African Transnational Diasporas strain reaches its maximum of protease synthesis after 48 hrs of submerged fermentation. The process of fermentation and enzyme recovery is described. The protease shows a pH-optimum of about 3, is stable between pH 3 and pH 6 at temperatures of 40 °C and has a temperature optimum of 60 °C.作者: 技術(shù) 時間: 2025-3-24 01:59 作者: 寵愛 時間: 2025-3-24 04:57
