Highlights
Are you wondering what gets my research group busy these days? We do many cool things, but we present in this section some highlights of our works.

You read the title correctly - herbicides from wastewater. We asked, "what if we develop a method to outsource herbicides from locally produced organic waste streams such as wastewater from various sources (commercial, residential, municipal, etc.)?" We introduce our patent-pending (currently with Provisional Patent status with US Patent Office) technology of producing herbicides of nonanoic acid from the ozone cracking of oleic acid accumulated by oleaginous microorganisms feeding on organic wastes.
Spoiler alert: Our herbicide-from-wastewater technology works, so you will see our results via paper publications and demo processing systems soon.
Research Grant: Principal Investigator (PI) - Dhan Lord B. Fortela; Production of Nonanoic Acid and Similar Herbicides via In-situ Ozone Cracking of Microbial Oils Cultivated on Organic Wastewaters, 2025-2028. Funding Agency: Louisiana Board of Regents (LA-BOR); Sub-program: Industrial Ties Research Subprogram (ITRS). Fund: US$ 301,573 (external fund from LA-BOR) + US$ 199,579 (internal fund as Co-share by UL Lafayette plus consultation services by collaborators) = US$ 501,152 total project fund.
