Filamentary Flows and Clump-fed High-mass Star Formation in G22 [PDF]

open access: yesProceedings of the International Astronomical Union, 2017
AbstractG22 is a hub-filament system composed of four supercritical filaments. Velocity gradients are detected along three filaments. A total mass infall rate of 700 M⊙ Myr−1 would double the hub mass in about three free-fall times. The most massive clump C1 would be in global collapse with an infall velocity of 0.26 km s−1 and a mass infall rate of 5 ×

Purification, characterization and cloning of a chitinase from Stenotrophomonas rhizophila G22 [PDF]

open access: yes3 Biotech, 2019
In the presented research the extracellular chitinase of Stenotrophomonas rhizophila G22 was biochemically and molecularly characterized. The studied enzyme was purified from a 72-h bacterial culture about 14 times, with a recovery of 63%. The molecular weight of the purified protein was estimated at 50 kDa by SDS-PAGE.
