Cassava Leaf Extract as an Acid-Base Indicator

This research was conducted to test the feasibility of cassava (Manihot esculenta) leaf extracts as acid-base indicator. There is a growing need to utilize indigenous resources as materials in the laboratory. The results of this study can be a basis for use of cassava, a locally available plant in the country, as an important aid in chemistry.

MPDX: An HTML Encryptor-Decryptor

Transferring data from one location to another is conveniently made possible by the Internet. However, the Internet’s overwhelming capabilities are accompanied by a questionable computer security. This study was conducted to address this problem by means of developing software that can protect transferred files over the Internet.

Harnessing the Antibacterial and Nutritional Potential of Kudit

Since kudit (Schizophyllum commune Fr.) is regarded as a wild edible mushroom, its nutriceutical and antibacterial properties were evaluated. S. commune contains an appreciable amount of protein at 22 percent, crude fiber (3.59 percent), and carbohydrates (59.56 percent) which merit it to be considered as nutritious food. The immobilized form of S. commune could overcome and suppress the growth and further colonization of Staphylococcus aureus and Escherichia coli.

Propagation and Utilization of Philippine Wild Stinkhorns

This project was conducted to determine the edibility and to harness the economic potentials of Philippine stinkhorns. This study makes use of three stinkhorns, namely, Dictyophora, Mutinus, and Clathrus. Mycelial biomass of these three stinkhorns was produced using different indigenous culture media. Cytotoxicity test was done to determine the biosafety of these stinkhorns using shrimp nauplii.

The results showed that the three stinkhorns exhibited antibacterial activity against E. coli with Dictyophora having the greatest antibacterial activity. It also showed that the best medium for Clathrus and Dictyophora was the potato sucrose broth while for the Mutinus was the rice bran decoction. The cytotoxicity test showed that all these three stinkhorns were not toxic to human cells.
