Endophytic Microorganisms that Redise on the Tissues of Living Plants

Two cultures from Kunipipi endogenous Penicillium sp (Curcuma zedoaria (Berg) Roscoe) were isolated. Endogenous bacteria were grown on 5 L of Potatos Dextose Broth (PDB) medium for 3 weeks at room temperature (without shaking). The culture was then extracted with ethyl acetate. The extract was separated and purified by silica gel column chromatography (CC) to obtain two pure compounds as yellow oil (compound 1) and yellow crystal (compound 2).

Endogenous bacteria are microorganisms (bacteria, fungi, actinomycetes) present in robust plant tissues through symbiotic relationships. They are ubiquitous in almost all plants studied to date. Some common endogenous bacteria are Enterobacter sp. It belongs to. Colletotrichum sp. Phomopsis sp. Phylosticta sp. Cladosporium sp. Those endophytic bacteria. Endogenous populations are greatly affected by climatic conditions and the location of the host plant. They produce various compounds which can be used for plant growth, protection of environmental conditions and sustainability, and promotion of a good living environment within the host. They protect plants from herbivores by producing certain compounds that prevent animals from further grazing on the same plant and sometimes as a biological control agent. Many biologically active compounds produced by them are useful not only for plants, but also for humans, which is economically important.

Endogenous bacteria are bacterial or fungal microorganisms which colonize healthy plant tissues between cells and / or between cells without causing serious disease symptoms. They are ubiquitous, have settled in all plants and have been isolated from almost all plants examined to date. Their association can be mandatory or facultative and does not harm the host plants. They show complex interactions with hosts including symbiosis and conflict. Plants strictly limit the growth of endophyte. End fight gradually uses many mechanisms to adapt to its habitat. To maintain stable symbiosis, endophytes produce several compounds that promote plant growth and help them to acclimate more to the environment.
