A synthetic biologist engineers bacteria to produce a drug at 3.5 mg per liter per hour. If a bioreactor runs for 36 hours with continuous production in a 2,000-liter tank, how many grams of the drug are produced?

**How Synthetic Biology Is Revolutionizing Drug Production—and How Big Bioreactors Drive It Forward** In the backstage of modern medicine, a quiet revolution is unfolding: bacteria are being reprogrammed like digital code to manufacture life-saving drugs with remarkable precision. At 3.5 milligrams of active compound produced per liter per hour, engineered microbes can deliver steady output over days—no small feat in today’s demand for efficient, scalable pharmaceuticals. When anchored in a 2,000-liter bioreactor running continuously for 36 hours, this process yields not just numbers, but tangible progress. So, how does this biological machinery work, and what does it truly produce? For those curious about advanced drug manufacturing, synthetic biologists are cutting-edge developers who reprogram microbial systems to act as living factories. These engineered bacteria convert glucose or feeding media into therapeutic compounds through carefully optimized metabolic pathways. Operating at 3.5 mg per liter per hour means each liter delivers nearly half a gram of drug every hour—rapid and reliable, even at scale. Over 36 hours inside a 2,000-liter tank, the volume expands dramatically: a full bioreactor runs contain 7,200 liters of culture. Multiply total production rate—3.5 mg/L/hr by 7,200 liters and 36 hours—and the result exceeds 910,000 milligrams. Converting to grams reveals a rich yield of about 910 grams. This figure reflects the raw, measurable output of continuous microbial synthesis, transforming lab innovation into real-world medicine.
