- Abstract
Endophytic fungi exist in interdependent manner inside the host plant with potential to generate the identical bioactive secondary metabolites for which the host plant is recognized. Therefore, the present study aims to identify secondary metabolites, produced by the endophytic fungi isolated from the roots of Taxus wallichiana. Additionally, biological activities, namely antioxidant and antibacterial activity, are also evaluated. Five endophytic fungi i.e., GBPITWR_F1 (Penicillium sp.), GBPITWR_F1 (P. daleae), GBPITWR_F1 (Penicillium sp.), GBPITWR_F1 (Aspergillus versicolor), and GBPITWR_F1 (Aspergillus sp.), isolated from T. wallichiana roots, were used. Extraction of bioactive metabolites was done by maceration methods in four different solvents- hexane, chloroform, ethyl acetate, and methanol in sequential manner. These crude organic extracts were tested for phytochemicals and antioxidant and antibacterial activity. Results revealed the tendency of endophytic fungi to accumulate various bioactive compounds. Gallic acid was found maximum in GBPITWR_F5 (18.35 ± 2.65 mg/g), quercetin higher in GBPITWR_F1 (15.24 ± 2.28 mg/g); taxol content was present in two of the endophytes i.e., GBPITWR_F1 (0.31 ± 0.00 mg/g) and GBPITWR_F (5 0.68 ± 0.00 mg/g). All the endophytes exhibited production of seven important organic acids i.e., ascorbic acid, citric acid, lactic acid, mallic acid, oxalic acid, pyruvic acid, and succinic acid. Additionally, all the endophytes showed potential antioxidants activity- GBPITWR_F3 with ABTS and GBPITWR_F1 with DPPH with IC50 55.15 ± 3.28 μg/mL and 65.12 ± 4.29 μg/mL in ethyl acetate extracts, respectively. Moreover, all the endophytes showed antibacterial activity against Bacillus subtilis, B. megaterium, Escherichia coli, Serratia marcescens, Pseudomonas chlororaphis, and P. palleroniana. GC-MS analysis revealed the presence of phenols, fatty acids, aromatic dicarboxylic acid, and alkaloids in ethyl acetate extracts. The biotechnological, pharmaceutical, and agricultural industries may benefit from these endophytic fungi investigated for the production of a range of secondary metabolites and the antibiotic activity.
