Properties of particleboard produced from discard sawdust and cassava waste blends

Nine weaned White Fulani Calves aged between 3 - 13 months, weighing between 28 - 71kg werte fed on ratios consisting of basal Guinea grass hay and 0, 15, 30% Albizia saman replacement for cassava waste in a concentrate ration and each period lasting 28 days feed intake and live weight changes of White Fulani Calves were determined. The DM intake increased with increased level of Albizia saman in the ration, the highest liveweight changes was recorded when the animals were fed 30% Albizia saman whole pod. The result showed that Albizia saman whole pod promotes intake and live weight changes of White Fulani calves, thus can be fed without any adverse effect on calves.

We investigated the influence of corn steep liquor (CSL) and cassava waste water (CWW) as carbon and nitrogen sources on the morphology and production of biomass and chitosan by Mucor subtilissimus UCP 1262 and Lichtheimia hyalospora UCP 1266. The highest biomass yields of 4.832 g/L (M. subtilissimus UCP 1262) and 6.345 g/L (L. hyalospora UCP 1266) were produced in assay 2 (6% CSL and 4% CWW), factorial design 22, and also favored higher chitosan production (32.471 mg/g) for M. subtilissimus. The highest chitosan production (44.91 mg/g) by L. hyalospora (UCP 1266) was obtained at the central point (4% of CWW and 6% of CSL). The statistical analysis, the higher concentration of CSL, and lower concentration of CWW significantly contributed to the growth of the strains. The FTIR bands confirmed the deacetylation degree of 80.29% and 83.61% of the chitosan produced by M. subtilissimus (UCP 1262) and L. hyalospora (UCP 1266), respectively. M. subtilissimus (UCP 1262) showed dimorphism in assay 4–6% CSL and 8% CWW and central point. L. hyalospora (UCP 1266) was optimized using a central composite rotational design, and the highest yield of chitosan (63.18 mg/g) was obtained in medium containing 8.82% CSL and 7% CWW. The experimental data suggest that the use of CSL and CWW is a promising association to chitosan production.

Cassava Waste

Optimization of the growth condition for maximum growth rate and protease production was carried out using Bacillus subtilis. The optimization of protease production using agro industrial waste product such as cassava waste as substrate was performed with statistical methodology based on experimental designs. The screening of twelve nutrients for their influence on protease production was achieved using a Plackett-Burman design. MgSO4.7H2O, casein and glucose were selected based on their positive influence on protease production. The selected components were optimized using Response Surface Methodology (RSM). The optimum conditions are (% w/w): MgsO4.7H2O- 0.14, casein- 1.4 and glucose- 2.64. These conditions were validated experimentally which revealed an enhanced protease yield of 202.048 U/gds.
