Is there a difference in the cfu/ml counts for the two treatment conditions

Heating kills most of the bacteria in the solution. Only some bacteria will survive whose temperature optima is higher, or are heat resistant.

Formula for calculating CFU/ml = no. of colonies * dilution factor / volume plated (in ml)

Suppose the number of colonies in normal solution plate comes out to be 300 and that in the heated solution plate comes to be 30, then cfu/ml for heated solution = 30*10^0/ 0.1 = 300 cfu/ml; and cfu/ml for normal solution = 3000cfu/ml

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
