Alum Success

“I chose LSSU expecting a very good engineering education. What I didn’t expect was faculty with real-world engineering experience and abilities, labs with real-world equipment, projects with real-world outcomes, and an entire campus staff with real interest in my success, as a student and yet today. My LSSU engineering education has created or supported every desired career opportunity. LSSU was absolutely the right place for me.”

Project Description: Design and Simulate Noise Abatement System

Team NVHM( Noise Vibrations and Harshness Management) will propose and evaluate noise control measures to mitigate the community noise footprint of the Essar Steel Mill in Sault Ste. Marie, Ontario. The project will begin with measurements to establish and prioritize predominant noise sources at the Essar site. Subsequently, engineering solutions will be recommended, their performance in terms of decibel reduction projected, and cost-benefit analyses of these provided.

Character- ization of Yellow Pigments in Freshwater Flavo- bacteria

Ashley Ryckman

The yellow color of Flavobacteria is due to the presence of carotenoids and flexirubin-type pigments. These complex chemical structures have shown to produce antioxidant properties, as well as antibacterial activity. The KOH test and reverse-phase high performance liquid chromatography (HPLC) was used to characterize carotenoid and flexirubin pigment production in three strains of Flavorbacteria: FR 87, FR Y, and FR 93. Optimization of pigment and separation was performed by quant-prep HPLC. Separation of four pigment fractions from each strain was attained using semi-prep HPLC. Antibacterial activity of the pigment fractions was tested using a MTT Assay. Fexirubin biosynthesis genes, darA and darB, of related pigment producing Flavobacteria were used to compare flexirubin pigments in FR 87. The three strains were determined to produce the carotenoid, Zeaxanthin. FR 87 produced 13 flexirubin pigments, FR Y produced 14 flexirubin pigments and FR 93 produced 20 flexirubin-type pigments. It was determined that compounds in all three strains demonstrated antibacterial activity. The flexirubin biosynthesis gene, darA, is 89.9% similar to Flavobacterium johnsoniae, and 73.2% similar to Flavobacterium psychrophilum.
