“…In fact, various studies have indicated that the plant species have an influence on the structure and composition of the microbial communities (Duineveld et al, 2001;Kuske et al, 2002;McCulley and Burke, 2004;Orlando et al, 2007). Likewise, in the absence of plant cover the microbial community presents a structure different from that of the community associated with plants in both sampling times.…”

“…Currently, there is a lack of information on the microbiology of these semi-arid soils from the matorral. A previous study using T-RFLP analysis demonstrated that there are differences between the structures of the bacterial community from soil associated with C. hystrix compared to bulk soil (Orlando et al, 2007). The approach based on the T-RFLP analysis of 16S rRNA genes to assess the spatial or temporal heterogeneity of microbial communities at the field scale has been used in different environments (Marsh,1999;Dunbar et al, 2000;Sá nchez et al, 2004;Morales et al, 2006;Hartmann and Widmer, 2006;Hullar et al, 2006).…”

“…This study is focused on the soil bacterial communities associated with a vegetational fragment from the Chilean sclerophyllous matorral. Previous work showed that the soil bacterial community associated with C. hystrix was different to bacterial assemblages from the neighboring interspace soil (Orlando et al, 2007). However, it is unknown if the structure and composition of the microbiota associated with this actinorhizal plant differs from that associated with the non-actinorhizal plant species found in the same area, and which the edaphic factors could explain these differences.…”

“…These root exudates create unique environments for the microorganisms living in the rhizosphere. There are differences in utilization of different compositions of root exudates by the microorganisms, and thus, different rhizosphere communities were formed (Rumberger et al, 2004;Orlando et al, 2007).…”

To understand the mechanism of soil microbial ecosystem and biochemical properties in suppressing soilborne plant diseases, the relationship between the soil rhizosphere microbial communities, hydrolase activities, and different disease-resistant cultivars was investigated. There were statistically significant differences in microbial diversity in the rhizosphere soil between the disease-tolerant cultivar Fj01 and susceptible cultivar Baxi. The rhizosphere soil of Fj01 showed a trend of higher microbial diversity than that of Baxi. At the same growth stage, the similar trends of variation in microbial community diversity between the two different cultivars were observed. The bacterial community abundance in rhizosphere soil from the two banana cultivars was quantified by real-time PCR assays. The size of the rhizosphere bacterial population from the Fj01 was significantly larger than that from the Baxi during the growing stage from July to September. The activities of urease and phosphatase were analyzed to study the effects of the two banana cultivars to soil ecosystem functioning. Urease activity was significantly higher in the rhizosphere soil of Fj01 than that of Baxi in the period from July to September. However, phosphatase activity showed no significant difference between the two different rhizosphere soils.

“…Microbial communities can provide useful data to study both applied and basic environmental events (Govaerts et al 2007). To better understand the role of microbial communities in the processes occurring in the soil and how they respond to environmental changes, it is essential to determine the structure and function of these microbial assemblages (Orlando et al 2007).…”

Soil bacterial functional diversity as influenced by cadmium, phenanthrene and degrade bacteria application

There are increasing concerns over compound pollution in northeast of China and its bioremediation. Cd, Phe, degradation bacteria W.J and their combination on soil microbial community function were assessed with the BIOLOG method. The microbial community was extracted from the soil with different treatments. Average color development, richness, Shannon-Weaver index, and principal component analysis on OD standardized data were performed. The results showed that soil microbial metabolic diversity in CK was significantly higher than that in the soils in which Cd, Phe, W.J or their combination was added. It indicated that Cd, Phe has significantly negative effect on the sole-carbon-source metabolic ability of soil microbial communities, particularly when both of them were present. Application of degradation bacteria incubation makes soil microbial communities same as control except for the significant decrease in 4-hydroxy benzoic acid, L-serine, glucose-1-phosphate metabolism. It shows that the incubate application has a considerably effect in soil communities reversion.
