A study of inulinase activity in theClostridium acetobutylicum strain ABKn8
Springer Science and Business Media LLC - - 1986
Oxygen limitation is a pitfall during screening for industrial strains

Physiological behavior ofEscherichia coli cultured in the presence of irradiated starch extract
Springer Science and Business Media LLC - Tập 2 - Trang 121-126 - 1976
The lag phase lengthenings recorded for the proliferation ofEscherichia coli cultured in the presence of starch extracts irradiated with cobalt 60 reflect the bactericidal power of radiolysis products. The toxic effect increases with moisture content and esterification of certain hydroxyl functions of the starch, but does not vary after lipid extraction. Washing the starch before irradiation decre...... hiện toàn bộ
Production of food yeast from starchy substrates
Springer Science and Business Media LLC - Tập 15 - Trang 232-236 - 1982
Fifteen yeast strains were selected for the production of food yeast from starchy substrates. From comparison with the amylolytic yeasts, a strain of Schwanniomyces castellii was selected and its characteristics are described.
Degradation of toxaphene by Bjerkandera sp. strain BOL13 using waste biomass as a cosubstrate
Springer Science and Business Media LLC - Tập 71 - Trang 549-554 - 2006
The white-rot fungus Bjerkandera sp. strain BOL13 was capable of degrading toxaphene when supplied with wood chips, wheat husk or cane molasses as cosubstrates in batch culture experiments. Approximately 85% of toxaphene was removed when wheat husk was the main substrate. The production of lignin peroxidase was only stimulated when wheat husk was present in the liquid medium. Although xylanase was...... hiện toàn bộ
Microbial characterisation of polyhydroxyalkanoates storing populations selected under different operating conditions using a cell-sorting RT-PCR approach
Springer Science and Business Media LLC - Tập 78 - Trang 351-360 - 2008
The identity of polyhydroxyalkanoates (PHA) storing bacteria selected under aerobic dynamic feeding conditions, using propionate as carbon source (reactor P), was determined by applying reverse transcriptase–polymerase chain reaction (RT-PCR) on micromanipulated cells and confirmed by fluorescence in situ hybridisation (FISH). Four genera, Amaricoccus, Azoarcus, Thauera and Paraccoccus were detect...... hiện toàn bộ
Continuous production of somatomedin C with immobilized transformed yeast cells
Springer Science and Business Media LLC - Tập 28 Số 3 - Trang 215-221 - 1988
Yeast cells producing the growth hormone somatomedin C (SMC) were constructed and applied in the immobilized form continuously for a period of over 10 days in a flow-through bioreactor. The construction of the MFα1-SMC fusion vector p336/1 is given as well as the results of the influence of various nutrients effecting hormone production. Immobilization of the transformed yeast cells is described a...... hiện toàn bộ
Duplicated Clostridium thermocellum cellobiohydrolase gene encoding cellulosomal subunits S3 and S5
Springer Science and Business Media LLC - Tập 51 - Trang 852-859 - 1999
The upstream region of the cellobiohydrolase gene cbhA of Clostridium thermocellum F7 was sequenced. It was found that this region contains the previously sequenced gene celK encoding an enzyme closely related to CbhA (cellulosomal subunit S3). The presence of a putative transcription terminator in the 524-bp intergenic region indicates that celK and cbhA are not cotranscribed as an operon. Seque...... hiện toàn bộ
Removal of organic air pollutants from exhaust gases in the trickle-bed bioreactor. Effect of oxygen
Springer Science and Business Media LLC - Tập 45 - Trang 415-419 - 1996
The paper describes some reaction engineering fundamentals of the separation of organic air pollutants (volatile organic compounds) from waste gases using fixed-bacteria monocultures (biocatalysts) in a trickle-bed reactor. In particular the influence of pollutant concentration and oxygen concentration are investigated. The separation efficiency of certain substances such as acetone and isopropan...... hiện toàn bộ
