Area of Science:

  • Biotechnology
  • Enzymology

Background:

  • Lipase enzymes are vital in various industries.
  • Culture media composition significantly impacts industrial lipase production costs.
  • Optimizing media is key to cost-effective enzyme manufacturing.

Purpose of the Study:

  • To maximize lipase production from Bacillus sp. ZR-5.
  • To identify optimal culture media components for enhanced enzyme yield.
  • To reduce industrial lipase production costs through media optimization.

Main Methods:

  • Employed a "one variable at a time" optimization strategy.
  • Evaluated low and high-cost carbon and nitrogen sources.
  • Assessed various substrates and incubation times.

Main Results:

  • Maximum lipase activity was achieved at 24 hours incubation.
  • Optimal low-cost carbon source: 1.5% glucose syrup (1600±69.1 u/mg).
  • Optimal low-cost nitrogen source: 1% fish powder (1238±36.7 u/mg).
  • Optimal substrate: Olive oil (1407±2.1 u/mg).

Conclusions:

  • Low-cost sources significantly increase lipase activity.
  • This optimization can substantially reduce media costs for industrial lipase production.
  • The findings support cost-effective industrial enzyme applications.
