Investigating the Usefulness of Wild Dioscorea esculenta (Wild Yam) Flour as Substrate for Citric Acid Biosynthesis
نویسندگان
چکیده
Background and Objective: The cost of substrate represents a significant percentage the total biosynthesis citric acid. There is need to continue searching for better cheap underutilize starchy raw material acid biosynthesis. Therefore, objective this research was biologically synthesis in submerged fermentation Aspergillus niger using wild Dioscorea esculenta (wild yam) tubers.
 Methodology: Submerged conducted effect concentrations, combined pretreatment membrane permeability induction on were carried out.
 Results: Citric concentration increased as yam with maximum production 10.5 ± 0.9 g/ l after 96 hours fermentation. overnight 0.3 % NaOH before at 121oC 20 minutes one time yielded 15. 0 ±1.2 g/l Calcium chloride produced 24.5 1.3 respectively fermentation.
 Conclusion: result showed that tubers can be used from enhanced by concentration, induction.

Facing herbivory on the climb up: Lost opportunities as the main cost of herbivory in the wild yam Dioscorea praehensilis
Plants with simple architecture and strong constraints on their growth may offer critical insights into how growth strategies affect the tolerance of plants to herbivory. Although Dioscorea praehensilis, a wild yam of African forests, is perennial, both aerial apparatus and tuber are annually renewed. Each year, the tuber produces a single stem that climbs from the ground to the forest canopy. ...

In vitro culture of Dioscorea wightii belongs to the family Dioscoreace. An efficient micropropagation protocol was developed for the medicinal plant Dioscorea wightii using nodal segments for axillary shoot proliferation. Callus initiation was stimulated at the basis of the explants in 100% of the cultures by 0.15-1.75μM BA, 0.75-5.0μM Kinetin, 0.15-0.30μM 2iP.The average fresh mass of calluse...

Corresponding Author Email : [email protected] The study evaluated effect of ascorbic acid and citric acid treatments on the functional and sensory properties of yam flour. Yam (Dioscorea rotundata) tubers were washed, peeled and cut into thin slices of 1cm thickness. The slices were divided into 7 portions. The 1st portion served as control. The 2nd, 3rd, 4th and 5th portions were soaked i...

Prior to the 1980s, most researchers believed that the African forest hunter-gatherers, or Pygmies, were the original inhabitants of the central African rainforests. It was assumed that their close social, economic, and ecological relationships with neighboring agricultural societies did not date back long, and that they had previously lived solely through foraging wild forest products. The sam...
