Airborne bacteria were measured when a dust storm passed Beijing in spring 2012 with a focus on cell concentration, viability and TSA- and R2A-cultured strain composition. The concentration varied at an order of 107cells/m3 with dust loading (demonstrated with PM10) and they had a very close correlation (RT2=0.91, p<0.01). At the time of highest PM10 of 652μg/m3, the bacterial concentration reached...
Lignin is both the most abundant aromatic (phenolic) polymer and the second most abundant raw material. It is degraded and modified by bacteria in the natural world, and bacteria seem to play a leading role in decomposing lignin in aquatic ecosystems. Lignin-degrading bacteria approach the polymer by mechanisms such as tunneling, erosion, and cavitation. With the advantages of immense environmental...
