Optimization of the Fermentation Process of Actinomycete Strain Hhs.015^T

Table 4

Variances and levels of the optimization of strain Hhs.01 fermentation conditions using Response Surface Methodology.

Variables	Parameter			0	1	2
pH		2.0	4.5	7.0	9.5	12
Medium volume (mL)		30	60	90	120	150
Rotary speed (rev/min)		0	50	100	150	200
Temperature ()		15	20	25	30	35
Inoculation volume (%)		8	11	14	17	20

Note: = coded value of the variable . = (pH 7 )/2.5; = (Medium volume 90)/30; = (Rotary speed 100)/50; = (Temperature – 25)/5; = (Inoculation volume 14)/3.
