Use the following passage to answer 2 consecutive
questions.
A urine specimen was collected in a container and
placed on the central desk for delivery at 10:00 am.
The specimen is not sent to the lab until 5 hours later
(3:00 pm). The sample time was marked by the
central clerk as collected at 4:00 pm. The bacterial
species has a generation time of 30 minutes at room
temperature. There are 100 bacterial cells/ml at the
time of collection (10:00 am). The laboratory will cite
a bacterial infection at more than 1000 bacterial
cells/ml.

- Azotobacter vinelandii is being studied for the production of alginate from sucrose. In a continuous culture at 28°C with ammonia as a nitrogen source, the alginate yield obtained was 4 g/g of oxygen consumed. It is desired to produce alginate at a rate of 5 kg/h. As the viscosity of alginate in water is considerable, the energy related to stirring the broth cannot be neglected, and the fermenter is equipped with a Rushton-type turbine. For satisfactory agitation and aeration speed, the estimated energy requirement is 1.5 kW. Calculate the cooling requirement.arrow_forwardA biotechnology company discovers a bacterium isolated from waste industry that produces protease that can operate at high pH. Such protease is useful in making heavy duty detergent that has high pH catalytic condition. Thus, the company decided to produce the protease at large scale using bioreactors. a) Discuss how this is possible when the bacterium is difficult to grow and produce the protease at low level. Suggest any means to overcome these difficulties. b) Suggest what type of bioreactor and mode of culture that is suitable for the production of protease at large scale.
