The study was conducted to evaluate the quality characteristics of cookies produced from sweet potato-fermented soybean flour. Cookies were subjected to proximate and sensory analysis to determine the acceptability of the product. Protein, fat and ash increased as the proportion of soybean flour increased, ranging from 13.8-21.7, 1.22-5.25 and 2.20-2.57 respectively. The crude fibre content was...

abstract in order to study of chemical and mechanical weed management methods and their integration in potato (solanum tuberosum), a field experiment was done in 2008 at ferdowsi university of mashhad research field. experimental design was completely randomize block design with 6 treatments and 3 replications. treatment included broadcast herbicide application (standard treatment), between row...

Life-cycle assessment (LCA) was used to evaluate the energy efficiency and environmental impacts of sweet potato-based bioethanol production. The scope covered all stages in the life cycle of bioethanol production, including the cultivation and treatment, transport, as well as bioethanol conversion of sweet potato. Results show that the net energy ratio of sweet potato-based bioethanol is 1.48 ...

Solanesol is a high value 45-carbon, unsaturated, all-trans-nonaprenol isoprenoid. Recently solanesol has received particular attention because of its utility, both in its own right and as a precursor in the production of numerous compounds used in the treatment of disease states. Solanesol is found mainly in solanaceous crops such as potato, tomato, tobacco and pepper where it accumulates in t...

The potato tuberworm, Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae), is a serious pest of the potato, Solanum tuberosum L. (Solanales: Solanaceae), in both fields and stores in tropical and subtropical regions. In the present study, the susceptibility of different potato cultivars to P. operculella was evaluated by measuring life table parameters. Tests were undertaken with leaves a...

A chimeric gene containing the patatin promoter and the transitpeptide region of the small-subunit carboxylase gene was utilized to direct expression of Escherichia coli glycogen synthase (glgA) to potato (Solanum tuberosum) tuber amyloplasts. Expression of the glgA gene produd in tuber amyloplasts was between 0.007 and 0.028% of total protein in independent potato lines as determined by immuno...

BACKGROUND Lactic acid is an important biorefinery platform chemical. The use of thermophilic amylolytic microorganisms to produce lactic acid by fermentation constitutes an efficient strategy to reduce operating costs, including raw materials and sterilization costs. RESULTS A process for the thermophilic production of lactic acid by Geobacillus stearothermophilus directly from potato starch...

the potato tuberworm, phthorimaea operculella (zeller) (lepidoptera: gelechiidae), is one of the most damaging pests of cultivated potato (solanum tuberosum l.) crop, in both field and stores in tropical and subtropical regions. the biological parameters of this pest were evaluated in the growth chamber at 24±1ºc, 65±5% rh and photoperiod of 14:10 h (l:d) on leaves of ten potato cultivars, agri...
