Bio-based anti-fouling for membranes & marine surfaces.

Synthetic biology company that has developed a peptide to prevent bio-film formation, one of the most prevalent issues in industry, at extreme levels of potency, for desalination, cooling towers & maritime.

Key thesis

Biofilm forms everywhere. Biofilm formation is one of the oldest and most expensive operational problems in industry - driving energy loss, downtime, corrosion, and biofouling. Traditional methods for removing biofilm are mechanical cleaning and chemical cleaning, both of which are expensive, and the latter of which is damaging to the environment.

DisperseBio has synthetically replicated a natural protein found on sea anemones that signals bacteria to disperse, rather than killing bacteria. The beauty of this innovation is its potency - it has an extremely high level of scalability, requiring less than a few hundred grams of the peptide to clean some of the largest desalination plants in South Asia, at a fraction of the cost.

Overview

Disperse Bio is a synthetic biology company, which has developed a bio-mimicry based peptide that prevents bio-fouling (the build-up of biological matter on surfaces). The company leverages over 15 years of academic and applied research, supported by several patents. Preventing bio-film formation is applicable widely across industries. DisperseBio is targeting desalination, shipping, oil & gas, cooling towers, and semiconductors as initial markets, given the scope and cost of the problem.

At the core of DisperseBio's innovation is a bio-mimicry based peptide that causes biofilm-forming microbes to disperse before biofilms form, which avoids triggering microbial resistance, works at ultra-low (ppb/nanomolar) concentrations, and is non-toxic to humans and the environment.

Benefits
  • Easy integration: compatible with existing dosing systems
  • Ultra low dosage: effective at ppb concentrations
  • Reduced chemical footprint: lowers dependence on toxic biocides
