[Tomicide adsorption on bacterial cells]

Area of Science:

• Microbiology
• Biochemistry

Background:

• Bacteriocin-like factors exhibit antimicrobial properties.
• Understanding their interaction with microbial cells is crucial for applications.

Purpose of the Study:

• To investigate the adsorption capacity of tomicid's bacteriocin-like factor onto microbial cells.
• To determine factors influencing this adsorption process.

Main Methods:

• Studied adsorption under varying conditions: microbial sensitivity, tomicid concentration, contact time, temperature, and pH.
• Quantified nonspecific sorption of the bacteriocin-like factor.

Main Results:

• Tomicid's bacteriocin-like factor nonspecifically adsorbs to microbial cells (64-128 units/mg dried cell mass).
• Low temperatures (0°C) and specific pH ranges (4.8, 5.4) inhibited binding.
• Lysozyme-like substances in tomicid affected adsorption on sensitive cells.

Conclusions:

• Adsorption is influenced by multiple factors including environmental conditions and microbial properties.
• Tomicid's bacteriocin-like factor exhibits complex interactions with microbial surfaces.
