Aluminium is one of the most abundant metals. This metal is responsible for inhibiting growth and productivity of many cultures thereby affecting the metabolism of most of the microbes. The current study is aimed at examining the effect of glucose addition on bacterial growth under aluminium stressed conditions. For this purpose, nutrient broth was supplemented with different concentration of aluminium viz. 0mM, 20mM, 60mM and 80mM. In addition to above heavy metal supplementation, the nutrient broth was additionally provided with varying concentration of glucose (0.25%, 0.5% and 1% glucose). The Bacillus and Burkholderia cultures were allowed to grow in all possible combinations of provided aluminium and glucose concentrations. In case of Bacillus culture, when media was supplemented with 0.5% glucose, the culture growth was increased upto 2.0-folds in 20mM aluminium toxic conditions whereas growth of Burkholderia strain increased upto 5.0-folds and 8.0-folds in case of 20mM and 60mM aluminium stressed conditions respectively. The results conclude that under aluminium toxic conditions, 0.5% glucose supplementations could prove to be beneficial for bacterial optimal growth.
