Optimal Bacterial DNA Isolation Method Using Bead-Beating Technique
نویسندگان
چکیده
Extraction of nucleic acids from Gram-positive bacteria is normally hampered by a thick and resistant cell wall. This paper presents procedures based on mechanical cell breakage to extract DNA from Staphylococcus aureus. The proposed system for DNA extraction involves bead-beating treatment and the GES method. These two steps allow a consistent extraction from the bacterium resistant to the GES method alone. Yield and quality of DNA obtained with the proposed method were higher than those obtained with the GES method alone. This protocol can be extended to clinical specimens.

Optimal DNA isolation method for detection of bacteria in clinical specimens by broad-range PCR.
Broad-range amplification of bacterial DNA from clinical specimens has proved useful for the diagnosis of various bacterial infections, especially during antimicrobial treatment of the patient. Optimal sample processing protocols for diagnostic broad-range bacterial PCR should release DNA from an array of target organisms with equal efficiencies and wash out inhibitory factors from various samp...
متن کاملEffect of DNA extraction and sample preservation method on rumen bacterial population.
The comparison of the bacterial profile of intracellular (iDNA) and extracellular DNA (eDNA) isolated from cow rumen content stored under different conditions was conducted. The influence of rumen fluid treatment (cheesecloth squeezed, centrifuged, filtered), storage temperature (RT, -80 °C) and cryoprotectants (PBS-glycerol, ethanol) on quality and quantity parameters of extracted DNA was eval...
متن کاملMiniaturized bead-beating device to automate full DNA sample preparation processes for gram-positive bacteria.
We have developed a miniaturized bead-beating device to automate nucleic acids extraction from Gram-positive bacteria for molecular diagnostics. The microfluidic device was fabricated by sandwiching a monolithic flexible polydimethylsiloxane (PDMS) membrane between two glass wafers (i.e., glass-PDMS-glass), which acted as an actuator for bead collision via its pneumatic vibration without additi...
متن کاملModification of extraction method for community DNA isolation from salt affected compact wasteland soil samples
To overcome the issue of interferences by salt and compactness in release of bacterial cell required for lysis, method described by Yeates et al. (1998), was optimized for isolation of genomic material (Deoxyribo Nucleic Acid, DNA) from soil microbial community by addition of Al(NH4)SO4. Very low total viable count was observed in the samples tested and hence use of higher amount of soil is req...
متن کاملBack to Basics – The Influence of DNA Extraction and Primer Choice on Phylogenetic Analysis of Activated Sludge Communities
DNA extraction and primer choice have a large effect on the observed community structure in all microbial amplicon sequencing analyses. Although the biases are well known, no comprehensive analysis has been conducted in activated sludge communities. In this study we systematically explored the impact of a number of parameters on the observed microbial community: bead beating intensity, primer c...
