The objective of this research is to investigate best practice initiatives of sustainability involved in the successful development and management of Hamanasi Resort, an award winning eco-tourism resort located in Belize. The four phases of research at Hamanasi as originally proposed, found in Part I of the thesis, are outlined as follows: Phase one includes hands-on research through shadowing in different hotel departments, observation of management practices in Hamanasi, interviews conducted with employees, and questionnaires administered to guests; Phase two begins a study of the business and organizational model of Hamanasi along with an examination of the critical issues encountered …


A Messenger Molecule Governs Interdependency In An Evolved Pseudomonas Aeruginosa Biofilm Community, Thomas Macelliott Johnson Jan 2011

A Messenger Molecule Governs Interdependency In An Evolved Pseudomonas Aeruginosa Biofilm Community, Thomas Macelliott Johnson

Honors Theses and Capstones

Biofilm populations are known to harbor great diversity, but the importance of this diversity is not fully understood. A likely contributor to this variation is the second messenger molecule cyclic-di-GMP: low levels associate with a planktonic lifestyle while high levels favor biofilm formation. In ongoing studies of an evolving biofilm population of Pseudomonas aeruginosa (PA), we observed extensive ecological diversification that may relate to this lifestyle switch. In PA, the gene bifA encodes a phosphodiesterase that is known to degrade cyclic-di-GMP and reduce biofilm. This gene was cloned onto a plasmid under control of an inducible promoter and the plasmid …
