چکیده
Abstract Lipids are among the organic substances that can work as biosignatures, indicating life in an environment. We present experimental investigation concerning analysis of lipids from a microbial source deposited on Mars Global Simulant (MGS-1) regolith by geomatrix-assisted laser desorption/ionization-mass spectrometry (GALDI-MS). Our results indicate intact cells black yeast strain be detected these mimetic samples Martian soil. These lipid molecules predominantly associated with occurrence adducts GALDI-MS spectra. The helpful planning future planetary missions.

Analysis of microbial mixtures by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
Many different laboratories are currently developing mass-spectrometric techniques to analyze and identify microorganisms. However, minimal work has been done with mixtures of bacteria. To demonstrate that microbial mixtures could be analyzed by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), mixed bacterial cultures were analyzed in a double-blind fashion. Nine differ...
متن کاملStudy of latent fingermarks by matrix-assisted laser desorption/ionisation mass spectrometry imaging of endogenous lipids.
Identification of suspects via fingermark analysis is one of the mainstays of forensic science. The success in matching fingermarks, using conventional fingermark scanning and database searching, strongly relies on the enhancement method adopted for fingermark recovery; this in turn depends on the components present in the fingermarks, which will change over time. This work aims to develop a ro...
متن کاملLaser desorption mass spectrometry for microbial DNA analysis.
Recently, we demonstrated that a matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI-TOF MS) can be used to determine the molecular weight of polymerase chain reaction (PCR) products of intact 16S rRNA regions and to profile their restriction digests. This is the first time that MALDI-TOF MS with ultraviolet (UV) photoionization has been used to analyze a PCR pro...
متن کاملAnalysis of oligonucleotides by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
MALDI-MS is one of the most useful techniques available for determining biomolecule mass. It offers high mass accuracy, good sensitivity, simplicity, and speed. Because singly charged ions of oligonucleotides are typically observed, MALDI-MS spectra are easy to interpret. This unit presents protocols for sample preparation and purification, matrix preparation, and matrix/analyte sample preparat...
متن کاملAnalysis of minor hemoglobins by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
BACKGROUND Hemoglobin (Hb) heterogeneity arises mainly from posttranslational modifications of the globin chains, and cation-exchange chromatography reveals falsely increased concentrations of some minor Hbs in the presence of abnormal Hbs. Here we describe a method for identification of the globin chains and their posttranslational modifications contained in the Hb fractions. METHODS We used...
