Effect of amino acids on the production of cyclosporin a byTolypocladium inflatum
Cyclosporin A was produced in semi-synthetic and synthetic media byTolypocladium inflatum in suspension culture. L-valine increased the specific production of cyclosporin A by 62% in semi-synthetic media and by 4...

Dynamics of l-valine in relation to the production of cyclosporin A by Tolypocladium inflatum
We report the kinetics of endogenous l-valine in the fungus Tolypocladium inflatum, in an effort to understand the enhancing effect of externally supplemented l-valine on the production of the immunosuppressant c...

Enhancement of catharanthine production by the addition of paper pulp waste liquors to Catharanthus roseusin chemostat cultivation
Dialyzed paper pulp waste liquor added at 20% (v/v) basal medium improved the production of indole alkaloid, catha-ranthine, from Catharanthine roseus, yielding 51 μ:g/cell as against 42 μg/cell in non-supplem...

Growth-associated synthesis of recombinant human glucagon and human growth hormone in high-cell-density cultures of Escherichia coli
Synthesis of two recombinant proteins (human glucagon and human growth hormone) was investigated in fed-batch cultures at high cell concentrations of recombinant Escherichia coli. The glucose-limited growth was a...

Synthesis of mini-proinsulin precursors using N-termini of human TNF α as fusion partners in recombinant Escherichia coli
Synthesis of human mini-proinsulin precursors was investigated in controlled fed-batch cultures at high cell concentrations of recombinant Escherichia coli. Transcription of the recombinant gene was controlled by...

Improved process for production of recombinant yeast-derived monomeric human G-CSF
The human granulocyte colony-stimulating factor (hG-CSF) was efficiently secreted at high levels in fed-batch cultures of recombinant Saccharomyces cerevisiae. However, the secreted recombinant hG-CSF (rhG-CSF) ...

Enhanced expression of tandem multimers of the antimicrobial peptide buforin II in Escherichia coli by the DEAD-box protein and trxB mutant
The tandem multimeric expression of various peptides has been explored by many researchers. However, expression levels have usually not been proportional to the degree of multimerization. To increase the expr...

Xylanase production in solid state fermentation by Aspergillus niger mutant using statistical experimental designs
The initial moisture content, cultivation time, inoculum size and concentration of basal medium were optimized in solid state fermentation (SSF) for the production of xylanase by an Aspergillus niger mutant usin...

Monitoring the denitrification of wastewater containing high concentrations of nitrate with methanol in a sulfur-packed reactor
Biological denitrification of high nitrate-containing wastewater was examined in a sulfur-packed column using a smaller amount of methanol than required stoichiometrically for heterotrophic denitrification. I...

Reductive effect of H2 uptake and poly-β-hydroxybutyrate formation on nitrogenase-mediated H2 accumulation of Rhodobacter sphaeroides according to light intensity
Nitrogenase-mediated H2 accumulation of Rhodobacter sphaeroides under photoheterotrophic conditions is reduced directly by the hydrogenase activity catalyzing H2 uptake and indirectly by energy-demanding metabol...

Degradation of an endocrine disrupting chemical, DEHP [di-(2-ethylhexyl)-phthalate], by Fusarium oxysporum f. sp. pisi cutinase
The efficiency of two lypolytic enzymes (fungal cutinase, yeast esterase) in the degradation of di-(2-ethylhexyl)-phthalate (DEHP) was investigated. The DEHP-degradation rate of fungal cutinase was surprising...

Enrichment of microbial community generating electricity using a fuel-cell-type electrochemical cell
A fuel cell was used to enrich a microbial consortium generating electricity, using organic wastewater as the fuel. Within 30 days of enrichment the maximum current of 0.2 mA was generated with a resistance o...

N-halamine biocidal coatings
Novel N-halamine siloxane and epoxide coatings are described. The coatings can be rendered biocidal by exposure to dilute bleach. Once the bound chlorine is lost from the coatings, it can be regenerated by furthe...
