6. Ideonella Sakaiensis: Recently, scientists have been exploring the use of microbes (bacteria and fungi) to break down plastics, offering an eco-friendly solution to combat plastic pollution. One such microbe is Ideonella sakaiensis, which has the unique ability to degrade polyethylene terephthalate (PET), a widely used plastic.

• About Ideonella sakaiensis: Taxonomy: Genus: Ideonella
• Family: Comamonadaceae / Sphaerotilaceae
• Discovery: Identified by Japanese researchers Kohei Oda and Kenji Miyamoto (Kyoto Institute of Technology & Keio University).

• Characteristics: Gram-negative, rod-shaped, and motile.
• Non-sporing, non-pigmented, monotrichous bacterium.
• Advantages: Can completely degrade PET into harmless building blocks.
• These breakdown products serve as food for sakaiensis and other organisms.
• ·Other Plastic-Degrading Microbes & Organisms
• Microbes for Natural Polymers: Cellulose → degraded by cellulolytic microbes.
  • Chitin (fungi, insects) → degraded by chitin-degrading microbes.
  • Cutin (leaf surfaces) → degraded by cutinases.
