sp. nov., a Gram-positive mesophilic bacterium isolated from plant lesions.

A bacterial strain was isolated from pathogenic lesions of tree leaves from the Teutoburg Forest in North Rhine-Westphalia, Germany, by culture on non-selective agar plates. 16S rRNA sequencing revealed 100% similarity to and , as well as 99% similarity to and . Here, we used genome-based taxonomy with the Type (Strain) Genome Server (TYGS), which suggests the isolation of a novel prokaryotic strain.

Genome-Based Analysis of Virulence Factors and Biofilm Formation in Novel Strains Isolated from Household Appliances.

In household washing machines, opportunistic pathogens such as are present, which represent the household as a possible reservoir for clinical pathogens. Here, four novel strains, isolated from different sites of household appliances, were investigated regarding their biofilm formation. Only two isolates showed strong surface-adhered biofilm formation.

Clusters Toxic Nickel Nanoparticles to Enhance Survival.

Microorganisms forming a biofilm might become multidrug-resistant by information exchange. Multi-resistant, biofilm-producing microorganisms are responsible for a major portion of hospital-acquired infections. Additionally, these microorganisms cause considerable damage in the industrial sector.

Magnetron Sputtering of Transition Metals as an Alternative Production Means for Antibacterial Surfaces.

In the light of the SARS-CoV-2 pandemic and growing numbers of bacteria with resistance to antibiotics, the development of antimicrobial coatings is rising worldwide. Inorganic coatings are attractive because of low environmental leakage and wear resistance. Examples for coatings are hot metal dipping or physical vapor deposition of nanometer coatings.

Bacterial Biofilm Formation on Nano-Copper Added PLA Suited for 3D Printed Face Masks.

The COVID-19 Pandemic leads to an increased worldwide demand for personal protection equipment in the medical field, such as face masks. New approaches to satisfy this demand have been developed, and one example is the use of 3D printing face masks. The reusable 3D printed mask may also have a positive effect on the environment due to decreased littering.

Identification of Microorganisms from Several Surfaces by MALDI-TOF MS: Is Leading in Biofilm Formation.

New ecological trends and changes in consumer behavior are known to favor biofilm formation in household appliances, increasing the need for new antimicrobial materials and surfaces. Their development requires laboratory-cultivated biofilms, or biofilm model systems (BMS), which allow for accelerated growth and offer better understanding of the underlying formation mechanisms. Here, we identified bacterial strains in wildtype biofilms from a variety of materials from domestic appliances using matrix-assisted laser desorption/ionization-time of flight mass spectroscopy (MALDI-TOF-MS).

Natural and synthetic nanopores directing osteogenic differentiation of human stem cells.

Bone regeneration is a highly orchestrated process crucial for endogenous healing procedures after accidents, infections or tumor therapy. Changes in surface nanotopography are known to directly affect the formation of osteogenic cell types, although no direct linkage to the endogenous nanotopography of bone was described so far. Here we show the presence of pores of 31.
