This article is an overview of microbial enhanced oil recovery (MEOR) and the potential ofSaccharomycesCerevisiaeto be applied in MEOR. MEOR may have same mechanisms with commercial enhanced oil recovery (EOR) but it used biological approach in improving oil recovery.SaccharomycesCerevisiaeproduced carbon dioxide and ethanol under anaerobic condition. The carbon dioxide and ethanol that produced by this microbe are two from the six main MEOR agents in improving oil recovery. This articles also discussed on previous MEOR pilot projects that were conducted in Argentina, China and Malaysia.

Public Service Announcements (PSAs) are free announcements made to promote programs, activities, community interest and services from government and the non - government sector. As technology develops, many PSAs use animated characters in order to persuade and create high awareness among people. Animation is a simulation of movement created by displaying a series of pictures or frames such as cartoons on television. Research has shown that PSAs is effective in conveying the message. However, the influences of animated PSAs among students about health and safety messages are still unclear. Previous researchers were more interested to investigate the effects of PSAs to children and less research on animated PSAs towards adults. Therefore, the researcher is interested to study whether or not the animation should be utilized as an effective tool to educate the public. A sample of 285 students watched four animated PSAs and four live action PSAs. Two of each represented animated spoke characters and non spoke characters with a goal to evaluate students responses on positive attitudes. A correlation analysis was used to study the relationship between the positive response of animated PSAs and engagement with results that indicated moderate and high correlation. T tests were used to investigate the comparison between the students responses to animated PSAs versus non animated PSAs and animated spoke characters versus animated non spoke characters. The results emphasize that animated PSAs received better responses among students. Students acceptance towards animated PSAs and animated spoke characters received small but significantly better response.
