Bubble column test fermenter system<\/h2>\n

The Vogelbusch pilot fermentation system is designed to test both feedstocks and micro-organisms for their suitability in submerged fermentation under certain defined conditions.<\/p>\n\n

Concept<\/strong><\/p>\n

The key part of the system is a rack with 6 bubble columns that are made of glass. Each column has a gross volume of 17 liters. To expand the capacity of the system further racks can be added.<\/p>\n

The rack is equipped with all necessary devices for measuring and control of fermentation parameter, such as pH probes, temperature probes, partly pO2 probes, as well as an automatic antifoam system and provisions to compensate evaporation losses.<\/p>\n

To expand the capacity of the system further racks can be added.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n

Application<\/strong><\/p>\n

A special advantage of this cost efficient system is the verification of several parameters in parallel within the same cycle.<\/p>\n

In this way test series can be carried out in a timely manner to optimize processes, for instance by addition of nutrients, trace elements and inhibitors.<\/p>\n

This pilot fermentation is employed by Vogelbusch for test series with Aspergillus niger<\/em> to validate the fermentation parameter for citric acid plant design. The same system is in practical use in the laboratories of industrial citric acid production sites.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n

Measures for use with GMO strains<\/strong><\/p>\n

The pilot fermentation system is designed for cultivation of non pathogenic organisms. Intended use of a GMO strain requires prior clarification and implementation of local regulations to comply with, for instance by placing the system into a containment room.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n","protected":false},"excerpt":{"rendered":"
