In recent years, there has been a phenomenal increase in the use of alkaline proteases as industrial catalysts. The aim of this work was to isolate potent fungal strain from the agricultural field of Gulbarga region of India, for the production of alkaline protease by utilizing the agricultural by products viz, red and green gram and Bengal gram as substrate under submerged fermentation process. Optimization of fermentation process parameters such as substrate (Red gram husk, green gram husk and Bengal gram husk) utilization, utilization, temperature, pH and incubation period for alkaline protease production was carried out. The maximum production of alkaline protease by Trichoderma VPG 12 was found at pH 8, temperature 35 °C, incubated for 120 h. But the activity of the enzyme could also be seen in a wide range of pH (5-9) and temperature (20-40 °C). With all these properties, the strain can be considered for industrial grade production of alkaline protease.

The present study was carried out to investigate the thrombolytic and antimitotic potentiality of various extracts of fruits of Ficus glomerata, a traditional medicinal plant, using an in vitro assay method. Three crude extracts such as petroleum ether (FGPE), chloroform (FGCE), and methanol (FGME) were used for the study, with a standard (streptokinase) and negative control (sterile distilled water) to validate the method. The thrombolytic nature of the plant was found significant with methanol extract and chloroform and petroleum ether extracts have recorded mild activity, when compared with the negative control (sterile distilled water). The extracts have shown mild clot lysis, that is, 2.16%, 23.06%, 27.60%, and 47.74% of sterile distilled water, FGPE, FGCE, and FGME, respectively, while the standard (streptokinase) has shown 74.22% clot lysis. FGME inhibited the root growth in number as well as length effectively, followed by FGPE, while FGCE exhibited moderate antimitotic activity and it was supported by mitotic index. Therefore, the obtained results suggest that among all the extracts of plant the methanolic extract has shown highest thrombolytic and antimitotic activity.
