An optimal control approach is proposed for semi-batch processes based on parameterized data-driven (PDD) model structures. Orthonormally parameterized input trajectories, initial states and process parameters are inputs to the model, which predicts output trajectories in terms of Fourier coefficients. Two model structures (linear and quadratic) are incorporated into PDD modeling approach, and ...

one of the major obstacles of bt production as a biopesticide is its expensive bioprocess and fermentation. therefore, the objective of the present study was to optimize growth condition and develop a low-cost bioprocess for mass production of a native coleopteran-effective bacillus thuringiensis (bt) strain (kh4) based on agricultural wastes, at incubator and batch fermenter level. preliminary...

Renewable energy production using microorganisms is one of the challenging issues for environmental sustainability. Algal hydrogen (H 2 ) has often been achieved by sulfur (S) and chloride ion (Cl ? deprivation in a growth medium; however, it may not be realistic to control S or Cl concentrations natural sources (e.g., wastewater). In this study, two different green algal species, Chlamydomonas...

Strain HIL Y-9031725 was isolated from a soil sample collected in India. The strain was identified as belonging to the genus Streptomyces using the methods described by Shirling and Gottlieb.2) A loopful of mature slant culture of Streptomyces Y-9031725 was inoculated into Erlenmeyer flasks (500 ml capacity) containing 100 ml of seed medium consisting of glucose 1.5%, soyabean meal 1.5%, corn s...

Abstract Bioethanol production has been a challenge for the researchers with respect to enhancing bioethanol yield. In this study, we are reporting an efficient novel method produce bioethanol. The process comprises co-culture technique from wheat straw, by co-culturing Bacillus licheniformis and Saccharomyces cerevisiae. Simultaneous saccharification fermentation allows straw hydrolysis cellul...

Abstract Synthesis of assumed natural (12R,13S)-enantiomers pyriculariol (1) and dihydropyriculariol (2), phytotoxins isolated from rice blast disease fungus, Pyricularia oryzae, was achieved using Wittig reaction or microwave-assisted Stille coupling as the key step. The synthesis revealed that 1 2 are racemates. Foliar application test on a leaf indicated both salicylaldehyde core side chain ...
