Evaluation of phosphate Solubilization by root endophytic aquatic Hyphomycete Tetracladium setigerum

The endophytic aquatic fungus Tetracladium setigerum Grove (Ingold) isolated from healthy roots of Berberris vulgaris growing in a riparian area was screened for its phosphate solubilization potential. This was estimated by a solubilization index (SI) using Pikovskaya’s (PVK) agar medium. Solubilized phosphate was quantified with the help of PVK broth medium. The Solubilization index of T. setigerum was ranged from 1.33 to 1.50 during the seven days of incubation and the highest soluble P (3.51 mg/L) was recorded in PVK broth after 21 days of incubation. The present study indicates that the studied root endophytic aquatic fungus may be a promising source of bio-fertilizer.
