Overview of Biofilm Research Services

Inquiry

A biofilm is a structured community of microorganisms that adheres to surfaces and is embedded within a self-produced extracellular polymeric substance (EPS) matrix. This matrix, composed of polysaccharides, proteins, and extracellular DNA, provides mechanical stability and protection, allowing microbes to survive under hostile conditions. Compared to planktonic cells, biofilm-associated microorganisms exhibit enhanced tolerance to antibiotics, disinfectants, and environmental stress. Biofilms are widely found in natural, clinical, and industrial settings and play a critical role in chronic infections, medical device contamination, and antimicrobial resistance.

CD BioSciences provides comprehensive biofilm research services, integrating microbial strain selection, biofilm formation, advanced characterization, and evaluation of antimicrobial and anti-biofilm efficacy.

Antibiotic Sensitivity Testing Services

Our company offers antibiotic sensitivity testing services to enable clients to quantitatively evaluate the antibacterial potency of compounds, including small molecules, antibiotics, antimicrobial peptides, and natural extracts.

Minimum Inhibitory Concentration (MIC) Assay

The MIC is the lowest concentration of an antimicrobial agent that inhibits visible bacterial growth after incubation. It is typically measured using a broth microdilution or agar dilution method, with results expressed as optical density (OD) values.

Applications

Determining the bacteriostatic activity of drugs
Comparing antibiotic efficacy across multiple strains

Minimum Bactericidal Concentration (MBC) Assay

The MBC represents the lowest concentration of an antimicrobial agent that kills ≥99.9% of the initial bacterial population, as confirmed by colony-counting unit (CFU) counting. It complements MIC by distinguishing bactericidal from bacteriostatic effects.

Applications

Antibiotic screening and efficacy comparison
Assessment of antibiotic efficacy against resistant strains

Antimicrobial Susceptibility Testing Services

Our company provides comprehensive antimicrobial susceptibility testing services to evaluate the effectiveness of compounds against biofilm-associated microorganisms. Our platform supports both inhibition and eradication studies, enabling a complete assessment of anti-biofilm activity.

Frequently Asked Questions About Our Services

What is the difference between MBIC and MBEC?

MBIC measures the ability of a compound to inhibit biofilm formation at an early stage, while MBEC evaluates its ability to eradicate established biofilms. MBEC values are typically higher due to the increased resistance of mature biofilms.

How do I choose the right biofilm assay for my study?

The selection depends on your research goal. MBIC and BPC are suitable for prevention studies, while MBEC and BBC are used to evaluate eradication and bactericidal effects in mature biofilms.

What types of microorganisms can be tested?

We support a wide range of microorganisms, including Gram-positive and Gram-negative bacteria, fungi, and drug-resistant strains. Polymicrobial biofilm models are also available.

Can you customize biofilm models based on my project?

Yes, we offer fully customized biofilm models, including a selection of strains, culture conditions, surfaces, and environmental parameters to match your specific application.

What endpoints are typically measured in biofilm studies?

Common endpoints include biofilm biomass, microbial viability, structural characteristics, and gene expression, depending on the study design.
