Bacterial communities of the rhizosphere soil of Mangifera indica

Rhizosphere, soil, Bacterial communities, Mangifera indicaAbstract
Rhizosphere soil plays an important role in providing environment conducive for growth of plants, therefore the knowledge about its living constituents is of paramount importance. The present study has partially determined the dynamics of bacterial communities in the rhizosphere soil of Mangifera indica, an indigenous fruit tree. Soil samples from the rhizosphere of Mangifera indica were collected from various locations and analysed for bacterial load and communities. The experiments were performed in two distinct phases under two different growth conditions such are aerobic and anaerobic. The data of aerobic phase of this study revealed presence of spore forming and non-spore forming aerobic bacterial species belonging to Bacillus, Enterobacter, Pseudomonas, Proteus, and Serratia genera, while the findings of anaerobic phase yielded members of genus Lactobacilli only. Lactobacilli occupied an average 17% of total anaerobic communities of bacteria in the rhizosphere of Mangifera indica, while aerobic bacilli occupied only 8.33% of total aerobic bacterial communities. Data indicated that the rhizosphere soil of Mangifera indica is rich in bacterial communities belonging to both aerobic and anaerobic groups. However, the load of bacterial isolates
varied dramatically from sample to sample suggesting that in addition to type of plant other factors such as soil environment and nutrients may influence the bacterial communities in the rhizosphere soil of a plant.
