It is important to know the comprehensive microbial communities of fecal pollution sources and receiving water bodies for microbial source tracking. Pyrosequencing targeting the V1–V3 hypervariable regions of the 16S rRNA gene was used to investigate the characteristics of bacterial and Bacteroidales communities in major fecal sources and river waters.(More)
The base sequences representing human and cow-specific 16S rRNA gene markers identified in the T-RFLP analysis were recovered from clone libraries. The human and cow-specific primers were designed from these sequences and their specificities were analyzed with fecal DNAs from human, cow, and pig. AllBac primer set showed positive results for all human, cow,(More)
Specific fecal DNA markers were investigated for major pollution sources, cow, human, and pig, and occurrence of the identified markers was analyzed in river waters using Terminal Restriction Fragment Length Polymorphism (T-RFLP) techniques and sequencing of 16S rDNA of Bacteroides-Prevotella. The unique and specific DNA markers for cow and human were(More)
E-business web sites were collected and evaluated by different aged subjects to detect the emotional gap between the elderly and non-elderly. Professional web designers, seniors, and young subjects participated in the experiment and seniors’ emotional perceptions of e-business proved to be different from the perception of the non-elderly.
