Degradation of phenanthrene, fluorene, fluoranthene, and pyrene by a Mycobacterium sp.
Mycobacterium sp. strain BB1 was isolated from a former coal gasification site. It was able to utilize phenanthrene, pyrene, and fluoranthene as sole sources of carbon and energy and to degradeExpand

Measurement of the noise generation at the trailing edge of porous airfoils
Owls are commonly known for their quiet flight, enabled by three adaptions of their wings and plumage: leading edge serrations, trailing edge fringes and a soft and elastic downy upper surface of theExpand

Utilization of solubilized and crystalline mixtures of polycyclic aromatic hydrocarbons by a Mycobacterium sp.
A strain of Mycobacterium, that is able to degrade fluorene, phenanthrene, fluoranthene and pyrene was grown on various mixtures of these substrates. The polycyclic aromatic hydrocarbons (PAH) wereExpand
