Hello students today will be studying chapter microbes in human welfare in that we’ll be studying topic bacterial bio fertilizer we all have seen how biofertilizers have helped humankind one example of bio fertilizer is earthworm but do we all know there are biofertilizers available except that of birth erathworm yes anabaena nor stock cyanobacteria all this a bio fertilizer which are microorganisms so let us study about them today. Today we’ll be studying how bacterial biofuels have helped mankind and what are those bacterial by fertilizers anabaena not stock rhizobia this our bacterial bifertilozer is a it means they are bacteria now when I talk about anabaena rhizobia they live with leguminous plants they live in symbiotic association with leguminous plants what is symbiotic association lagunas lands like peas beans pulses they require a lot of nitrogen to grow now they cannot take all of this nitrogen directly so what they do is inside the root nodules inside the soil where this plants grow their lives a bacteria called rhizobia this lives where bacteria catches the nitrogen from the atmosphere and from the ground and give it to the leguminous plants and in return this leguminous plants keep the Rhizobium bacteria food and shelter so these two groups or the plants or the bacteria help out each other this is a give-and-take relationship and this give-and-take relationship is nothing but symbiotic Association basically all leguminous plants which require nitrogen live in symbiotic association with one or another nitrogen fixing bacteria anabaena try Sophia as a cofactor these are all nitrogen fixing bacteria there is a term called slag hemoglobin like hemoglobin means this bacteria resides inside the root nodules of the leguminous plants when you cut leguminous plants you can see the bacteria right so we are present inside there in bunch let us understand how bacterial biofuel is helped once [Applause] biofertilizers an example of this is try Sophia as a coab actor Xanthomonas these are bacterial bio for Eliza’s they are nitrogen fixing bacteria it means they help to fix nitrogen in leguminous plants they live in symbiotic association with roots of leguminous plants example it could be B or people or any of the done that is to remove Marty since leguminous plants require nitrogen when the group and that is approximately 80% nitrogen bacterial by fertilizers they provide clients with nitrogen and in return they get food and shelter from plants in the process of providing nitrogen they help the plant to grow better this is basically given a kind of relationship both of them are benefited from each other whenever you go repulses rhizobia or as a cofactor is present inside salt which held the plant to grow better and absorb nitrogen I hope you all have understood what bacterial bio for lenses are and what is symbiotic association or give-and-take relationship thank you
