Journal ArticleDOI
Optimizing and calibrating a mode-mismatched thermal lens experiment for low absorption measurement
TL;DR: In this article, a two-beam mode-mismatched thermal lens experiment aimed at determination of the absorption coefficient and the photothermal parameters of a nearly transparent material is described.
Journal ArticleDOI
Potential role of oxidative exoenzymes of the extremophilic fungus Pestalotiopsis palmarum BM-04 in biotransformation of extra-heavy crude oil.

TL;DR: The aims of this work were to study the ability of Pestalotiopsis palmarum to synthesize OE, its potential to biotransform EHCO and to survive in extreme environmental conditions, and to suggest that P. palmarum BM‐04 is a hopeful alternative to be used in remediation processes inextreme environmental conditions of salinity and EH CO contamination, such as the drilling waste from the OOB.
Journal ArticleDOI
Characterization of Xenorhabdus and Photorhabdus bacteria by Fourier transform mid-infrared spectroscopy with attenuated total reflection (FT-IR/ATR)
TL;DR: The use of Fourier transform mid-infrared spectroscopy with attenuated total reflection for characterizing entomopathogenic bacteria from genera Xenorhabdus and PhotorhabDus is evaluated for the first time and showed to be a useful tool for classification purposes.
Journal ArticleDOI
ATR/FTIR characterization of Steinernema glaseri and Heterorhabditis indica
Ernesto San-Blas,Mayamaru Guerra,Edgar Portillo,Iván Esteves,Néstor Cubillán,Ysaias Alvarado +5 more
TL;DR: The use of Fourier transform mid-infrared spectroscopy with attenuated total reflection for characterizing entomopathogenic nematodes is evaluated for the first time and some important components were identified including triglycerides, trehalose, glycogen and collagen.
Journal ArticleDOI
Fourier-transformed infrared spectroscopy: a tool to identify gross chemical changes from healthy to yellow band disease tissues.
TL;DR: This study is the first to show that healthy and YBD-compromised tissues have different infrared absorption profiles, suggesting that alterations in the biochemical composition occur during pathogenesis.
