Area of Science:

  • Agricultural Science
  • Biotechnology
  • Environmental Science

Background:

  • Global population growth to 10 billion by 2050 necessitates a 60% increase in food production.
  • Current agricultural practices face limitations due to resource scarcity and climate change, impacting food security.
  • Innovative solutions are required to enhance food production efficiency and mitigate agriculture's environmental footprint.

Purpose of the Study:

  • To review the potential and limitations of microbial protein (MP) as a sustainable food source.
  • To compare the environmental impacts of four MP sources (hydrogen-oxidizing bacteria, methanotrophs, fungi, microalgae) with conventional proteins.
  • To assess the economic viability and challenges of widespread MP adoption.

Main Methods:

  • Literature review of current research on microbial protein production.
  • Comparative analysis of environmental impacts (energy, land, water, GHG emissions) of MP versus plant, animal, insect, and cultured meat proteins.
  • Evaluation of pricing and market competitiveness of MP sources.

Main Results:

  • Microbial protein (MP) production in bioreactors shows promise for sustainable food and feed.
  • MP sources like hydrogen-oxidizing bacteria, methanotrophs, fungi, and microalgae have lower land requirements and higher fertilizer efficiency than traditional agriculture.
  • Environmental impact assessments indicate potential advantages for MP over conventional protein sources, though energy use can be significant.

Conclusions:

  • Microbial protein represents a viable and sustainable alternative protein source to address future food security challenges.
  • Further research and technological advancements are needed to overcome challenges related to cost-effective production and widespread adoption of MP.
  • Optimized microalgae cultivation, particularly under artificial light, offers consistent, high-quality biomass production independent of weather conditions.
