Sophorolipids (SLs) production by the yeast Candida bombicola was studied in batch shake flasks using synthetic dairy wastewaters (SDWW) with or without any added external carbon and nitrogen sources. A maximum SLs production of 38.76 g/l was observed with the SDWW supplemented with low cost substrate of sugarcane molasses at 50 g/l and soybean oil at 50 g/l. When the SDWW was supplemented with...

Certain amino acids inhibit growth of tobacco (Nicotiana tabacum L. var. xanthi), tomato (Lycopersicon esculentum) carrot (Daucus carota), and soybean (Glycerine max L. co. Mandarin) cell cultures when nitrate or urea are the nitrogen sources but not when ammonia is the nitrogen source. These amino acids also inhibit development of nitrate reductase activity (NADH:nitrate oxidoreductase EC 1.6....

A pot experiment using root separation technique was conducted to further understand the effect of root interaction played in intercropping system under different nitrogen levels. The results showed that root interaction and increasing nitrogen application increased the green leaf area per plant and chlorophyll content of soybean, but their effects gradually decreased with increasing nitrogen f...

to survey the effects of flooding during the reproductive growth stages of aerenchyma formation and ethylene production in soybean cultivar dpx experiment  the completely randomized factorial was in 2012 in gorgan university of agricultural sciences and natural resources. factors examined include nutrition levels in three levels (1 - inoculated with bacteria japonicumbradyrhizobium 2 - non-inoc...

Biosurfactant production by Pichia anomala PY1, a thermotorelant strain isolated from fermented food, was examined as grown in media containing various carbon and nitrogen sources. The optimal conditions for biosurfactant production included 4% soybean oil as carbon source at pH 5.5 at 30 degrees C for 7 d. Under these conditions, the surface tension of the medium decreased to 28 mN/m with oil ...

Two experiments were conducted to evaluate the effects of adding fiber sources to reduced-crude protein (CP), amino acid-supplemented diets on N excretion, growth performance, and carcass traits of growing-finishing pigs. In Exp. 1, six sets of four littermate barrows (initial weight = 36.3 kg) were allotted randomly to four dietary treatments to determine N balance and slurry composition. Diet...

Drought is considered to be a major threat to soybean production worldwide and yet our current understanding of the effects of drought on soybean productively is largely based on studies on above-ground traits. Although the roots and root nodules are important sensors of drought, the responses of these crucial organs and their drought tolerance features remain poorly characterized. The symbioti...

Recently detected but unidentified cytokinin activity in crown gall tumor tissue from Vinca rosea L. grown on media containing sources of reduced nitrogen has now been attributed to two adenine-type cytokinins. These compounds are glucopyranosyl derivatives of zeatin and ribosylzeatin. The substitution in each case is on the isopentenyl chain of the parent compound. Neither of these compounds h...
