Abstract:
Three-stage multiflow cultivation of the yeast Pichia pinus, with the flow rates of 0.27, 0.6 and 1.2 hr-1, respectively, in the first, second and third fermenters, resulted in autoselection and the parent strain was substituted by a selective one in the third fermenter. The selective strain differed from the parent one by the size of cells, had a higher specific growth rate, and contained more protein. These properties of the selective strain were preserved in the course of one-stage cultivation.

Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...

Continuous fermentation is a key strategy in industrial ethanol production, particularly when efficiency, scalability, and high yields are essential. This approach allows for uninterrupted operation and optimized resource utilization. The primary feedstock, corn starch, undergoes enzymatic hydrolysis facilitated by α-amylase and glucoamylase. These enzymes break down the starch into fermentable sugars such as glucose, which are readily assimilated by fermentative microorganisms.Fermentation...
