Isolation and identification
The endophytic fungal diversity in medicinal plant Centella asiatica was studied to evaluate
the production of bioactive compounds. The plant was taxonomically identified and authenticated
by Botanical Survey of India, Tamilnadu Agricultural University, Coimbatore. The voucher
specimen was deposited there with register number BSI/SRC/5/23/2011-12/Tech.-932. In addition
to the morphological characterization, molecular methods were carried out to confirm the
identification of most promising endophytic fungal strain CA-01 isolated from the C. asiatica (L).
Conidiophores erect, usually unbranched, septate, at the apex with a verticil of erect primary
branches, each with a verticil of secondary and sometimes tertiary branch lets or with a vertical of
conidia- bearing cells borne directly on the slightly inflated apex of the conidiophores, sometimes
with secondary conidiophores borne on the apex of the main conidiophores. Conidia borne in
chains which typically form a brush-like head. Conidia globose, ovate, or elliptical, smooth or
rough. It was identified as Penicillium sp. The fungal sequence was submitted in National Centre
for Biotechnology Information with accession number HM068965 with the name Penicillium sp.
