Faculty of Pharmacy, Suez Canal University, Ismailia, Egyptīiocatalysis is crucial for a green, sustainable, biobased economy, and this has driven major advances in biotechnology and biocatalysis over the past 2 decades.Weight (CDW) containing 94% PHA in shake flask studies. bluephagenesis TDHCD-R3 by overexpressing an optimized phaCAB operon was able to grow to 15 g/L cell dry bluephagenesis TDHCD-R3-8-3 constructedįrom H. Metabolites including acetate, formate, lactate and ethanol compared to wild-type. bluephagenesis TDHCD-R3 obtained after 3 rounds of selection showed an obvious enhancement of resistance to toxic Based on an error-prone DNA polymerase III ε subunit, a genome-wide random mutagenesis system was establishedĪnd used in conjunction with an artificial high cell density culture environment during the selection process. A selection strategy for mutant strains that can grow to a high cell density wasĭeveloped. Platform bacterium for the next generation of industrial biotechnology with a native PHA synthetic pathway, able to grow under Halomonas bluephagenesis TD01 is a halophilic High-cell-density cultivation is an effective way to improve the productivity of microbial fermentations and in turn reduce theĬost of the final products, especially in the case of intracellular products. This article briefly describes the available techniques and various applications in inoculum preparation. This is crucial for achieving maximum viral yield. Viral cultures require processing of various samples by decontamination, concentration, and addition of appropriate solution to obtain working inoculum, which is added to relevant cell lines. McFarland standard, used since decades, and other recently launched automated systems are required to define the density of inoculum for the same. Antibiotic susceptibility methods, as standardized by Clinical Laboratory Standards Institute (CLSI), involve the preparation of pure culture of a single type of organism at specific cell density, which constitutes the inoculum. Inoculum standardization has a bearing on medical and research microbiology also. In the preparation process, biomass is monitored, which involves sensors, exhaust gas analysis, and mass spectrophotometers. Inoculum quality is further enhanced by strain improvement and cell immobilization technology. Adequate culture and production medium are essential for providing the right environment for inoculum. Industrial biotechnology pdf free#A proper inoculum must be at active growth stage and size, free from contamination, and have product-forming ability. enzymes, beverages, drugs, toxins, vitamins, amino acids, organic acids, solvents, food products, and recombinant proteins. This has application in industrial microbiology for obtaining products such as antimicrobials. The prime objective is usually to achieve a high level of viable biomass in a suitable physiological state for use as an inoculum. Inoculum preparation involves obtaining the organisms in an optimal state that is compatible with inoculation into cell culture, tissue culture, media, and fermentors. Module 4 deals with the scope of industrial microbiology, Immobilization of cells and Industrial use of enzymes. Module 3 explains about Fermentor / Bioreactor, Types of Fermenters / Bioreactors, Bioreactor control, Bioreactor instrumentation and sterilization, Mode of culturing microorganisms and Downstream processing (DSP). In module 2, Media classification and bacterial nutritional requirements, Defined vs undefined media, Fermentation broth, Designing fermentation media, Effect of pH, temperature and salt concentration in fermentation, Media optimization, Fermentation starter / starter culture and Media for identifying microorganisms. Module 1 deals with Bioprocess and Chemical process, Introduction to Industrial Biotechnology (IBT) or Bioprocess technology (BPT), Microbial growth, nutrition and kinetics, Microbial metabolism and industrially important microbial metabolites, Fermentation: definition, types and applications, Isolation and screening of industrially important microorganisms and strain improvement. Production of a commercially useful chemical or fuel by a biological process, such as microbial fermentation or degradation. A bioprocess is any process that uses complete living cells or their components to obtain desired products.
