Question:
An article in Journal of Applied Microbiology ["Use of Response Surface Methodology to Optimize Protease Synthesis by a Novel Strain of Bacillus sp. Isolated from Portuguese Sheep Wool" (2012, Vol. 113(1), pp. 36-43)] described a fractional factorial design with three center points to study six factors (yeast extract, peptone, inoculum concentration, agitation, temperature, and pH) for protease activity. Response units were proteolytic activity per ml (U/ml). The data follow.
