Answer: P. chrysogenum produces significantly higher yields of penicillin.
- A P. chrysogenum produces a noticeably different type of penicillin compound entirely
- B P. chrysogenum produces significantly higher yields of penicillin
- C P. chrysogenum is considerably easier to identify under standard laboratory conditions
- D P. notatum was found to be mildly toxic to humans under certain conditions
Correct answer: B. P. chrysogenum produces significantly higher yields of penicillin
Explanation: Penicillium chrysogenum produces penicillin in much higher yields than Penicillium notatum (where it was originally discovered), making it more economically viable for large-scale industrial production.
Sewage passes through physical removal (primary), then aerobic biological treatment where microbes form flocs that consume organic matter (secondary); the settled activated sludge is then digested anaerobically to produce biogas - a deliberate switch from aerobic to anaerobic conditions between stages.
