“…Bacterial endophytes have been recognized as repository of novel secondary metabolites for potential therapeutic use (Tan and Zou 2001). Further, Strobel and Daisy (2003) necessitated that medicinal and endemic plants should use for endophytic studies as they are expected to harbor rare and interesting endophytes with novel bioactive metabolites.…”

The diversity and beneficial characteristics of endophytic microorganisms have been studied in Plectranthus tenuiflorus medicinal plant. However, information regarding naturally occurring P. tenuiflorus plant associated endophytes among different organs of host is limited. Endophytic bacteria were isolated from root, stem, and leaves of P. tenuiflorus plant. Among 28 endophytic bacterial isolates from different organs of P. tenuiflorus plant, 8 isolates were identified by partial sequencing of their 16S rRNA gene. The isolated endophytic bacteria were Bacillus sp., Bacillus megaterium, Bacillus pumilus, Bacillus licheniformis, Micrococcus luteus, Paenibacillus sp., Pseudomonas sp., and Acinetobacter calcoaceticus. The most isolates that exhibited extracellular enzymatic activity were belonged to the genus Bacillus. Furthermore, Bacillus sp. (HE613660) exhibited the stronger activities in extracellular enzymes such as amylase, esterase, lipase, protease, pectinase, xylanase, and cellulase than other strains. Considerable antimicrobial activities against a panel of human pathogenic microorganisms (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Streptococcus agalactiae, Proteus mirabilis, and Candida albicans) were recorded using crude extracts of the collected endophytic strains.

“…It acts as biocontrol agents against the phytopathogens. The endophytes also act as growth hormones to regulate the host growth conditions [3][4] . Microbes are found in plants and plays an important role in producing plant growth hormones, enzymes, and siderophores, and may act against plant diseases and insect pests 5 .…”

The present study was carried out to isolate and identify the endophytic fungi from different plant parts (Leaves, Twig, and Shoot) of Limonia acidissima L. and to screening the antioxidant activity. The plants samples were collected and processed within 24 hours with modified surface sterilization. The plants segments were placed on PDA incubated for four weeks. The emerging fungal colonies were sub-cultured and identified morphologically and microscopically. The present study proves that the plant segments of endophytic fungi colonized 150 Segments were screened from leaves, twigs and shoot of selected medicinal plant. A total of 34 isolates were obtained. Among them 7 were classified into sterile morphospecies, remaining were classified into 28 species which belongs to 11 genera. The predominant endophytic fungi were Phyllosticta Sp., Phoma Sp., Nigrospora sphaerica, Alternaria alternata, Dreschlera australiensis, Sterile forms. The phytochemicals present in the Limonia acidissima L. were Tannins, Saponins, Terpenoids, Cardiac glycosides, Steroids, Flavonoids and Phenols. The antioxidant of free radical scavenging activity was recorded around 99% inhibition at the concentration of 25mg/ml. The Limonia acidissima L. were 100% of endophytic fungal infection and also the endophytes are effectively free radical scavenging activity and the R square values are significant. The microbes are fast producers for natural products and it makes excellent drugs for curing many diseases.

“…There has been considerable interest in screening the endophyte for bioactive compound (Kumar and Hyde 2004). A large number of compounds (secondary metabolites) have been extracted, isolated and characterized from endophytic microbes (Tan and Zou 2001;Strobel et al 2004). This article reviews the different endophytes associated with the crop plants, their mode of infection in the plants and how plants can be benefited with endophytisms.…”
