Purpose of the Study:

• To investigate the inhibitory effects of guaiacyl and syringyl compounds on microbial growth.
• To identify specific compounds with potent antimicrobial activity.
• To assess the potential of lignin-derived compounds as antimicrobial agents.

Main Methods:

• Testing inhibitory effects on model cultures of bacteria, yeasts, yeast-like microorganisms, and moulds.
• Evaluating compounds with guaiacyl and syringyl structures.
• Comparing the efficacy of different compounds against microbial growth.

Main Results:

• Compounds with guaiacyl and syringyl structures exhibited inhibitory effects on microbial growth.
• Isoeugenol showed the most pronounced inhibitory effect among the tested compounds.
• The study identified isoeugenol as a potent inhibitor of bacterial, yeast, and mould growth.

Conclusions:
