Researchers Call for Stronger Biosafety Rules for GE Microalgae Biofuels

Experts from Delhi Skill and Entrepreneurship University are calling for stronger biosafety regulations and clearer policies to support the safe development of fourth-generation biofuels produced from genetically engineered (GE) microalgae. In a review, they examined the technological advances, environmental considerations, and regulatory challenges surrounding the commercial use of GE microalgae.

The review highlights that GE microalgae can produce more biofuel by improving light-use efficiency, productivity, and lipid content. However, large-scale cultivation raises concerns about the accidental release of modified microalgae, possible gene transfer, and the safe disposal of processing waste. Although open-pond cultivation remains the most economical production method, the researchers noted that environmental risks and regulatory uncertainty continue to limit commercial adoption.

The authors found that field studies have reported no confirmed cases of gene transfer or consistent adverse environmental effects when proper containment and regulatory measures are in place. They concluded that improved governance is essential to unlock the potential of this sustainable biofuel technology. They recommend comprehensive biosafety assessments, science-based regulations, and effective risk management strategies to ensure safe and sustainable use of GE microalgae for future biofuel production.
