Effect of preservation method on the assessment of bacterial community structure in soil and water samples.
The methods used in sample preservation may affect the description of the microbial community structure by DNA-based techniques. This study aims at evaluating the effect of different storage conditions, including freezing, adding two liquid-based preservatives or simply storing samples with no preservative, on the structure of the microbial communities in aliquots of organic-rich soil and water...
متن کاملGround Water Issue: Mineralogical Preservation of Solid Samples Collected from Anoxic Subsurface Environments October 2006
Remedial technologies utilized at hazardous waste sites for the treatment of metal and metalloid contaminants often take advantage of reduction-oxidation (redox) processes to reach ground water clean up goals (Barcelona and Holm, 1991; U.S. Environmental Protection Agency, 2002). This is because redox reactions, in many cases, govern the biogeochemical behavior of inorganic contaminants by affe...
متن کاملBoric acid preservation of urine samples.
Comparison of the results of bacteriological culture and microscopic examination of urine samples transported over a distance by the dip-inoculum transport medium, ice-box, and boric acid preservation with "natural" urine specimens showed that the last, in a final concentration of 1.8%, gives satisfactory preservation.
متن کاملChemical Samples Recycling: The MDPI Samples Preservation and Exchange Project
Over the years, chemists have been known to make a significant contribution to science, and to generate new chemical substances as a result of their professional activities. Over 20 million compounds have been recorded in the literature, however, because of their use in chemical processes and their disposal in waste products, only a smaller number of these compounds are available for furture us...
متن کاملDetection and enumeration of Cryptosporidium oocysts in environmental water samples by Real-time PCR assay
Introduction: The protozoan parasite, Cryptosporidium Spp., widely spreads in both raw and drinking waters. It is the causative agents of waterborne diarrhea and gastroenteritis in the world. In the present study, a molecular assay was used for the detection and quantification of Cryptosporidium oocysts in environmental water samples. Materials and methods: Thirty surface water samples wer...
