The Gerber method is used worldwide as a simple and rapid for determining fat in raw processed milks. However, the volume of test portion has not been internationally agreed upon. A collaborative study was conducted to evaluate performance using either weighed (11.13 g) or by 10.77 mL delivered pipet. For each method, laboratories received 10 samples: 5 pasteurized homogenized milks, 2 which were blind duplicate pairs. Eleven participated evaluation aliquot addition weight pipet,...
Abstract Raw glycerol, the main by‐product of bio‐diesel production process, was converted to 1,3‐propanediol by Clostridium butyricum F2b. In batch cultures, 47.1 g dm −3 were produced. Continuous cultures conducted at a constant dilution rate (= 0.04 h −1 ) and various inlet glycerol concentrations with produced levels up 44.0 . At increasing in medium, biomass yield decreased. This decrease attributed microbial metabolism being directed towards biosynthesis organic acids (and hence carbon...
Abstract Corynebacterium glutamicum is well known as an important industrial amino acid producer. For a few years, its ability to produce organic acids, under micro‐aerobic or anaerobic conditions was demonstrated. This study focused on the identification of culture parameters influencing acids production and, in particular, succinate production, by this bacterium. 2262, used throughout study, wild‐type strain, which not genetically designed for succinate. The oxygenation level and residual...
Continuous crystallization of calcium lactate pentahydrate was investigated in a mixed-suspension-mixed-product removal crystallizer. Wide ranges the mean residence time, relative supersaturation, and magma density were covered (40−215 min, 0.01−1.12, 2−65 kg/m3, respectively). Crystal growth found to be dependent on crystal size. The Abegg, Stevens, Larson model Mydlarz Jones tested for determination kinetics parameters from experimental results. Zero-size larger size rate values order...
Abstract The fermentative properties of thermo-sensitive strain Corynebacterium glutamicum 2262 were investigated in processes coupling aerobic cell growth and the anaerobic fermentation phase. In particular, influence two modes on production lactate, product model, was studied. both processes, lactate produced significant amount, 27 g/L batch culture, up to 55.8 fed-batch but specific rate culture four times lower than that culture. Compared other our strategy resulted highest yield lactic...
