Polycyclic aromatic hydrocarbon (PAH) pollutants originating from oil spills and wood and fuel combustion are pollutants which are among the major threats to mangrove ecosystems. In this study, the composition and relative abundance in the sediment bacterial communities of naphthalene dioxygenase (ndo) genes which are important for bacterial adaptation to environmental PAH contamination were in...
Soil microorganisms play an important role in agricultural ecosystem. However, there is little information about the effects of putative allelochemicals on specific soil vivo. Cucumber seedlings were treated with four concentrations ferulic and p-hydroxybenzoic acids (0-1.0 μmol g-1 soil) soil. Effects rhizosphere Fusarium community structures abundance analyzed by polymerase chain reaction den...
ganisms increases, which provides a means to determine phylogenetic relationships and to distinguish microorSeparation of polymerase chain reaction (PCR)–amplified 16S ganisms from one another (Woese, 1987; Woese, 1992). rDNA products using denaturing gradient gel electrophoresis (DGGE) was tested as a means to study microbial community compoPresently, the rRNA genes in DNA taken directly from ...
