In Vivo effect of Antibiotics on the occurance of Azotobacter chroococcum in the rhizoshere of tomato
Keywords:
Azotobacter, Rhizobium, Sewage farming, streptomycin, amoxicillinAbstract
The increasing agricultural reuse of treated effluent serves goals such as promoting sustainable agriculture preserving scarce water resources and maintaining environmental quality. Also, irrigating with wastewater may reduce purification levels and fertilization costs, because soil and crops serve as bio-filters and wastewater contains nutrients. Influence of sewage and sewage components such as soaps, antibiotics, spices, oils and fats, toothpastes, household pesticides, heavy metals etc. on the growth of Azotobacter chroococcum in vitro and in rhizosphere and soil was evaluated. Sewage farming is still continued in many towns if the irrigation facilities are not available. Sewage irrigation supported the population of nitrogen fixers such as Azotobacter, Rhizobium and also fungal organisms used for organic matter decomposition. In the present study A. Chroococcum was isolated from the rhizosphere and soil from sewage irrigated fields and the effect of antibiotics such as streptomycin and amoxicillin on nitrogen fixation in tomato inoculated with A. Chroococcum was seen. antibiotics reduced streptomycin and amoxicillin A. Chroococcum population in the rhizosphere and in soil as well.
