Starch is a versatile product. In addition to being a major source of carbohydrates in people’s diets it has well over 700 non-food derived applications, such as in bulking agents, paper and adhesive.
Many biological and industrial processes, such as mammal digestion, plant metabolism and biofuel production, rely on the hydrolysis of native starch by amylolytic enzymes. These enzymes, represented mostly by α-amylases, break down the starch macromolecules to small carbohydrates and finally simple glucose molecules.
The Cereal Quality Group of CSIRO Agriculture and Food, based in Canberra, together with INRA Unité de Recherches Biopolymères, Interactions et Assemblages in Nantes, have developed a strong common interest in studying the impact of α-amylase in cereal quality and food production.
One such research interest is the beneficial effects α-amylase on bread quality and malting. It is thought that the addition of α-amylase results in the production of fermentable sugar, via starch hydrolysis, thereby fuelling fermentation. In baking, it contributes to shorter fermentation and increases loaf volume.
At the laboratory scale, it has been shown that starch digestion is governed by (1) the type of enzyme digesting the starch. (Each enzyme has a proper mode of action depending on the specific substrate) and (2) the structure and morphology of the starch granule. However, the influence of starch structure on amylolysis in industrial processes remains unclear.
In collaboration with Synchrotron SOLEIL (Paris), researchers have used the unique high-resolution UV imaging setup of the DISCO beamline to localize at high resolution, α-amylase action on starch without staining or use of a fluorescent probe. Like a precise amylase GPS, this has enabled researchers to follow, live and in 3D, the mode of action of a-amylase and the associated morphological changes of starch granules at different stages of their hydrolysis.
As part of the CSIRO/INRA linkage, researchers are now developing a model using a large wheat populations that will predict the degradability of wheat starches by industry grade baking improver α-amylases. This model would make possible to predict starch degradability by commercial α-amylases based on genetic information or structural analysis. It would also provide valuable information on new ways to tailor starch for industrial purposes, for both baking and malting as well as green chemistry and biofuel production.

IMPACT7 is a new event to be held on 1 August at Melbourne’s Meat Market.
The organisers, SlatteryIT, are looking for research innovators to present their projects to industry and public. Their focus is on projects that are solving wicked problems and producing research with impact in one of IMPACT7’s 7 Challenges.
Each successful applicant will receive important feedback and guidance, the chance to win a host of valuable prizes, and opportunities to network with leaders across Australian industry, research, and government.
Please encourage your most innovative researchers to take a look at www.impact7.com.au/apply
Thirty #womeninscience are being offered support and training to become superstars of STEM and role models for the next generation.
Superstars of STEM will smash society’s gender assumptions about scientists and increase the public visibility of women in STEM.
Science and Technology Australia (STA) are looking for 30 of the nation’s most dynamic scientists and technologists to create role models for young women and girls.
They’ll receive training in advanced communication skills and have opportunities to use them – in the media, on the stage, and in speaking with decision-makers.
Applications close on 23 May and full information is available on the STA website.
The PIEPS scheme is open to all publicly funded researchers and involves access to phenotyping capabilities at the Australian Plant Phenomics Facility (APPF) at a reduced cost to facilitate exceptional research projects. This is an outstanding opportunity to gain access to invaluable expertise and cutting edge technology to accelerate your research project and make a real impact in plant science discovery.
Emphasis is placed on novel collaborations that bring together scientists preferably from different disciplines (e.g. plant physiology, computer science, engineering, biometry, quantitative genetics, molecular biology, chemistry, physics) and from different organisations, within Australia or internationally, to focus on problems in plant science.
Applications close: 30 September 2017

On 12 May 2017, the Australian Government has released a comprehensive roadmap outlining the research infrastructure priorities essential for building Australian research excellence into the future. The full document is available here.
It makes 9 key recommendations, including the implementation of a coordinated approach to international engagement and the adoption of nine focus areas:
• Digital Data and eResearch Platforms
• Platforms for Humanities, Arts and Social Science
• Advanced Fabrication and Manufacturing
• Advanced Physics and Astronomy
• Earth and Environmental Systems
• Complex Biology
• Therapeutic Development.
