Utilization of chlorella sorokiniana in absorption of carbon dioxide on vehicular exhaust emissions / by Christian Rey N. Jardiolin, Marco Louis M. Santerva, Anton Gerald T. Añes, & Shayne Rizzabel A. Provido.

The research aims to investigate the amount of CO2 content existing in the vehicular exhaust gases, utilizing a local SUV-type vehicle, reduced and absorbed by the Chlorella sorokiniana exposed for a period of different time intervals. A model container was originally designed and constructed by the researchers to aid in the process of containing the vehicular gases inside the transparent container with the Chlorella sorokiniana also contained inside the container. The volume of Chlorella sorokiniano was exactly 3 liters while the amount of CO2 levels aerated in the container with an average of 3,681 ppm. In addition, the container was sealed using a heat-resistant silicone sealant and quick-dry epoxy and a verified CO2 meter was utilized for measuring the CO2 levels. The results show that the average rate of CO2 absorbed by the Chlorella sorokiniana was 76.06 ppm and was monitored every 30 minutes applicable for each trial. A One-Way ANOVA test was utilized to determine whether there exists a significant difference in the amount of CO2 levels after the exposure to Chlorella sorokiniano and a multiple comparison test was used to double check the ANOVA results. The researchers concluded that Chlorella sorokiniana aided in the absorption of CO2 contents in emitted gases from the vehicle exhaust. The researchers recommend using alternative microalgae to compare the efficiency and efficacy in absorbing CO2 levels from vehicles. Additionally, researchers suggest investigating the potentiality of Chlorella sorokiniana in reaction with other gas elements to further analyze its capabilities.
