Understanding How Enzymes Help Keep Clothes Clean

21.05.2008
Scientists from Novozymes and two Swedish research institutions have been honored with The Soap and Detergent Association (SDA) Distinguished Paper Award, recognizing the best 2007 research article that appeared in the Journal of Surfactants and Detergents.

The innovative use of an advanced microscopic technique that visualizes and quantifies how enzymes work in laundry detergents to better clean cotton fibers is at the heart of research honored with the The Soap and Detergent Association (SDA) Distinguished Paper Award.

Sponsored by SDA and the Surfactants and Detergents Division of the American Oil Chemists’ Society (AOCS), the award honors the best technical paper published in 2007 in the Journal of Surfactants and Detergents (10:211-218). The Award was presented during the 99th AOCS Annual Meeting and Expo in Seattle, Washington.

Scientists from Novozymes and two leading Swedish research institutions authored the honored paper, “Imaging the Detergency of Single Cotton Fibers with Confocal Microscopy: the Effect of Surfactants and Lipases.”

The research utilized a specialized biophysical microscopy technique (known as fluorescence confocal laser scanning microscopy) to visualize and quantify the effects of a new commercial lipase (lipid degrading enzyme) in assisting the detergency process of removing fats and oils from cotton fibers.

This work is the fruit of a successful collaboration between Novozymes and the two Swedish institutions, Royal Institute of Technology (KTH) and Institute for Surface Chemistry Institute (YKI), with the primary aim of understanding deeper the dynamics of enzymes in a wash process where they interact with detergent components and the fabric/soil load.

One of the major challenges in modern biotechnology is to generate and select relevant biological diversity (in this case enzyme variants) which create value in the application of a customer. This research helped guide scientists’ understanding of the structure/function biophysical properties of the enzyme and how they can be optimized under conditions of use.

“In this research, we created a model system for a wash process to study how the removal of fats and oils from fabric is influenced by the presence of LipexTM, a novel detergent lipase from Novozymes,” said Novozymes Senior Manager Thomas Callisen, one of the honored researchers. “Our microscopy technique allows us, in real time, to zoom in on what happens at the level of single fibers.

“We observe how an oily soil primarily rolls up – at the oil/fiber interface – and detaches from the surface, whereas a more solid-like fatty soiling is found to leave the fabric via necking of emulsion particles from the fat/liquid interface.”

Callisen added that the experiments showed that the lipase – by converting the lipid soil into more water soluble components – accelerates and increase the degree of removal of fats and oils from the fabric surfaces.

“We find that the beneficial effects of the lipase technology are most pronounced in the case of the tougher-to-remove fatty soils,” said Callisen. “As discussed and concluded in our paper, these results corroborate and add further detail to our understanding of the process of enzymatic detergency by lipases.”

Besides Mr. Callisen (who is based in Bagsvaerd, Denmark), the honored researchers include Andreas Sonesson and Ulla Elofsson of the Institute for Surface Chemistry in Stockholm; and Hjalmar Brismar of the Royal Institute of Technology, Stockholm.

The Soap and Detergent Association (http://www.cleaning101.com), the Home of the U.S. Cleaning Product and Oleochemical Industries®, is the non-profit trade association representing manufacturers of household, industrial, and institutional cleaning products, their ingredients and finished packaging; oleochemical producers; and chemical distributors to the cleaning product industry. SDA members produce more than 90 percent of the cleaning products marketed in the U.S. The SDA is located at 1500 K Street, NW, Suite 300, Washington, DC 20005.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
