1) The document discusses analytical tools and technologies used by UT/OpenAlgae to analyze lipids extracted from algae, including thin layer chromatography, HPLC/MS, and GC/MS. These tools can measure individual lipid classes and fatty acids throughout growth and processing.
2) Preliminary results from a study on a commercially available omega-7 product suggest it accelerates wound closure and improves blood flow and scar formation in wounded sheep. UT has identified an algae that produces high quantities of omega-7.
3) UT is conducting a pilot project to test using processed algae biomass as fertilizer, measuring effects on plant growth and soil properties.
Development and method validation for determination of Deltamethrin residue i...IOSR Journals
Olive oil is the most important commodities produced in the Mediterranean region. Due to its significant economical importance, the usage of pesticides in its production is systematic, by using a wide range of plant protection products with a variety of modes of action. As a consequence, monitoring of their residue levels in these products is a necessity. In the present study a reversed-phase high performance liquid chromatography method, with a short sample preparation step, based on acetonitrile extraction is developed and validated in olive oil, with a large scope that includes Deltamethrin as pesticide. Good sensitivity and selectivity of the method were obtained with limits of quantification at 0.2 mg kg-1. Deltamethrin has recovery rate which is of about 80℅. We confirm also the efficiency of alumina, used as adsorbent in the clean up step, to remove triglycerides and to get a pure extract. The agronomic implementation of this protocol allows us to determine the influence of some parameters on the dose and the period of treatment affecting the detected quantities of Deltamethrin residues in the produced olive oil. Indeed, we prove that the treatment dose should be specific for each case considering the olive variety, the geography of the orchard, and the predicted harvest time to determine the convenient dose of treatment. In addition, the results show that the preventive treatment at the blooming phase, does not lead to the concentration of Deltamethrin residues in the oil as it happens at the lipogenesis phase.

Alfa Chemistry has been a leading provider of analytical testing and research services in the global food industry for decades. It now provides food testing services.
Environmental analysis can be extremely challenging due to the low detection levels for toxic contaminants specified by legislation, particularly in drinking water, and the complexity of matrices encountered. Consequently highly selective and sensitive detection methods are required. This presentation provides an introduction to tandem quadrupole mass spectrometry and describes the use of high sensitivity tandem quadrupole mass spectrometry for the analysis of various environmental contaminants including pesticides, endocrine disruptors and polyfluorinated compounds such as PFOS.

2. Standard Measurement Technologies Nile Red is the current measurement tool of choice in the algae industry Here’s what Nile red measures: lipophilic molecules Here’s an example of how Nile red measurements can mislead algae growers: Nile red measurements may indicate that both of these samples has 30% “oil”
4. UT/OpenAlgae Technologies – Thin Layer Chromatography Samples are taken before and after each processing step. Each sample is separated into a biomass pellet (P) and supernatant (S) fraction and analyzed by TLC against known standards.
