single_cell proteins?

Answer 1

Both photosynthetic and nonphotosynthetic microorganisms, grown on various carbon and energy sources, are used in fermentation processes for the production of single-cell proteins.^Commercial-scale production has been limited to two algal processes, one bacterial process, and several yeast and fungal processes.^High capital and operating costs and the need for extensive nutritional and toxicological assessments have limited the development and commercialization of new processes.^Any increase in commercial-scale production appears to be limited to those regions of the world where low-cost carbon and energy sources are available and conventional animal feedstuff proteins, such as soybean meal or fish meal, are in short supply

Answer 2

yes, of course.......
