The impact of a tapioca-based artificial diet on the developmental rate, life history parameters, and fertility was examined over five consecutive generations for the cotton bollworm, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae), a highly polyphagous pest of many agricultural crops. The study showed that when fed the tapioca-based artificial diet during larval stage, larval and pupal de...

Tapioca starch, poly(lactic acid), and Cloisite NA+ nanocomposite foams, with four clay contents (1, 3, 5, 7, wt %), were prepared by melt-intercalation method. Selected structural, thermal, physical, and mechanical properties were characterized using X-ray diffraction (XRD), scanning electron microscopy, differential scanning calorimetry, and an Instron universal testing machine, respectively....

This paper describes optimization of fermentation conditions for the production of thermostable pullulanase from a new strain Bacillus cereus FDTA 13, isolated from tapioca soil. By using one-factor-at-a-time and orthogonal array method, a simple medium with effective and minimal components was optimized for maximal pullulanase production. The optimized medium containing (in g/L): starch 20, ye...

This study attempted to assess the influence of mechanical forces on potato, tapioca, wheat, rice, and maize starch granules. For this purpose, we used digital analysis microscopic images granules before after grinding using ImageJ software. Additionally, studied temperature size shape by drying starches for 30 min at 60 °C. Our results indicate that very rarely cause damage granules, such as b...

Gas production (GP) and starch degradation (STAD) from starchy feedstuffs were measured simultaneously by in-vitro incubation in buffered rumen fluid after 0, 4, 6, 8, 12, 16 and 24 h incubation to explore the possibility to estimate STAD via GP technique for starchy feedstuffs. The results showed the ranking in the initial degree of starch degradation and gas production. Potato starch and maiz...
