Current research focuses on the utilization of low value agro‐industrial byproducts for targeting B. subtilis towards different exoenyzeme lines. This includes α‐amylase, β‐mannanase, xylanase, and lichenase. As an orientation step, growth and α‐amylase activity were monitored in three different...
Two enzymes, amylase and protease of Streptomyces species were purified by a combination of ion exchange chromatography and gel filtration and characterized. The amylase had an exoaction on starch yielding maltose as a major end product and was identified as β‐amylase. The purified amylase had a...
L‐form strains of Proteus mirabilis and Escherichia coli lacking the cell wall represent an alternative prokaryotic cell system for the production of recombinant proteins (KLESSEN et al. 1988, LAPLACE et al. 1988 a, 1989b). We could demonstrate that they are also able to synthesize the enzyme...
The ability of Azotomonas to reduce atmospheric nitrogen has been an issue of controversy since this genus was included in the family Azotobacteraceae. Here we report the investigations on the nitrogen fixation characteristics of Azotomonas fluorescens strain ATCC13544 and show that it can grow...
Alcaligenes eutrophus JMP 134 was chemostatically grown on 2,4‐dichlorophenoxyacetic acid (2,4‐D) at a dilution rate of 0.06 h−1; formate was fed as an auxiliary energy source. The simultaneous utilization of both components resulted in an increase in growth yield. As an example, this figure...
The intracellular distribution of glutamine synthetase (GS) in cell‐free extracts of Nostoc muscorum has been investigated. 64–73% of the enzyme activity was associated with the thylakoid membranes. No enzyme activity was found in cytoplasmic membranes. 92% inhibition of the enzyme activity was...
