For extraction, the methanolвЂ“water extraction method (1:1) was chosen. Three strains were gram-negative ( Pseudomonas aeruginosa, Escherichia coli,В and Klebsiella pneumoniae), and three were gram-positive ( Corynebacterium glutamicum, Bacillus cereus,В and Enterococcus faecalis). In this work, metabolic analyses of six bacterial strains were performed in light of three different bacterial cell disintegration methods. Metabolomic experiments usually contain many different steps, each of which can strongly influence the obtained results. This program has some very useful simulation options.Free Download specifications. Which is the flagship NMR software of MESTRELAB, the producing company.

Cereus).В This study indicated that the comparison of samples prepared by different procedures can lead to false or imprecise results, leaving an imprint of the disintegration method. FaecalisВ and tissue lyser for B. The results clearly show that one of the disruption methods gives the highest concentration for most identified compounds (e. The obtained results showed that metabolite concentrations are strongly dependent on the cell lysing methodology used and are different for various bacterial strains. For bacterial extract metabolite analysis, 1H NMR together with univariate and multivariate analyses were applied.

It was successfully used to analyze bacterial cell adaptation, microorganism identification, and phage infection mechanisms 1. Presented results can be significant for all types of microbial studies containing the metabolomic targeted and non-targeted analysis.The analysis of cell metabolite compositions and concentrations (metabolomics) is a rapidly developing research tool. The results of multivariate data analyses (PCA) show that regardless of the disintegration method used, the strain group can be identified. Some metabolites were identified by the 1H NMR method in only one strain. In addition to disintegration method comparison, the metabolic profiles of each elaborated strain were analyzed, and each exhibited its metabolic profile.

This situation may be confusing for scientists starting their adventure with metabolomics. The metabolite extraction efficiency determines the amount of biomass required for the experiment, which may cause problems due to low biomass yields for certain species of microorganisms 3, 4.Methods used in sample preparation differ depending on reported research (Table 1). Analytical technologies used in metabolomics include mainly chromatography coupled with mass spectrometry (MS) or nuclear magnetic resonance (NMR).Due to the low concentration of metabolites (approximately 2% of cell dry mass) and detection limits of analytical techniques, the investigation of intracellular metabolites usually requires initial extraction and concentration.

Due to lipid solubility in organic solvents, most metabolite extraction protocols use organic solvents such as methanol, chloroform, or ethanol. The membrane is relatively susceptible to disruption with chemical agents such as organic solvents or detergents 22, 23, and it is not an effective barrier for hydrophobic molecules. It may be passively passed by small uncharged or nonpolar molecules (water, carbon dioxide or hydrogen, protonated organic acids).

Bacteria are classified as gram-positive or gram-negative. Faecalis may be explained by bacterial cell wall resistance and structure. It is known that cell wall disruption affects the metabolomic profile obtained of bacteria and the effect is much stronger in the case of gram-positive Enterococcus faecalis than for gram-negative Escherichia coli 22, 24.The more substantial effect of cell wall disruption in the case of E. Passive diffusion through the cell wall is possible for globular molecules up to 25В kDa 24. The cell wall is resistant to disintegration with chemical solvents, however, it is not as an effective barrier for soluble molecules as lipid membrane.

In Escherichia coli the peptidoglycan layer is flexible net, and its thickness is between 2.5 and 6В nm 25. In the case of gram-negative bacteria, the layer of peptidoglycan is localized in the periplasmatic space and is relatively thin. The bacterial cell wall is mainly composed of the peptidoglycan polymer, which is also known as murein.

The cell wall is composed of long murein cables wrapped around the cell along the longer axis. In the case of Bacillus subtilis the cell wall organization is more sophisticated. The thickness of this structure is around 25В nm 28. In species like Staphylococcus aureus murein still resembles a net composed of relatively short amino sugar strands (6 disaccharide units on average) 27. In gram-positive bacteria, only one lipid membrane is present, and the outer peptidoglycan layer is thicker.

Subtilis it is around 100В MPa, respectively. The pressure required to destroy the cell wall in Staphylococcus aureus is around 250В MPa, and in B. The cell wall of gram-positive species, in general, is regarded as tough.

An adequately prepared protocol is more reliable and can be useful. Better disruption requires harsh conditions or longer time 26, 30.In metabolomics studies, each step of the sample preparation influences results. The efficiency of the cell disruption process depends on the amount of energy delivered to the system. Freezing causes the formation of water crystals inside cells, resulting in volume extension and cell disruption. During milling, cells are squeezed and damaged during collisions with bead particles and vessel walls.

Three strains were gram-negative bacteria ( Pseudomonas aeruginosa DSMZ 1707, Escherichia coli ATCC 9212, and Klebsiella pneumoniae ATCC 700603), and three were gram-positive bacteria ( Enterococcus faecalis ATCC 29212, Bacillus cereus ATCC 11778, and Corynebacterium glutamicum ATCC 13287).In the first step, the strains were routinely grown on MillerвЂ™s LB broth agar (BioShop) with 0.5% glucose (BioShop) (Behrends, 2013), which provided growth suitable for the collection of the inoculum.To evaluate the differences between strains, bacteria were cultured in 10В cm Petri dishes for 24В h at 37В вЊ. These factors may influence cell mechanical resistance and metabolite extraction procedure efficiency.In this study, six strains were analyzed. Bacteria species selection was based on their difference in cell wall structure and shape.
