Pullulan production from Aureobsidium pullulans by continuous culture
Ten isolates of Aureobasidium pullulans were screened for the highest production of pullulan and minimal melanin production from Fayoum Governorate, Egypt. The optimum conditions for continuous culture were studied; temperature was 24°C, while pH 5.0, and agitation speed was at 500 rpm, while the aeration rate was 2.5 vvm and the best flow rate was 1 L/ 24 h. The maximum production of pullulan ...
متن کاملContinuous gluconic acid production by Aureobasidium pullulans with and without biomass retention
Abbreviations: Conversion (%): [(g consumed glucose/g feeding glucose) x 100], dilution of medium glucose by NaOH feeding was considered in the calculations mp: Specific gluconic acid productivity, [g gluconic acid/(g biomass x h)], Rj [g/(l x h)]/biomass concentration (g/l), g/(g x h) Rj: Formation rate of the generic product (volumetric productivity), g gluconic acid/(l x h), gluconic acid co...
متن کاملThe Study on Microbial Polymers: Pullulan and PHB
Microbial cells are producers of natural polymers present in plant cells. Production of pullulan (an extracellular microbial polysaccharide) by Aureobasidium pullularia pullulans (P. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. Pullulan formation obeyed a growth and non-growth associated term. PHB (polyhydroxybutyrates) an intracellular biopo...
متن کاملMedium for toxin production by Clostridium perfringens in continuous culture.
A tryptone-salts medium for continuous growth and alpha toxin production of Clostridium perfringens type A in an adapted chemostat is described. In such steady-state cultures, fermentative and biochemical activity of C. perfringens remained unchanged. Toxigenic ability to produce alpha, theta, and nu toxins was preserved.
متن کاملRelation of capsular polysaccharide production and colonial cell organization to colony morphology in Vibrio parahaemolyticus.
Vibrio parahaemolyticus is a ubiquitous, gram-negative marine bacterium that undergoes phase variation between opaque and translucent colony morphologies. The purpose of this study was to determine the factor(s) responsible for the opaque and translucent phenotypes and to examine cell organization within both colony types. Examination of thin sections of ruthenium red-stained bacterial cells by...
