E. Coli was grown in nutrient broth (0.3%beef extract and 0.5%peptone) to an early stationary phase (i.e. 18 h) at 37°C.[5] Anti bacterial activity of the nano-carbon materials prepared were tested by immersing 1mg each of PWACT, TWACT, PWAGNP and TWAGNP in 1000 ml of water spiked with E.coli. The same was taken in a 2000 ml sterile, transparent glass vessel with screw cap and stirred for 30
Mixed Unknown Bacteria Lab Report Biology 2460-002 Jamuna Kadariya November 24, 2014 Unknown number: thirty-four I. Abstract There are many types of bacteria and they produce different enzymes. However, some bacteria can produce same enzymes. In order to identify the particular enzymes produce by each bacteria specific test needs to be done. Among various types of enzyme producing bacteria, gram- negative and gram-positive bacteria are given priority in our experiment. There are four main types
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
