There was an another government department named The Central Testing laboratory (CTL) which was established in Dhaka in 1956 to provide testing facilities to government‚ private industries‚ Organizations and business community. In 1985 Bangladesh Standards & Testing Institution comes into being through an Ordinance (Ordinance XXXVII of 1985) with the merger of Bangladesh Standards Institution and the Central Testing Laboratories. In this report‚ we tried to highlight the salient features of

had a cloudy overall appearance and the growth appeared to be even throughout the specimen. There was minimal growth in the 7% NaCl solution and most of that growth was adhering to the sidewall of the tube. No growth was observed in the 15% NaCl solution. The results of the S. epidermidis specimens were very similar to those of S. cerevisiae. In the 1% NaCl solution a large amount of growth was noted. This specimen was not as cloudy as that of the S. cerevisiae but growth was consistent throughout

). Callie Vee’s Grandfathers’ Laboratory The Laboratory is really just a shed that used to be part of old slave quarters. Instead of a door there is an old tan burlap flap. Scattered around the laboratory there are various beakers filled with peculiar smelling liquids (from Callie’s grandfathers “experiments” on how to distill pecans into whiskey) in assorted colors. There is a large ruined armchair with stuffing oozing out of it. Further into the laboratory there is a library‚ a dim room with
