon source was switched to 13C-labelled acetate to study the protein turnover. Samples were collected at the end of each aerobic phase.
