Organization of methylamine utilization genes (mau) in 'Methylobaccillus flagellatum' KT and analysis of mau mutants
Article Abstract:
An analysis of a set of chemically induced and insertional methylamine utilization (mau) gene mutants was conducted to determine the organization of mau genes in Methylobacillus flagellatum KT. Results reveal that the organization of the mau gene cluster in M. flagellatum KT is very similar to that in Methylophilus methylotrophus W3A1-NS. Furthermore, results show that the ability of mau mutants of M. flagellatum KT to utilize amines as sources of nitrogen indicates that MADH is not the only amine-oxidizing system in this bacterium.

Diffusion through agar blocks of finite dimensions: a theoretical analysis of three systems of practical significance in microbiology
Article Abstract:
The diffusion equations, experimental limitations for some useful cases and computer simulations for cases which cannot be considered analytically are presented for the kinetics of diffusion of a substance through a gel. Three single-diffusion conditions were examined. These are: systems for the investigation of chemotaxis in the gliding bacterium Myxococcus xanthus, the development of the gradient plates, and the application to antimicrobial disk susceptibility tests.
