Inhibition, gene expression and modeling of ammonia oxidation in biofilms of Nitrosomonas europaea

Creator:

Lauchnor, Ellen Grace

Abstract:

This dissertation explores the physiology and gene expression of the ammonia-oxidizing bacterium Nitrosomonas europaea in surface-associated bacterial communities, or biofilms. Biofilms of N. europaea were cultivated in drip flow reactors for several weeks and gene expression microarrays were used to detect 240 genes differentially expressed between the mature biofilms and...

Factors controlling halogenated and nonhalogenated alkene growth substrate range of vinyl chloride-utilizing bacteria

Creator:

Taylor, Anne Elizabeth

Abstract:

This thesis explores the factors limiting the alkene substrate range of the vinyl chloride (VC)-utilizing bacteria, and describes a method for measuring VC transformation in situ. Vinyl fluoride (VF) was evaluated as a surrogate for monitoring aerobic VC-transformation utilizing three isolates, Mycobacterium EE13a, Mycobacterium JS60 and Nocardioides JS614. JS614 grew...
