Genomic And Molecular Analysis Of The Exopolysaccharide Production In The Bacterium Thauera Aminoaromatica Mz1t, Ke Jiang

Doctoral Dissertations

Thauera aminoaromatica MZ1T is an exopolysaccharide (EPS)-producing Gram negative bacterium isolated from the wastewater treatment plant of a major industrial chemical manufacturer as the causal agent for poor sludge dewatering. It shares common features with other known Thauera spp. (i.e. Thauera aromatica, and Thauera selenatis), being capable of degrading aromatic compounds anaerobically and using acetate and succinate as carbon sources. It is unique among the Thauera spp. in its production of abundant EPS which results in viscous bulking and poor sludge dewaterability. In this respect, it is similar to Azoarcus sp. EbN1 and BH72. Thaueran is the proposed …

A Multidisciplinary Approach To Food Safety Evaluation: Hummus Spoilage And Microbial Analysis Of Kitchen Surfaces In Residential Child Care Institutions (Rcci) In Massachusetts, U.S.A., Elsina E. Hagan

Masters Theses 1911 - February 2014

Food borne illnesses continues to be a public health challenge in the United States (U.S.); an estimated 9.4 million incident cases occurred in 2011. In view of this challenge we conducted two food safety studies; 1) related to product formulation (hummus spoilage challenge study) and 2) evaluating the microbial safety of domestic kitchen surfaces in Residential Child Care Institutions (RCCI pilot study).

Hummus is of Mediterranean origin but is currently eaten globally. This challenge study evaluates a variety of industrial hummus formulations (four in total, differing in pH and/or addition of a preservative (natamycin). Two batches were setup: batch 1; …
