December 6, 2012 - Porous aluminium oxide chips employed for novel single-droplet spray drying and viability method of probiotics

Researchers of Wageningen UR and NIZO Food Research (both NL) use porous aluminium oxide (PAO) chips as substrate for the rehydration of semidried particles and the subsequent live/dead staining of Lactobacillus planatarum.

Spray drying is an interesting alternative for the conservation of probiotics. The disadvantage of this process is, however, the decreased survival of the microorganisms. The descripted methodology is complementary to traditional techniques, as such conventional plating of cells. The scientific article was published as: Novel Method for Enumeration of Viable Lactobacillus plantarum WCFS1 Cells after Single-Droplet Drying, Appl. Environ. Microbiol. November 2012 vol. 78 no. 22 8082-8088.

November 22, 2012 - MicroDish BV and the Royal Tropical Institute file a patent on the automatic detection of bacteria

MicroDish BV and the Royal Tropical Institute worked together on the development of an innovative technology for the cultivation, detection and analysis of bacteria, in particular slow growing bacteria, such as Mycobacteria.

The invention provides a method for the detection of growing bacteria, in particular M. tuberculosis, in a self contained setting. Growth is determined by the rate of change in colony surface area.

This approach allows the automatic detection (bright field or fluorescence microscopy) and analysis of the bacterial culture and hence implies a decreased health risk for lab staff. A second advantage of this method is the considerable shorter diagnostics time from weeks to about one week due to the nature of the technology.

30th July 2012 - MaCuMBA: cultivation/isolation of marine bacteria

Marine microorganisms are thought to harbour a plethora of biotechnological relevant compounds. The cultivation of marine microorganisms is, however, challenging. They are often considered to be “unculturable”. The FP7 project MaCuMBA focuses on the improvement of the isolation rate and the growth efficiency of these organisms by applying innovative methods and procedures.
Within this project, MicroDish BV is involved in the screening and isolation of marine bacteria using the MicroDish Culture Chip. The development of high-throughput culture methods and the identification of culture conditions that enhance growth of slow growing microorganisms are additional goals of MicroDish BV. 

MaCuMBA start: August 1, 2012.


4th July 2012 - MDCC chips used in iGEM competition

Wageningen UR iGEM Team 2011 demonstrates the applicability of the MicroDish MDCC chips for studying the dynamics of gene regulatory networks, intercellular signalling, and the cultivation of nematodes in real-time using E. coli cells.
The team designed and manufactured a bacterial cultivation platform in which the GFP expressing E. coli microcolonies where monitored using fluorescence microscopy.
The developed method represents an advanced cultivation technology accessible to a broad range of users and yet being cost-effective and straightforward. The results of the iGEM work were published as “A multi-platform flow device for microbial (co) cultivation and microscopic analysis”, PLOS one, vol. 7, e36982, 2012.

16th January 2012 - Sawa Project

Het ontwikkelen van sensoren voor het meten van drinkwaterkwaliteit. Daar draait het om in het project SAWA. Eind 2011 hebben de ontwikkelde sensoren verontreinigingen in oppervlaktewater gemeten, en lijken dus toegevoegde waarde te hebben voor de drinkwatersector. Vijftien partijen (Microdish ook) zijn eind 2009 gestart met het ontwikkelen van robuuste en kleine sensoren die online en continu stoffen in hele lage concentraties in het water kunnen meten. De ontwikkelde technieken worden in het speciaal ontwikkelde testcentrum SenTec in Glimmen (Groningen) getest en vergeleken met de conventionele meetmethoden. Bij het SenTec kunnen verschillende kwaliteiten water getest worden. Zo ook het water uit het riviertje de Drentsche Aa.  Waterbedrijf Groningen maakt drinkwater uit dit oppervlaktewater. Het drinkwater wordt intensief gecontroleerd door WLN, centrum voor watertechnologie In de toekomst wellicht met behulp van de sensoren die in het SenTec ontwikkeld zijn. En dat lijkt dus te gaan lukken. Najaar 2011 kwam in een bovenloop van de Drentsche Aa per ongeluk een hoeveelheid mest terecht. Via de reguliere meetmethode was Waterbedrijf Groningen al op de hoogte van het incident en legde de inname van oppervlaktewater tijdelijk stil. Van gevaar voor de volksgezondheid is geen sprake geweest. Ook de sensoren die in SenTec staan en onder andere het water van de Drentsche Aa als testwater gebruiken, namen een verandering in de oppervlaktewaterkwaliteit waar. Dankzij dit incident lijkt een eerste bewijs geleverd te zijn dat de waterkwaliteitsverandering door de sensoren haarscherp is vastgelegd, en tegen lagere kosten dan met de reguliere meetmethode. Een hoopgevend resultaat. Voor meer informatie over het project SAWA: kijk op www.projectsawa.nl. SAWA wordt mede mogelijk gemaakt door het Samenwerkingsverband Noord Nederland, het Ministerie van Economie, Landbouw en Innovatie en de Europese Unie.

Happy New Year

A happy and prosperous 2012 to all our customers and collaborators.

October 27th 2010 - Faculty of 1000 Reviews Microbial Printing Paper

The Faculty of 1000 is an organisation of prestigious scientists who review papers after publication, choosing those academic publications that they believe are within the top 2% "cut" for excellence.

MicroDish BV, in collaboration with Top Institute Food and Nutrition, the MESA+ Institute Twente, and Wageningen University (NL) published on printing massive arrays of microorganism earlier this year. This paper, in the lead microengineering journal Lab on a Chip, demonstrated precise and high-throughput contact printing of bacteria within the MDCC using a modified microscope as the "printing press" and a stamp of thousands of micron-scale pins.

New methods to inoculate microorganisms are critical to miniaturizing and increasing the throughput of microbiology in such processes as screening for pathogens or improved industrial strains. F1000 believed this paper represented a significant technological advance.

Printing Bacteria

View of miniaturized pins that can be used to inoculate the MDCC

Microbiologists are adept at handling bacteria with traditional manual tools such as the velvet pad, the wire loop and the sterile toothpick. However, automation and miniaturization is now required. Therefore, to complement our range of MDCCs, a set of high-throughput, multipin inoculation tools have been created (in collaboration with the Top Institute for Food and Nutrition and MESA+). This is another step towards the fully integrated, automated "Microbiology-Lab-on-a-Chip". This work has been accepted for the flagship journal of the microengineering community; Lab-on-a-Chip.
