چکیده

Physiologic activity and community structure of planktonic and biofilm microbial communities in an urban river were analyzed using 5-cyano-2,3-ditolyl tetrazolium chloride (CTC) staining, fluorescent in situ hybridization (FISH) and denaturing gradient gel electrophoresis (DGGE) analysis of polymerase chain reaction (PCR)-amplified 16S rDNA fragments. Respiring bacteria estimated by CTC reduction were higher in biofilms (20%) than in stream water samples (12%). FISH analysis revealed that bacterial populations in both stream water and biofilms were dominated by [beta]-Proteobacteria and Cytophaga-Flavobacterium cluster. Microbial community changes determined by multidimensional scaling analysis from DGGE patterns showed that microbial community structures in biofilms matured within 3-7 days of their formation and did not change further, while those in stream water changed continuously.

Enhancement of PCR amplification yield and specificity using AmpliTaq Gold DNA polymerase.

Inadequate yields of PCR product and the generation of nonspecific PCR products can complicate genotyping studies, particularly when the DNA template is of inferior quality and/or has a low-copy number. In this study, the ability of AmpliTaq Gold DNA Polymerase to enhance the specificity and yield of amplification was evaluated in a quadruplex short tandem repeat (STR) system in which a nonspec...

Comparable sensitivity and specificity of nested PCR and single-stage PCR using a thermally activated DNA polymerase.

To augment sensitivity and specificity of polymerase chain reaction (PCR), a nested PCR protocol is used (1). This procedure allows detection of even single copies of specific template sequences (5,6) but requires additional manipulations (such as opening of reaction tubes and transfer of PCR products), which may increase the risk of contamination and lead to false-positive results. To avoid th...

Advantages of a new Taq DNA polymerase in multiplex PCR and time-release PCR.

Extensive diagnostic and scientific investigations are often restricted by limited availability of material. Therefore, methods like multiplex PCR strategies are needed to conserve as much sample as possible. Unfortunately, the establishment of such procedures poses several difficulties. Here we describe the advantages of a new enzyme, AmpliTaq Gold DNA Polymerase, in multiplex and time-release...

AmpliTaq and AmpliTaq Gold DNA Polymerase

Oligodeoxyribonucleotide primers based on the 5' ends of bovine IgG1/2 and [lambda] constant (C) region genes, together with primers encoding conserved amino acids at the N-terminus of mature variable (V) regions from other species, have been used in cDNA and polymerase chain reactions (PCRs) to amplify heavy and light chain V region cDNA from bovine heterohybridomas. The amino acid sequences o...
