Production of lysine by Corynebacterium glutamicum (PTCC 1532) from different agricultural by-products (molasses and pulpy waste date) was compared to glucose as raw materials. For this purpose, ammonium sulphate was selected as a constant nitrogen source. The effect of different nitrogen sources was also investigated with glucose as a constant carbon source. The production of L-lysine was exam...

Crab waste preserved with .2% NaOCl was mixed with wheat straw, liquid molasses, and water (32:32:16:20, wet basis) and ensiled for a minimum of 8 wk with microbial inoculant. A reduction in pH and water-soluble carbohydrates (WSC) and a higher concentration of lactic acid (4.9%, DM basis) were achieved. The trimethylamine (TMA) concentration in the silage was 11.2 mg N/100 g. In a digestion tr...

Large amounts of untreated waste water of baker’s yeast industry from the Sudanese fermentation industry (SFI) are discharged in two different forms; molasses waste (MW) and wastewater from all processing operations. The objectives of the present study were to determine the chemical and physical properties of the wastewater from (SFI). Part of these characteristics is considered as parameters f...

Lignocellulosic biomass-derived sugars are considered nowadays to be an economically attractive carbohydrate feedstock for large-scale fermentations of bulk chemicals such as lactic acid. In the present study, corncob molasses containing a high content of xylose, which is one of the lignocellulosic biomasses and a waste by-product from xylitol production, was used for L-lactic acid production v...

Molasses is one of the most important by-products in sugar industry, which contains a large amount of sucrose. The routine way to separate the sucrose from molasses is using steffen method. Whereas this method is very usual in sugar factories, the aim of this research is optimization of this method. Mentioned optimization depends to three factors of reactor alkality, reactor temperature and dil...

these authors considered K.F. to be an acceptable The Karl Fischer and a gas chromatographic method for final molasses. Errors due to atmospheric method of water determinations are described. These and fading end-points can be overcome by two methods are with the vacuum oven instrumental methods. and Kviesitis13 has shown that method for the measurement of water in final molasses. stable end-po...
