![]() The findings suggest that bifunctional characteristics of AHE68 was metabolically stable for extended period of time (up to 30 days) to improve microalgal productivity. In co-culture studies, AHE68 was found to be metabolically capable to simultaneously synthesise active forms of IAA and organic acids under salt-stress conditions. The endophyte AHE68 was found to significantly enhance 22.71% and 79.27% increase in microalgal cell numbers and lipid contents in co-culture systems, respectively. GA001 were characterised in different combinations of synthetic co-culture systems. Interactions of AHE68 and long-chain fatty acids (LCFA) producing microalga Micractinium sp. ![]() AHE68, a phosphate solubiliser, originally isolated from endangered medicinal plant Aconitum heterophyllum, simultaneously secretes organic acid (10.42 mM mL −1) to convert the inorganic phosphate into organic phosphate as well as produces high level IAA under stress conditions. AHE68 that simultaneously converts inorganic phosphate into organic phosphate (29.8% increase in available phosphorus content) and synthesis growth-promoting IAA (45.34☐.82 μg mL −1) thereby enhances microalgal productivity in synthetic co-culture system. Here, we demonstrate bifunctional characteristics of a Himalayan bacterial endophyte Pantoea sp. ![]() Due to lack of accessibility to endangered medicinal plants of high-altitude Himalayan Mountains, the biotechnological potential of microorganisms associated with these plants has not been largely explored.
