Sorbitol Can Be Produced Not Only Chemically But Also Biotechnologically
Autor: Rainer Jonas, Mauricio Moura da Silveira
Publikováno v: Applied Biochemistry and Biotechnology. 118:321-336
Sorbitol, a polyol found in many fruits, is attracting increasing industrial interest as a sweetener, humectant, texturizer, and softener. It is principally produced by chemical means. The bacterium Zymomonas mobilis is able to produce sorbitol toget

Previously grown cells of the ethanologenic bacterium Zymomonas mobilis produce sorbitol and gluconic acid, in reactions catalysed by the periplasmic enzymes glucose-fructose oxidoreductase (GFOR) and glucono-delta-lactonase (GL). The GFOR/GL system

Screening for microorganisms that produce only endo-inulinase
Autor: Sandra Aparecida Furlan, Rainer Jonas, Jorge Luiz Ninow, Regina Maria Miranda Gern
Publikováno v: Applied Microbiology and Biotechnology. 55:632-635
Sixteen fungal strains reported in the literature as endo-inulinase producers and three bacterial strains, isolated from the dahlia rhizosphere, were analysed for endo-inulinase production. From four isolated strains (one fungus and three bacteria) t

Optimization of pH, Temperature and Inoculum Ratio for the Production ofβ-D-Galactosidase byKluyveromyces marxianus Using a Lactose-free Medium
Autor: Maria de Fátima Carvalho-Jonas, Andrea Schneider, Sandra Aparecida Furlan, Roselene Merkle, Rainer Jonas
Publikováno v: Acta Biotechnologica. 21:57-64
The pH, temperature and inoculum ratio for the production of β-galactosidase by Kluyveromyces marxianus CDB 002 were optimized using sugar-cane molasses (100 g/l) in a lactose-free medium. The temperature optimum was evaluated in the range from 28

The optimal initial volumetric oxygen transfer coefficient (KLa) was 60 h−1 for the production of β-d-galactosidase from Kluyveromyces marxianus CDB 002, using sugar cane molasses as carbon source. At this KLa applying an agitation/aeration relati

A lactose-free, low-cost culture medium for the production of β-d-galactosidase by Kluyveromyces marxianus was formulated. At high aeration rates (2.2 vvm) and concentrations of 100 g sugar cane molasses l−1 as carbon source and 100 g corn steep l

Publikováno v: Applied Microbiology and Biotechnology. 49:732-736
Propionibacterium shermanii CDB 10014 is able to grow even at high oxygen transfer rates (24.0 mmol O2 l−1 h−1), in contrast to reports in the specialised literature, where all Propionibacteria are considered oxygen-sensitive microorganisms. Prop
