    Abstract Background: This study targets the enhanced production of L-asparaginase, an antitumor enzyme by Acinetobacter baumannii ZAS1. This organism is an endophyte isolated from the medicinal plant Annona muricata. Plackett-Burman design (PBD) and central composite design (CCD) were used for statistical optimization of media components.
    Results: The organism exhibited 18.85 ± 0.2 U/mL enzyme activities in unoptimized media. Eight variables: L-asparagine, peptone, glucose, lactose, yeast extract, NaCl, MgSO
    Conclusion: The findings of this study indicated that an endophyte, Acinetobacter baumannii ZAS1 that produces L-asparaginase could be used to increase enzyme output. However, using the statistical methods Plackett-Burman design and central composite design of response surface methodology is a handy tool for optimizing media components for increased L-asparaginase synthesis.

    Abstract Morel mushrooms, Morchella species are highly nutritional, excellently edible and medicinal. Anticancer activity of M. elata, growing in forests of Kashmir Himalaya was studied. Ethyl acetate extract of fruiting bodies of M. elata (MEAE) was evaluated for cytotoxicity by MTT assay using Daltons lymphoma ascites (DLA), human colon cancer (HCT-116) and normal cell lines. Anti-carcinogenic and antiangiogenic activities of MEAE were tested using mouse models. Proapoptotic activity was detected by double staining of acridine orange-ethidium bromide assay. MEAE was partially purified by column chromatography and the bioactive compounds were identified by LC-MS analysis. The bioactive extract of M. elata showed significant cytotoxicic activity against DLA (P < 0.05), HCT-116 cell lines (P < 0.05) and did not possess appreciable adverse effect on the viability of normal cells. At a concentration of 100 µg/mL, 60% cell death was observed in HCT-116 cell line while 80% cell death was found in DLA cell line. The extract also possessed profound anticarcinogenic, antiangiogenic and proapoptotic activities. LC-MS analysis showed celastrol (RT 9.504, C29H38O4, MW 450.27), convallatoxin (RT 9.60, C29H42O10, MW 550.27), cucurbitacin A (RT 11.97, C32H46O9, MW 574.71) and madecassic acid (RT 14.35, C30H48O6, MW 504.70) as the major bioactive components. Current experimental studies indicated that bioactive extract of M. elata possessed significant anticancer activity. Being an excellently edible mushroom, the potential therapeutic use of M. elata and its bioactive extract in complementary therapy of cancer is envisaged.
