(4 units) SPRING QUARTER
Instructor
COURSE GOALS: This laboratory course aims to train students in the laboratory methods used in the microbiological analysis of foods. Upon completion of this course, students are expected to be able to use standard culturing methods for isolating, identifying and enumerating microorganisms in different food and environmental samples, and understand and predict how different food processing methods impact the levels of microorganisms in food.
PREREQUISITES: BIS 2A; BIS 102 and 103; FST 104
COURSE FORMAT: One hour of lecture, two three-hour laboratories, and one hour of discussion are offered each week.
