Abstract


Statement of the Problem: Endophytes, which have been found in every plant species, are currently considered to be a wellspring of novel secondary metabolites. In view that some plants generating bioactive natural products have associated endophytes that produce the same natural substances the endophytes has become an interesting alternative for functional substances production in a wide variety of medical, agricultural, and industrial areas. Chelidonium majus L. (greater celandine), is a plant occurring naturally in the Europe, Asia and South America. Although the herb is toxic it produces valuable bioactive substances. The preparations of celandine, ie. tinctures, infusions contains alkaloids which inhibit the growth of fungi, bacteria, viruses, protozoans. It has many therapeutic uses and also anticancer properties. Biosurfactants, which are bioactive compounds well known as remediation agents also have potential for medicine. The presence of these compounds in Ch. majus has not been previously studied. Methodology & Theoretical Orientation: A laboratory scale study on isolation of endophytes from Ch. majus origin from three different localization in Poland has been performed. Ability for biosurfactant production of isolated strains was made in the submerge culture condition, in the presence of hydrophobic and hydrophilic substrates, on the base of emulsifying activity and emulsion index I24 measurement. Findings: 17 endophytic strains (11 bacteria, 6 fungi) was isolated. Four of the tested microorganisms have shown high emulsifying activity (above OD500~0,85) and good emulsion - stabilizing capacity (E24~65 %). Conclusion & Significance: These results strongly suggest that the endophytic microorganisms isolated from Chelidonium majus show good emulsification properties which is crucial for biosurfactants production. This is the first report showing the ability for biosurfactant production by Ch. majus endophytes.
