“…The process of isolation of endophytes from surfacedisinfected plant samples, with cultivation on an appropriate culture medium, has been employed by other authors [18][19][20][21][22]. The high isolation frequencies of endophytic fungi from E. azurea (87.86%) and E. crassipes (88.85%) are similar to the results reported [22] where 90% of leaf samples from tropical rubber trees were colonized by en dophytes.…”

Surface Sterilization of the plant material:The method most frequently utilized to detect and quantify endophytes involves isolation from surface-sterilized host plant tissues. Endophytic isolation was carried out under aseptic conditions. Different symptomless parts of the selected medicinal plants such as stem cuttings, leaves, and roots were used for the isolation of endophytes.The collected medicinal plant samples should be healthy and cleaned thoroughly in gentle running tap water AbstractMycoendophytes are microorganisms that reside internal tissues of living plants without causing any immediate overt negative effects, have been found in every plant species examined to date and recognized as the potential sources of novel natural products for exploitation in medicine, and agriculture with more bioactive natural products isolated from the microorganisms. In the past two decades, many valuable bioactive compounds with antimicrobial, insecticidal, cytotoxic, and anticancer activities have been successfully discovered from mycoendophytes. In the present investigation, endophytic fungi were screened form from stem, twig and leaves of Bixa orellanaL. collected form Sathyamangalam reserve forest. Predominant endophytic fungi isolated from the medicinal plantare Phyllosticta sp., Pestalotiopsis sp., and Phomopsis sp. Statistical analysis of Shannon Diversity Index, Jaccard Similarity Coefficient, and Endophytic Infection Rate were performed to understand the nature of mycophytes in the selected medicinal plant. This is the first report on endophytic fungi documented from this medicinal plant from Sathyamangalam forest of Tamil nadu, India.Keywords: Mycoendopytes; Jaccard similarity coefficient; Endophytic infection rate; Shannon diversity index

“…Apparently, this is second report for the isolation of Staphylococcus sp as endophytic bacteria (Stamford et al, 1998). The research with endophytic microorganisms is more focused in species with economic value such as corn, soy, grasses and others (Petrini, 1984;McInroy and Kloepper, 1995;Halmann et al, 1997;Naffaa et al, 1998;Araújo et al, 2000;Costa et al, 2001) or species capable of producing antimicrobials, as Taxus wallachiana (Yang et al, 1994). The method of the radial diffusion in solid media indicated the activity in qualitative form, directly correlating the diameters of the halo of degradation and the colony (Enzymatic Index) (Lin et al, 1991).…”

The objectives of this work was to isolate endophytic bacteria from Jacaranda decurrens Cham. and screening of some enzymes of biotechnological interest. Ten (10) bacterial species were isolated and identified from the leaves and steams. All the isolates presented enzymatic activity, which was ranked as follows: proteolytic (60%) and amilolytic activity (60%), lipolytic (40%), esterasic (40%). However, cellulolytic and pectinolytic activities were not detected. This is the first report on the isolation and identification of endophytic bacteria from Jacaranda decurrensCham.

“…Azevedo J.L. et al, 2000;Araújo, et al, 2000). On the other hand, given the high genetic diversity in group II, it was possible that more than one species of Guignardia similar to G. mangiferae was endophytic in these plants.…”
