The limits of life of aerobic microorganisms are well understood, but the responses of anaerobic microorganisms to individual and combined extreme stressors are less well known. Motivated by an interest in understanding the survivability of anaerobic microorganisms under Martian conditions, we investigated the responses of a new isolate, Yersinia intermedia MASE-LG-1 to individual and combined ...

As the most prevalent preservative worldwide for many years, pentachlorophenol (PCP) has attracted much interest in the study of biodegradation in soil and aquatic ecosystems. However, the key microorganisms involved in anaerobic degradation are less well understood. Hence, we used DNA-based stable isotope probing (SIP) to identify the PCP-degrading microorganisms in iron-rich paddy soil under ...

Anaerobic digestion process is one of the alternative methods to convert organic waste into methane gas which is a fuel and energy source. Activities of various kinds of microorganisms are the main factor for anaerobic digestion which produces methane gas. Therefore, in this study a modified Anaerobic Baffled Reactor (ABR) with working volume of 50 liters was designed to identify the microorgan...

To reduce the frequency and severity of bacterial infection, selective antimicrobial modulation (SAM) was applied in 39 patients with severely decreased host defense mechanisms. The objective was to eliminate potentially pathogenic aerobic microorganisms with minimal disturbance of the normal anaerobic bacterial flora. Elimination of potentially pathogenic aerobic microorganisms was easily acco...

The aim of this study was to investigate in vitro the antimicrobial activity of calcium hydroxide [Ca(OH)2] in combination with different vehicles against endodontic pathogens. For such purpose, a broth dilution test was performed. Pastes were prepared with Ca(OH)2 powder and the following vehicles: sterile water, glycerin, camphorated monochlorophenol (CMCP), CMCP + glycerin, polyethyleneglyco...

Efficient dissociation of microorganisms from their aggregate matrix is required to study the microorganisms without interaction with their native environment (e.g., biofilms, flocs, granules, etc.) and to assess their community composition through the application of molecular or microscopy techniques. To this end, we combined enzymatic treatments and a cell extraction by density gradient to ef...
