Pasteurella spp. are Gram-negative facultative bacteria that cause severe economic and animal losses. Pasteurella-based vaccines the most promising solution for controlling outbreaks. Remarkably, insufficient biomass cultivation (low cell viability productivity) lack of knowledge about process have impacted bulk production vaccines. Bioprocess optimization in shake flask bioreactor is required ...

Abstract The structure and physicochemical properties of starch isolated from the cotyledon hull faba beans wheat (as reference) were examined using 16 different methods. amylose content in bean was 32% 36%, respectively, that 21%. structurally alike both displaying C-polymorphic pattern, a similar degree branching branch chain length distributions. Wheat had significantly greater prevalence sh...

in order to investigation some soil characteristics and filed age effects on flower and corm yield of saffron, an experiment was conducted as factorial based on complete randomized design with five replications in two regions of neyshabur during growing season 2009-2010. treatments were included different filed ages (2, 4 and 6 years) and two geographical regions (eshagh abad and soltan abad). ...

Injectable PEG-analogue hydrogels based on poly(oligoethylene glycol methacrylate) have been developed based on complementary hydrazide and aldehyde reactive linear polymer precursors. These hydrogels display the desired biological properties of PEG, form covalent networks in situ following injection, and are easily modulated for improved control over their functionality and physiochemical prop...

Mycoplasma hyorhinis organisms were fractionated into lipid, carbohydrate, and protein fractions by chemical and physiochemical procedures. When all fractions were tested for complement fixation and inhibition of growth inhibition activity, only the protein fractions possessed activity. Thus, it appears that the major antigenic component of M. hyorhinis is a protein.
