a stable agrobacterium-mediated transformation system was established using bialaphos as the selective agent in soybeans [glycine max (l.) merr.]. the cotyledonary node explants of the soybean cultivar ‘ny-1001’ were inoculated with the agrobacterium tumefaciens strain eha105, harboring the vector pcambia3301 containing the gus gene as the reporter gene and the bar gene conferring bialaphos res...

using productivity index for investigating a firms’ performance makes it possible to evaluate efficiency of the production system and cost at the same time. in this study the total factor productivity (tfp) of several sugar cane varieties in imam khomeini cultivation and processing center in khuzestan province is compared. two hundred and forty eight farms are categorized on the basis of variet...

The System of Rice Intensification (SRI), a water-saving paddy cultivation system, has been implemented in Indonesia. application SRI can increase water productivity. Salibu method applied to save seeds, costs, labour and the planting index paddy. However, when used other areas, yield is reduced by up 50 per cent from first harvest. A combination management needed production. this research expe...

Soil cultivation is commonly used to manage organic matter (OM) accumulation in golf course putting greens. Our objectives were to determine: (i) if hollow-tine cultivation is more effective than solidtine cultivation at managing OM and water infiltration, (ii) if venting methods are effective at managing OM and water infiltration, and (iii) if venting alters or interacts with effects of earlyo...

Rice is the staple food in Tamil Nadu and is grown in an area of 2.6 Mha with a production of 8.19 Mt and productivity of 3.2 t/ha. In the context of high water demand by rice farmers, any strategy that would produce higher rice yield with less water is the need of the day. One such system is “System of Rice Intensification” (SRI), which was developed by Fr. Henri de Laulanie in Madagascar in 1...

2015 Aim: Bioreactors are an essential component in every biotechnological process. Due to the multitude of different microbial and mammalian organisms used for production of complex products, novel concepts for customized cultivations are necessary. Results: A ceramic capillary-based bioreactor enabling a novel approach for steadystate biofilm cultivation is presented. A model for the determin...

BACKGROUND The 'attached cultivation' technique for microalgae production, combining the immobilized biofilm technology with proper light dilution strategies, has shown improved biomass production and photosynthetic efficiency over conventional open-pond suspended cultures. However, how light is transferred and distributed inside the biofilm has not been clearly defined yet. RESULTS In this r...

Background Consolidated bioprocessing (CBP) has attracted increasing attention since it can accomplish hydrolytic enzymes production, lignocellulose degradation and microbial fermentation in one single step. Currently, biobutanol is mainly produced by mesophilic and solventogenic clostridia, such as Clostridium beijerinckii and C. acetobutylicum, which cannot directly utilize lignocellulose, an...
