The production of kanamycin by three species of Streptonbyces and four fermentation media was studied. Streptomyces canus in medium No. 2 gave the highest yields of kanamycin aftrr 72 hrs. of fermentation. The presence of both molasses and glucose in the fermentation mcdium was an important factor for the production of kanamycin. The best concentration of molasses and glucose were 15.0 and 10.0...

Gray molasses is a powerful tool for sub-Doppler laser cooling of atoms to low temperatures. For alkaline atoms, this technique is commonly implemented with cooling lasers which are blue-detuned from either the D1 or D2 line. Here we show that efficient gray molasses can be implemented on the D2 line of K with red-detuned lasers. We obtained temperatures of m ( ) 48 2 K, which enables direct lo...

A series of feeding experiments were undertaken with weaner cattle to assess the effects on liveweight performance of supplementing a basal diet of molasses, urea and roughage with various protein and energy supplements. The supplements included extruded soyabeans, a mixture of extruded soyabean and crushed maize grain, or soyabean and crushed maize extruded together. These experiments indicate...

introduction: pragmates australis (pa) (common reed) is a riverside perennial grass found in wetlands throughout temperate and tropical regions of the world. pa grows in many wetlands around rivers in iran. animal feed restriction is the main problem of iranian animal production systems and this feed resource can be fed to native livestock especially in rural areas. ensiling pa could improve it...

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...

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...

Substrate type is one of the major factors affecting growth and yield oyster mushroom (Pleurotus ostreatus). Five substrates; Finger millet husk, Fingermillet husk + Molasses, Rice bran, Wheat +Mustard oilseed cake, were evaluated for productivity mushroom. The experiment was conducted in a completely randomized design with each treatment replicated seven times. Additives added on finger @5% it...
