Abstract:
More food needs to be produced for the growing human population, but the possibilities of expanding the area of arable land are limited. Cellular Agriculture is an emerging field of biotechnology, aimed at finding alternatives to agricultural production of various commodities. As a part of Cellular Agriculture, the use of microbes and microalgae as food and feed with high protein content, so-called single cell protein (SCP), is gaining renewed scientific and commercial interest. In this review, we give an introduction to SCP production by heterotrophic microbial species, phototrophs, methanotrophs and autotrophic hydrogen oxidizers, as well as highlight some challenges and the latest developments in the growing SCP industry.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
