“…The major enzymatic antifouling mechanisms include: cell lysis by degradation of components of the cell membrane, degradation of compounds anchoring cells to the surface: (i) of adhesives produced during settlement and anchorage and (ii) of the extracellular matrix secreted by proliferating adhered organisms (Oulahal 2007, Van Houdt andMichelis 2005), disruption of intercellular communication: quorum sensing, i.e., bacterial cell-cell communication (Kristensen 2008) and degradation of environmental substances (i) that are fundamental for the survival of the fouling organisms or (ii) generating antifouling compounds (Cordeiro 2011). …”

The use of enzymes has a high potential in the pulp and paper industry to improve the economics of the paper production process and to achieve, at the same time, a reduced environmental impact. Specific enzymes contribute to reduce the amount of chemicals and energy required for the modification of fibers and helps to prevent the formation or development of biofilms. This review is aimed at presenting the latest progresses made in the application of enzymes as refining aids and biofilm control agents.

“…This phenomenon, known as biofouling, has severe negative impacts in industry and in medicine, for example by clogging membranes and filters, or causing infections. The use of enzymes to control biofouling has been receiving increasing attention (Olsen et al 2007;Kaplan 2009;Kristensen et al 2008;Cordeiro and Werner in press 2011). Enzymes are currently available at affordable prices and are therefore viable for industrial use, and since they are biodegradable, they are also environmentally friendly.…”

Immobilized enzymes affect biofilm formation

The effect of the activity of immobilized enzymes on the initial attachment of pathogenic bacteria commonly associated with nosocomial infections (Pseudomonas aeruginosa and Staphylococcus epidermidis) was investigated. The proteolytic enzymes, subtilisin A and the glycoside hydrolase cellulose, were covalently attached onto poly(ethylene-alt-maleic) anhydride copolymer films. A comparison between active and heatinactivated surfaces showed that while the activity of immobilized cellulase reduced the attachment of S. epidermidis by 67%, it had no effect on the attachment of P. aeruginosa. Immobilized subtilisin A had opposite effects: the active enzyme had no effect on the attachment of S. epidermidis but reduced the attachment of P. aeruginosa by 44%. The results suggest that different biomolecules are involved in the initial steps of attachment of different bacteria, and that the development of broad-spectrum antifouling enzymatic coatings will need to involve the co-immobilization of enzymes.

“…These compounds may be non-toxic or toxic, but they can be much less stable than conventional biocides, what should prevent the problem of bioaccumulation of harmful chemicals. Finally, the intercellular communication during colonization of a surface may be hindered by specific enzymes (Kristensen et al 2008). …”

Microbiological control programmes at industrial level should aim at reducing both the detrimental effects of micro-organisms on the process and the environmental impact associated to the use of biocides as microbiological control products. To achieve this target, new efficient and environmentally friendly products are required. In this paper, seventeen non-specific, commercial enzymatic mixtures were tested to assess their efficacy for biofilm prevention and control at laboratory and pilot plant scale. Pectin methylesterase, an enzyme found in the formulation of two of the mixtures tested, was identified as an active compound able to reduce biofilm formation by 71% compared to control tests.
