Progress in Bacillus subtilis Spore Surface Display Technology towards Environment, Vaccine Development, and...

Area of Science:

• Biotechnology
• Microbiology
• Protein Engineering

Background:

• Spore surface display is a highly promising technology due to its cost-effectiveness, efficiency, and enhanced protein display capabilities.
• Spores exhibit remarkable tolerance to harsh conditions (heat, pH, chemicals), making them ideal for industrial applications where other microorganisms fail.
• Bacillus subtilis is a preferred host for spore display, being Generally Recognized As Safe (GRAS) by the WHO, unlike easily ruptured yeast and bacteria.

Purpose of the Study:

• To review the applications of spore surface display in environmental, medical, and industrial sectors.
• To highlight the advantages of spore display over traditional cell surface display methods.
• To discuss strategies for optimizing protein expression and activity using different vectors and display systems.

Main Methods:

• Review of existing literature on spore surface display technologies.
• Analysis of the properties of various spore-forming bacteria, particularly Bacillus subtilis.
• Examination of different vectors, coat proteins, and linker selection strategies for enhanced display.

Main Results:

• Spore surface display provides enhanced protein expression and high enzymatic activity compared to other methods.
• Spores offer superior stability and reusability in demanding industrial processes.
• Bacillus subtilis spores are a safe and effective platform for displaying various proteins.

Conclusions:

• Spore surface display is a versatile and advantageous technology for environmental, medical, and industrial applications.
• Optimizing display systems through vector and linker selection can further enhance protein expression and functionality.
• The GRAS status of Bacillus subtilis solidifies its role as a leading microorganism for robust surface display systems.
