Identification and classification of antifouling compounds secreted by anti MIC microorganisms. A metabolomic analysis.

BIOCORIN project, aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion control. Some of the results of this project are presented here, with the identification of several relevant antifouling compounds secreted by environmentally isolated anti-MIC strains of microorganisms via a metabolomic approach.

Enhanced method development capabilities with automated SPME extraction optimization

A workflow has been described enabling the automated selection of the most suitable extraction conditions (type of fiber, extraction time and temperature) for the GC/MS analysis of a number of contaminants in oil and water samples.
Applying the automated workflow described above the total time to identify the most suitable fiber and then optimize conditions was 4.5 days. Compared to performing the experiments manually which is estimated at 15 days this represents of time saving of 10 days.

Analysis of Fruit Commodities by GC-TOFMS and GCxGC-TOFMS Using QuEChERS Approach

The availability of fruit commodities from a wide variety of sources has increased the need for rapid and accurate screening for pesticides in fruit. Not all fruit commodities are brought to market under the strict guidelines of the United States Department of Agriculture. Determining whether or not the Environmental Protection Agency tolerances for various pesticides have been violated is important in the risk assessment for consumers in the United States.

Analysis of Pesticide Residues in JonaGold Apples Using QuEChERS Approach and Comprehensive Two-Dimensional Gas Chromatography Time-of-Flight Mass Spectrometry (GCxGC-TOFMS)

Screening and quantitation of pesticide residues in fruits and vegetables is of utmost importance for public health and safety concerns. These commodities can contain hundreds-to-thousands of analytes, making them extremely difficult for the screening and accurate quantitation of pesticide residues.

Detection and Identification of Dispersants (COREXIT® 9527 and 9500) by GC/MS and LC-MS/MS

Dispersants are plasticizers commonly used to prevent clumping and help dissipate oil slicks. In this work, we used GC/MS and LC-MS/ MS to detect and indentify two of the most widely used dispersants (Corexit 9527 and 9500).

Detection of Environmental Contaminants Caused by the Oil Spill in the Gulf of Mexico by GC and HPLC

In order to help understand the impact that the oil spill has caused, laboratories are looking for rapid and robust analytical procedures to characterize the hydrocarbon contaminants. This work provides SPE, GPC, GC-FID, GC/MS, and HPLC analytical methods for analyzing the most common contaminants that originated from the leak.

AN INTEGRATED 1H NMR, GC-MS AND HPLC-(ESI/TOF) BASED METABOLOMICS APPROACH TO THE STUDY OF ACUTE EXERCISE IN HUMAN SERUM METABOLOME

There is an increasing concern about the different response and effect that acute exercise induces on diabetic people and a novel insight into this effect can be performed using a metabolomic approach. Metabolomic is becoming widely spread used as a new and powerful tool for discerning significant changes at metabolic level. In this study we aimed to perform a non-targeted analysis and to identify metabolic differences arisen after 30 minutes of acute exercise in both young men suffering from Ty

Temporal Dynamics of Pathogenesis Related Metabolites and their Metabolic Pathways Following Inoculation of Potato Leaves with Phytophthora infestans

The resistance in potato cultivars against late blight caused by Phytophthora infestans is classified into vertical and horizontal. Several metabolites associated with resistance have been detected: phytoalexins such as rishitin, phytuberin, lubimin, solavetivone etc. Metabolite profiling is a novel technology for the discrimination of quantitative resistance in plants against pathogen stress.
