Embodiment 1
[0124]
[0125] The inclined bacillus culture of Gnomonia cingulata bacterial strain (CBS 15226) was inoculated in a container containing 3% by weight of glucose, 1% by weight of corn steep liquor, 0.2% by weight of NaNO 3 , 0.1 wt% KH 2 PO 4 , 0.2 wt% K 2 HPO 4 , 0.05% by weight KCl, 0.05% by weight MgSO 4 ·7H 2 O and 0.002 wt% FeSO 4 ·7H 2 O (pH 6.0) in 1000 ml of nutrient solution autoclaved at 121° C. for 30 minutes in a 2-liter Erlenmeyer flask at 28° C. on a rotary shaker at 165 rpm for 72 hours. After such preculture, it was inoculated in a 20 liter fermenter covered with 19 liters of sterile medium having the same final composition as the preculture described above. In addition, another 1.0 ml of silicone oil and 1.0 ml of synperonic (oxoalcoholethoxylate) were added to reduce foaming. After a 12-hour growth period at an overpressure of 0.7 bar at a temperature of 28°C, aeration at 20 l / min, stirring at 250 rpm and addition of 4.0 g of 17β-hydroxy-7α-methyle...

[0127]
[0128] The Incline bacillus culture of Glomerella cingulata strain (IFO 6425) was inoculated in a container containing 3% by weight of glucose, 1% by weight of corn steep liquor, 0.2% by weight of NaNO 3 , 0.1 wt% KH 2 PO 4 , 0.2 wt% K 2 HPO 4 , 0.05% by weight KCl, 0.05% by weight MgSO 4 ·7H 2 O and 0.002 wt% FeSO 4 ·7H 2 O (pH 6.0) in 1000 ml of nutrient solution autoclaved at 121° C. for 30 minutes in a 2-liter Erlenmeyer flask at 28° C. on a rotary shaker at 165 rpm for 72 hours. After such preculture, it was inoculated in a 20 liter fermenter covered with 19 liters of sterile medium having the same final composition as the preculture described above. In addition, another 1.0ml of silicone oil and 1.0ml of synperonic were added to reduce foaming. After a 12-hour growth period at an overpressure of 0.7 bar at a temperature of 28°C, aeration at 10 l / min, stirring at 350 rpm and addition of 2.0 g of 17β-hydroxy-7α-methylestr-4-en-3-one 30ml of DMF solutio...
Embodiment 3
[0131]
[0132] The culture of Aspergillus ochraceae (CBS 13252) was inoculated in a culture chamber containing 3% by weight of glucose, 1% by weight of corn steep liquor, 0.2% by weight of NaNO 3 , 0.1 wt% KH 2 PO 4 , 0.2 wt% K 2 HPO 4 , 0.05% by weight KCl, 0.05% by weight MgSO 4 ·7H 2 O and 0.002 wt% FeSO 4 ·7H 2 O (pH 6.0) in 500 ml of nutrient solution autoclaved at 121° C. for 30 minutes in a 2 L Erlenmeyer flask, shaken at 28° C. on a rotary shaker at 165 rpm for 72 hours. After such preculture, it was reinoculated in a 10-liter fermentor covered with 9.5 liters of sterile medium having the same final composition as the preculture described above. In addition, another 0.5ml of silicone oil and 0.5ml of synperonic were added to reduce foaming. After a 6-hour growth period at an overpressure of 0.7 bar and a temperature of 28°C, aeration at 5 liters / min, stirring at 350 rpm and addition of 1.0 g of 7α-methylestr-4-ene-3,17-dione 15ml DMF solution.
