Superficial air velocity
Kumar et al.(Kumar, Srivastava et al. 2014) studied the effect of superficial air velocity on lovastatin production from A. terreusPL 10 using wheat bran and wheat straw in a 1200-L packed bed reactor. Results showed a maximum lovastatin production of 1.86 mg/g when the reactor was operated using 0.19 vvm airflow rate (23.37 cm/min superficial air velocity).
