Abstract: An endophytic fungus from gingko, that is, Fusarium proliferatum DZHQ1 having antitumor activity and antibacterial activity, is isolated from the ginkgo bark. The species of the strain is determined by the combination of colonial morphology and 18 sRNA sequencing, and then the anti-cervical cancer activity of a crude extract of the strain is detected by MTT. Finally, a secondary metabolite of the strain with an inhibition rate of more than 50% is isolated by semi-preparative HPLC, which promotes the further screening of individual compounds with anti-tumor activity. Moreover, the metabolite of the endophytic fungus from gingko shows a more pronounced inhibition in the detection of activity against E. coli and/or S. aureus, and has potential use in the preparation of new antibacterial products.

Abstract: A metal hydride rechargeable cell is provided that discharges during a test discharge at a rate of 8 C to 18 C and a cell temperature of 0° C. where the voltage remains above 0.2 volts during the half of the discharge curve. The cell comprises a negative electrode of hydrogen storage alloy material having a particle size volume distribution whose d(50) value does not exceed 2(2Dht)½, where Dh is the hydrogen diffusion coefficient for the alloy at 0° C. and t is a time period from about 200 to about 450 seconds. A method of manufacturing the cell of the present invention involves an activation protocol comprising at least one formation cycle, a heat treating step, and a cycling step. This method avoids unnecessary processing of the metal alloy material prior to incorporation into the negative electrode.
