Thesis title: “The potential plant growth-promoting of Cameroon soil bacteria community and their effect on maize growth”
Since October 2015: PhD student under the supervision of Dr. Silke Ruppel.
My background is in plant biology and plant biotechnology. My Master thesis was focusing on phosphate solubilizing bacteria. The goal was to characterize bacteria from acidic soil according to their phosphate solubilizing ability in vitro on plate and shaking culture and evaluate their effect on different plants growth in pots.
Now at IGZ, since it has been shown that bacteria harbouring many beneficial traits can help plant to growth better, I will extend my work to plant growth-promoting bacteria associated with maize plant grown in Cameroon soil.
Maize is one of the prominent food crops in Cameroon. Although it can be cultivated in all five agroecological zones of Cameroon, its productivity remains low due to the acidity and nutrient deficiency of cultivable soils. Biological approaches for improving crops production are gaining strong status and plant growth-promoting have been reported to be present in high population in the rhizosphere and as endophytes of many crops. But, till now nothing is known about which bacteria are associated with maize grown in different agroecological zones of Cameroon. Moreover, it has been shown that for a maximum exploitation of the plant-bacteria association, effective bacteria must be selected in plant studies that take specific ecological conditions in consideration, e.g. crop management, soil and temperature. Therefore, the aim of my research would be to assess the diversity and the functional plant growth-promoting potential of soil bacteria community from maize fields in Cameroon using the phenotypic and genetic approaches, in order to decide which bacteria or group of bacteria can promote better the growth and yield of maize grown in specific environmental conditions in Cameroon.
