'Dual-species biofilms of Streptococcus mutans and Veillonella parvula are less susceptible to antimicrobials than single-species biofilms of the same microorganisms. The microstructure of single and dual-species biofilms of S. mutans and/or V. parvula was visualized to find out whether the spatial arrangement of bacteria in biofilms is related to survival ...

Simultaneous fluorescent gram staining and activity assessment of activated sludge bacteria.
Wastewater treatment is one of the most important commercial biotechnological processes, and yet the component bacterial populations and their associated metabolic activities are poorly understood. The novel fluorescent dye hexidium iodide allows assessment of Gram status by differential absorption through bacterial cell walls. Differentiation between gram-positive and gram-negative wastewater bacteria ... More
