marcescens growth and prodigiosin production. S. marcescens is the organism worked with in this lab. Temperature, salinity, oxygen requirements, carbon source, and pH were the conditions tested. The characteristics that were studied using the five conditions were the growth of S. marcescens in relation to prodigiosin production over a period of three hours. Senaite Tewolde-Mesfin Professor Eaton BIO 101-Lab 24 October 2014 Abstract: In this experiment, S. marcescens was the organism we worked
activity of the enzyme with 1X enzyme concentration was a little higher than 1⁄2X but they were not significantly different. However, the enzyme activity with 2X enzyme concentration was twice the activity at 1X. There was no enzyme activity at a pH of 1 while pH 7 showed significant activity.
BIOFUELS Two problems roused the world’s concern in recent years. One is energy crisis caused by the squandering of petroleum fuel. Second problem is environmental problems such as greenhouse effect, global warming, etc. To deal with such problems, renewable sources, utilization technology and bioenergy production technology have been developed. Bioethanol as one of the biofuel can be blended in different proportions in automobiles with gasoline. Biobutanol is also a new biofuel (Liu, Wang, & Zhang
