BACKGROUND L-tryptophan is an important ingredient in medicines, especially in neuromedicines such as antidepressants. Many commercial processes employ various microorganisms with high tryptophan synthase activity to produce L-tryptophan from indole and L-serine, but these processes are very costly due to the costs of precursors, especially L-serine. OBJECTIVES For this reason, we studied the...

The waste formed during sugar- and wine-making activities has attracted our attention given its ability to inhibit corrosion in the presence of brine a de-icing formulation. Herein addition amines de-sugared beet molasses winery lees is found improve their anti-corrosive properties. Thus, weight-loss experiments clearly show that small amount or results marked inhibition on carbon galvanized st...

Determination of the amount of sugar in sugar beet is usually accomplished by polarimetric method in sugar industry. This method is not accurate due to impurities such as sodium, potassium and amino-nitrogen that are present and might cause some errors in the evaluation of the technical quality of sugar beet. In this research, 7309 samples of sugar beet from two semi- arid county, Isfahan and C...

In this study fungi isolated from the effluent of ethanol factories were identified. Optimal conditions for single cell protein (SCP) production and COD reduction of sugar beet stillage are specified for a species of Hansenula in a continuous culture. Under these conditions 5.7 g dm-3 biomass was produced and 31% of COD was reduced without addition of further nutrients to the beet molasses ...

Soil salinity adversely affects the growth, yield, and quality parameters of sugar beet, leading to a reduction in root yields. Improving physical chemical properties salt-affected soils is essential for sustainable cultivation beet production. A field experiment was conducted at Delta Sugar Company Research Farm, El-Hamool, Kafr El-Sheikh, Egypt, evaluate response application filter cake treat...

alcohol in iran is produced mainly from molasses of sugar cane and sugar beet. other sources of alcohol production like wheat and barley exist, but because of some cultural and political reasons, they cannot be legally used for producing alcohol in iran. twenty-six manufacturers in 18 provinces are officially active. the actual capacity of ethanol production with medical purity is about 100mill...

Beet molasses successfully replaced glucose as sole carbon source to produce poly-b-hydroxybutyrate by a recombinant Escherichia coli strain (HMS174/pTZ18u-PHB). The fermentation with molasses was cheaper than with glucose. The final dry cell weight, PHB content and PHB productivity were 39.5 g/L, 80% (w/w) and 1 g/Lh, respectively, in a 5 L stirred tank fermenter after 31.5 h fed-batch ferment...
