Exam (elaborations) BIO 25OL LAB 4 SELECTIVE MEDIA AND AGAR, BIO 25OL LAB 4 SELECTIVE MEDIA AND AGAR, QUESTIONS AND ANSWERS. 2023 UPDATED VERSION. 1. What is the difference between chemically defined and chemically complex media? Give either a clinical or environmental research example for which each media type would be the most appropriate choice for culturing microorganisms. The distinction between chemically defined and chemically complicated media is based on their chemical composition. Arrangements All known compositions, such as glucosebroth, are chemically defined media. While chemically complicated media, such as nutritional broth, is unknown and can change from batch to batch 2. Why is differential media typically inoculated with isolated colonies that have been previously cultured on general growth media? Because it facilitates the growth of select bacteria, differential media is often inoculated with isolated colonies that have previously been cultivated on general growth media. Biochemical reactions from distinct species or groups can be visibly distinguished fromthese organisms.
