Antibacterial nanocomposite polyester (PET) fibres were melt spun by adding nano ZnO loaded Linear Low Density Polyethylene (LLDPE) master batch (MB) to the PET chips. The influence of content of nano ZnO on the antibacterial properties, crystallization behaviour and mechanical properties was studied. It was found that PET composite fibres having 1 % nano ZnO showed the optimum antibacterial ac...

To increase cell concentration and the production of alkaline protease, fed-batch cultures with standard medium (1x) or concentrated medium (2x or 5x) as feed were performed. In a fed-batch culture with standard medium as feed, the biomass concentration reached 9.6 g L–1 and the protease activity obtained was 8500 U mL–1 compared to 3000 U mL–1 obtained by growing Teredinobacter turnirae cells ...

Apple pomace extract (APE) in aerobic variable fed batch culture under standardized fermentation parameters was evaluated for the production of baker’s yeast. The substrate was fed at a flow rate of 0.39 dm h to regulate fermentable sugar concentration between 1-2 % in bioreactor. An average specific growth rate of 0.24 h and cellular yield coefficient of 0.48 g/g sugar was obtained during bake...

the effect of dietary sucrose on dna formation in rat liver and kidney compared with that of starch was studied. male, weanling rats were fed for 6 and 14 days on diets containing 68% 'sucrose or 68% starch, and liver and kidneys were examined for 1ilie amount and rate of formation of dna; and also for content of fat, protein, and moisture. food intake and weight gain were estimated. sucrose fe...

Recombinant Escherichia coli XL1-Blue harboring a high-copy-number plasmid containing the Alcaligenes eutrophus polyhydroxyalkanoate synthesis genes could efficiently synthesize poly(3-hydroxybutyrate) (PHB) in a complex medium containing yeast extract and tryptone but not in a defined medium. One of the reasons for the reduced PHB production in a defined medium was thought to be severe filamen...

Considers the problem of reconstructing a continuous-tone (contone) image from its halftoned version, where the halftoning process is done by error diffusion. The authors present an iterative nonlinear decoding algorithm for halftone-to-contone conversion and show simulation results that compare the performance of the algorithm to that of conventional linear low-pass filtering. They find that t...
