Murga, "Quantitative observations of heterogeneities in pseudomonas aeruginosa biofilms," Appl. Envir. Microbiol., 59(1):327-329 (1993).0099-2240https://scholarworks.montana.edu/handle/1/13146Heterogeneity in a Pseudomonas aeruginosa biofilm was quantified by measuring distributions of thickness in biofilm samples and a distribution of particle sizes in effluent samples. The mean steady-state thickness was approximately 33 ,um, but individual measurements ranged from 13.3 to 60.0 Mm. Particles exceeding 100 ,um3 were observed in the reactor effluent. The results reveal a rough biofilm surface and indicate that most biomass detaches in the form of multicellular particles.Article
