Construction of a Lactobacillus Casei Ethanologen


Utah State University researchers have developed a technology that enhances Lactobacillus casei’s ability to produce ethanol. L. casei is a nonpathogenic microorganism used in the production of biofuels and bioplastics. While most biofuel methods struggle with deficiencies in production, this technology for biologically-engineered bacterium has shown many improvements and greater stability in ethanol production.

  • Biofuels
  • Bioplastics
  • Chemical engineering

  • Increased ethanol production in microbe
  • Microbe used is a more stable platform for biofuel production
  • Easier extraction of ethanol because of the simple structure of the microbe

Microbial production of biofuels from lignocellulosic substrates is a component of the United States’ plan to reduce its dependency on fossil fuels. Current microorganisms used for biofuel production suffer from several deficiencies. These deficiencies include: relatively low tolerance to the environmental stresses likely to be encountered in fermentation, complex physiology, poor availability of genetic tools, and limited ability to secrete enzymes. USU has developed a method to genetically modify L. casei bacteria for increased production of ethanol.
