TL;DR: Bacterial biofilms of a mutant of E. coli, deficient in sigma(s), were impaired in developing LSMMG-conferred resistance to the general stressors but not to the antibiotics, indicating two separate pathways of LS MMG- Conferred resistance.

TL;DR: A trend relating cell motility to experimental outcome is identified and related studies conducted in microgravity analog devices, such as the clinostat or rotating wall vessel bioreactor, further corroborate this trend.

TL;DR: The results strongly suggest a dual mechanism for the wild-type biofilm penicillin G resistance, retarded penetration, and effective efflux.

TL;DR: Microbial antibiotic production was examined onboard the International Space Station during the 72-day 8A increment and findings of increased productivity of actinomycin D by Streptomyces plicatus in space corroborated with previous findings for the early sample points; however, the flight production levels were lower than the matched ground control samples for the remainder of the mission.
