Background: A glycolipopeptide biosurfactant produced by Pseudomonas aeruginosa strain IKW1 reduced the surface tension of fermentation broth from 71.31 to 24.62 dynes/cm at a critical micelle concentration of 20.80 mg/L. The compound proved suitable for applications in emulsion stabilization in food, as well as in cosmetic and pharmaceutical formulations. Methods: In the present study, Placket...

For those interested in tackling industrial optimization problems, typical approaches include either purchasing a sophisticated and often specialised solver perhaps with accompanying consulting support, using an internet-based optimization server or using a Matlab toolbox. While there are a number of open source optimization solvers that enable one to solve a wide range of continuous and discre...

among pome fruit trees, quince is the most susceptible tree to fire blight. following selection of several promising quince cultivars, this research aimed at optimization of in vitro propagation protocol of the selected materials. therefore, several experiments were carried out for determination of the best culture medium and plant growth regulators for establishment, proliferation and root ind...

Background: The pregnancy rates from oocytes matured in vitro are much lower than those of in vivo stimulation cycles, indicating that optimization of IVM remains a challenge. Reduced developmental competence of oocytes matured in vitro indicates that current culture systems for oocytes maturation do not adequately support nuclear and/or cytoplasmic maturation. Therefore in this study, we evalu...

A moderately halotolerant Streptomyces strain, designated JAJ13 was characterized and a culture medium was statistically optimized to improve its antibacterial activity. Based on the phenotypic and molecular characteristics, strain JAJ13 was identified as a moderately halotolerant Streptomyces sp. JAJ13. Novelty of the strain JAJ13 in production of antibacterial compound was assessed by sequenc...

Streptomyces sp. JAJ06 is a seawater-dependent antibiotic producer, previously isolated and characterised from an Indian coastal solar saltern. This paper reports replacement of seawater with a defined salt formulation in production medium and subsequent statistical media optimization to ensure consistent as well as improved antibiotic production by Streptomyces sp. JAJ06. This strain was obser...

The design of concentric ring arrays for isoflux radiation is presented in this paper. This design considers the reduction of the side lobe level and isoflux radiation requirements for Medium Earth Orbit (MEO) satellites. The optimization problem considers the spacing among rings and levels of amplitude excitations. The well-known method of Particle Swarm Optimization (PSO) is utilized for this...

Present work is devoted to the problem of validity increasing an experiment detect motion a continuous medium by waveguide method. The study attempts optimize find optimal scheme for its installation. target effect, magnitude which should be maximum, generalized reflection coefficient, influenced both Fresnel electromagnetic drag coefficient and polarization plane rotation due medium. main opti...
