Nanopore sequencing for forensic short tandem repeats (STR) genotyping comes with the advantages associated with massively parallel sequencing (MPS) without the need for a high up-front device cost, but genotyping is inaccurate, partially due to the occurrence of homopolymers in STR loci. The goal of this study was to apply the latest progress in nanopore sequencing by Oxford Nanopore Technologies in the field of STR genotyping. The experiments were performed using the state of the art R9.4 flow cell and the most recent R10 flow cell, which was specifically designed to improve consensus accuracy of homopolymers. Two single-contributor samples and one mixture sample were genotyped using Illumina sequencing, Nanopore R9.4 sequencing, and Nanopore R10 sequencing. The accuracy of genotyping was comparable for both types of flow cells, although the R10 flow cell provided improved data quality for loci characterized by the presence of homopolymers. We identify locus-dependent characteristics hindering accurate STR genotyping, providing insights for the design of a panel of STR loci suited for nanopore sequencing. Repeat number, the number of different reference alleles for the locus, repeat pattern complexity, flanking region complexity, and the presence of homopolymers are identified as unfavorable locus characteristics. For single-contributor samples and for a limited set of the commonly used STR loci, nanopore sequencing could be applied. However, the technology is not mature enough yet for implementation in routine forensic workflows.

Flow cells were utilized to determine the effects of repetitive Syto9 staining on developing Acinetobacter sp. BD413 biofilm and to identify features describing reproducible biofilm architecture at 63× magnification. Syto9 is a general nucleic acid stain employed to visualize the entire microbial population of the biofilm and a component in the LIVE/DEAD® BacLight™ Bacterial Viability kits. CLSM images were quantified with the biofilm analysis software PHLIP to calculate six commonly used biofilm architecture characteristics. The characteristics biovolume and mean thickness were most reproducible when biofilms were grown in separate flow cells under controlled conditions, while roughness, porosity, total spreading and surface area to biovolume ratio exhibited inherent variability. Biovolume was more variable in separate flow cells than in channels of the same flow cell. However, even biofilms grown in channels of the same flow cell did not generate reproducible architectures based on the six characteristics. Results suggest difficulties in differentiating the effect of changes due to treatment from the natural variability of architecture development at the cellular level. Despite this high variability, biofilms only stained once developed into thicker structures containing more biomass than biofilms stained multiple times, suggesting that repeated staining with Syto9 affects architecture development. The application of Syto9 to monitor developing biofilms is not recommended.
