Effect of Soil Physico-Chemical Properties and Plant Species on Bacterial Diversity in Semi-Arid Parts in Central Sudan. Part III: AL-Gaeli Region, Khartoun North
Bacterial diversity and total viable counts of bacteria of the different soil samples from three different localities in AL-Gaeli region, Khartoum North: Kunger, Gary and WadiAb-Gadad sub-regions were carried out. Soil physical and chemical characteristics (pH, EC, SP, soluble cations: Na, K, Ca, Mg and anion P, organic carbon, total nitrogen and soil texture) in each studied sub-regions were measured. Qualitative analysis of microorganisms isolated from the studied soil samples reveal a total of eight different species of bacteria, of which two are unidentified. The six species are classified under Bacillus genera. In study region soil samples, total bacterial counts ranged from 8.5 × 105 cfu·g﹣1 to 1 × 104. The quantitative data on microbial population recorded in the present study was analysed using two diversity indices. Actinomyces spp. and Streptomyces spp. were the most abundant microorganisms identified in the three sub-regions. There were obvious differences in correlation coefficients among the selected criteria that 65% from the total number of correlation coefficients were positively correlated between bacterial counts and soil physico-chemical properties. The development of molecular techniques of microbial identification, coupled with traditional methods is promising areas for continued research.
