Abstract

The promoting effect of electromagnetic field (EMF) on biosynthesis and activity of extracellular proteinase and lectin in B. subtilis 316 M was observed. It caused 1.5- and 4-fold increase of the metabolites yield respectively. The EMF stimulated a 2-fold activation of lectin, rise of the enzyme activity and a shift of it pI from 11.4-11.5 to 9.2-9.3.

Main findings

Exposure to an electromagnetic field was reported to promote biosynthesis and activity of extracellular proteinase and lectin in Bacillus subtilis 316 M, with 1.5-fold and 4-fold increases in metabolite yield, respectively. The EMF was also reported to activate lectin (~2-fold), increase enzyme activity, and shift enzyme pI from 11.4–11.5 to 9.2–9.3.

Outcomes measured

  • Biosynthesis/yield of extracellular proteinase
  • Biosynthesis/yield of lectin
  • Lectin activity
  • Enzyme activity
  • Isoelectric point (pI) shift of enzyme

Limitations

  • No EMF exposure parameters reported (e.g., frequency, intensity, duration).
  • No sample size or replication details provided in the abstract.
  • In vitro bacterial study; relevance to human health outcomes not addressed.
