Alum Success

“The material covered in LSSU's engineering program provided me a solid foundation for graduate studies. The systematic approach and communication skills needed to tackle engineering projects were taught and then practiced over and over again. In particular I appreciate the many hours spent by the faculty to develop oral presentation skills in each student. As a graduate student now, these skills have proven to be highly beneficial and, to my surprise, obviously not taught to the same extent at many other universities.”

Carl & Bernitta Burtt Scholarship

This named scholarship was established by the children of Carl and Bernitta Burtt in honor of their parents to benefit a student majoring in any course of study in the College of Arts, Letters and Social Sciences. Carl Burtt was the second eldest son in a family of thirteen. He dropped out of school at the age of twelve in order to support his brothers and sisters. Although he was unable to complete his own education, he always maintained the value of a good education. Carl was an avid reader and a history buff. He enjoyed learning and made a point to pass this enjoyment on to his children. Carl married the former Bernitta Wilcox in 1944 and they had six children. Though she did not finish high school, Bernitta valued education and vowed that all of her children would complete high school and would be supported in their effort to attend college. They taught their children that an education was an asset that would always serve them well, and was something that each would keep with them for life. Recipients must be of sophomore status with a GPA of 3.0 or higher and demonstrate financial need.

  

 

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.
