The study aims to determine the effect of aqueous extracts of leaves and fruits of the fig plant Ficus carica after and before ripping period when adding it to YEM media on rhizobia bacteria growth, Rhizobium leguminosarum biovar trifolii ANU 536, Sinorhizobium meliloti, Bradyrhizobium parasponia CP283 and Bradyrhizobium sp. 101/U and their production of Lipopolysaccharides (LPS),as an indirect indication of influence of fig plant remains on the plant that have symbiosis relationship with the studied bacteria when planting these plants abreastly.
The result showed the positive effect for aqueous extract of ripping fruits at concentration of 25 mg/ml on the growth of different bacteria and their production of LPS. The concentrations 25,50 and 100 mg/ ml of the extract after ripping period inhibit growth of bacteria, while the other concentrations varied positively and negatively according to their effect on bacteria growth and their production of LPS.
