#11 Feasibility of Callus Induction Using a Makeshift Hood for the Micropropagation of Yakal (Shorea astylosa) Jhunel Arian S. Arroyo, Stephanie G. Lanuza, Janella Mae R. Salamania ABSTRACT Today, Shorea astylosa, a species endemic to the Philippines is now critically endangered due to logging and kaingin. This project aimed to successfully establish a technique for micropropagating Shorea astylosa through the process of callus induction using a makeshift hood. For the micropropagation of Shorea astylosa, shoot explants were first immersed in a disinfecting solution containing 20% (v/v) commercial bleach (Zonrox) and 0.05% (v/v) Tween-20 or teepol detergent, incubated and then rinsed. They were then cultured to induce calluses on a Murashige and Skoog medium supplemented with antibacterial and antifungal mixtures and the following concentration ratios of Indole-3-acetic Acid (IAA) to 6-benzylaminopurine (6-BA) (µM): 20 to 0; 15 to 5; 10 to 10; 5 to 15; 0 to 20; and 0 to 0. Four days after placing the explants in the culture media, contaminations were found in the form of bacterial and fungal colonies. The ineffective disinfecting technique for the Shorea astylosa explants may be accounted for these contaminations because the aseptic techniques used (e.g. flaming the mouths of the bottles) as well as the makeshift hood proved to be effective when no contaminations were found four days after the culture medium was prepared for each setup. It is recommended that more research be done for other more effective disinfecting methods for the said explants. #12 Effectivity of a Wastewater Filter composed of Moringa oleifera seeds, Citrus aurantium fibers and Nata de Coco Emmanuel Kenneth F. Artillera, Jasper S. Baliong, David Robin M. Mañalac ABSTRACT Wastewater contains undesirable and even dangerous substances, and is capable of polluting an already limited water supply. Although commercially available wastewater filters are capable of handling this problem, an alternative filter is needed, due to the high cost and inaccessibility of current filters for poor communities. This project tested the combination of malunggay (Moringa oleifera), nata de coco and dalandan (Citrus aurantium) peels as a potent wastewater filter that can simultaneously filter out metal ions and bacteria. For this experiment, a filter setup with the three components was prepared. Its effectivity was tested using a 1L copper sulfate solution for filtration of metal ions and a test tube of Escherichia coli, diluted to 50mL, for filtration of bacteria.
Bacterial colony counts were done before and after filtration. The bacterial concentrations had three replicates and were measured using the colony counting method. The colony counts of each replicate before the filtration process were compared with the colony counts taken after the filtration process. The copper concentrations in both the filtered and unfiltered water were set to be measured using an Atomic Adsorption Spectrophotometer (AAS). However, the particle size of the filtered water samples exceeded the maximum size the AAS can tolerate. Thus, the results for the copper concentration for both filtered and unfiltered samples were not obtained. In conclusion, the wastewater filter was capable of filtering out significant amounts of E. coli. It is recommended that the setup of wastewater filter be modified so as to apply positive pressure during filtration. #13 Effectivity of Methyl Sulfonyl Methane (MSM) from Capsicum annuum (Chili pepper) Extracts as hair Growth Enhancer Alexis John R. Avilla, Aerold Louise M. Firmeza, Adrian M. Tolentino ABSTRACT Many hair products claiming to increase hair growth are often times expensive or untested, and, therefore, unsafe or ineffective. The study aims to determine the effectivity of MSM from Chili peppers on increasing the rate of hair growth compared to other available hair loss treatments. Six set-ups were used, three for each gender: chili pepper set-up, Aloe Vera set-up (positive control), and control (none applied) set-up. Approximately 1cm x 1cm of the test subject’s (Mus musculus) posterior region was plucked on which the extracts were applied for 9 days. Measurements were obtained by measuring the lengths of hair samples every three days. Results showed a significant difference among all treatments by using single variance ANOVA with a significance level of 0.05. T-test for two independent variables showed that the chili pepper set-up had a significantly greater result than both the control set-up and the Aloe Vera set-up. The project could provide a better alternative to hair loss treatments available in the market. It’s low-cost and easy production can also gain high appreciation from manufacturers in the hair care products industry.
