Bioethanol production is one of cereal’s using ways. COM 2003/30/EC: Directive on the promotion of the use of biofuels or other renewable fuels for transport orders that proportion of biofuels in 2010 must be -5.75% but in 2020 – 10%. The object of research is to study the influence of winter crops cultivation’s technology on quality of grain and suitability for bioethanol production. Field research was organized in the Agricultural Science Centre of Latgale from 2005 to 2008. There were researched 5 fertilizer rates and the influence of varieties on the grain yield and starch in the experiment for 3 years. Starch content, yield and the result of bioethanol have changed depended on species of cereals, varieties, growing year and fertilizer rate. It is recommended to use good quality grains with high starch content and low protein content for bioethanol production.

The yield and properties of ethanol biofuel produced from five different whole cassava flours were investigated. Ethanol was produced from five different whole cassava flours. The effect of quantity of yeast on ethanol yield, effect of whole cassava flour to acid and mineralized media ratio on the yield of ethanol produced, and the physical properties of ethanol produced from different cassava were investigated. Physical properties such as distillation range, density, viscosity, and flash point of ethanol produced differ slightly for different cultivars, while the yield of ethanol and electrical conductivity of ethanol from the different cassava cultivars varies significantly. The variation in mineral composition of the different whole cassava flours could also lead to variation in the electrical conductivity of ethanol produced from the different cassava cultivars. The differences in ethanol yield are attributed to differences in starch content, protein content, and dry matter of cassava cultivars. High yield of ethanol from whole cassava flour is best produced from cultivars with high starch content, low protein content, and low fiber.

Indonesia is the largest sago feedstock in the world. There are about 2 millions ha sago forest that approximately half of the world's sago forest is present in Indonesia. Naturally, sago spreads widely in Papua, while semi-cultivation is in Maluku, Sulawesi, Borneo, and Sumatra. The species sago (Metroxylon sago) was used in this study. It has a relatively high starch content (95.99%) with low amylose content (20.61%) and low protein content (1.63%). Modified sago flour is a product from sago flour that modified with fermentation to increase the nutritional value of the sago flour. It can be used as a gluten free flour and low-calorie food products. The bacteria (Lactobacillus plantarum) was used in the fermentation. However, the color of the modified sago flour is off-white, if the fermentation time is too long. Therefore, it is necessary to investigate the effect of fermentation time and initial bacteria cells number on increasing nutritive value of sago flour. The variables used were fermentation times (12, 24, and 36 h) and initial bacteria cells number (7 x 1010, 7 x 1011, 1.05 x 1012, and 3,05 1012 cells of L. plantarum). The result showed that amylose and protein content increased from 20.61% to 33,06% and from 1.41% to 4.11%, respectively, with bacterial variables of 3,5 x 1012 and fermentation time of 36 h.

Ultraviolet Aging

Starch/PBAT blown films with high ultraviolet aging resistance and excellent mechanical properties were prepared by introducing lignin with polyurethane prepolymer (PUP) as a starch modifier and physical compatibilizer and 4,4′–methylene diphenyl diisocyanate (MDI) as a crosslinker. Starch was modified by reacting the NCO groups of the PUP with the OH groups of the starch to form a carbamate bond. The mechanical properties, hydrophobic properties, ultraviolet barrier, ultraviolet aging properties and microscopic morphology of starch/PBAT films with different contents of lignin were investigated. The results showed that the starch/PBAT films were blown continuously. The addition of lignin did not decrease the mechanical properties. On the contrary, the film with 1% lignin possessed the excellent mechanical properties with longitudinal tensile strength of 15.87 MPa and the elongation at a break of 602.21%. In addition, the higher the lignin content, the better the UV blocking effect. The introduction of lignin did not affect the crystalline properties but improved the hydrophilic properties and sealing strength of the high starch content composite films.

The Cost

Context The increasing demand for maize for human food and industrial uses has stimulated research interest into alternative low value crops as energy sources for poultry. Several high yielding species of aroids, commonly known as taro or cocoyam, are currently in less demand for food or industrial uses and readily available for poultry feeding. Aims To review the production, nutritional profile and antinutritional factor and current uses of cocoyam corm and the effect of processing on its utilisation in poultry feeding. Key findings The nutritional profile of cocoyam with protein content comparable or higher than maize, high starch content and starch digestibility make it a suitable energy ingredient for poultry. The major issues affecting the utilisation of cocoyam include the high moisture and low dry matter contents and the presence of antinutritional factors, mainly calcium oxalate. These constraints may preclude the utilisation of cocoyam corm in commercial diets but it could be used to reduce the cost of production on small-holder farms. Conclusion With adequate processing and proper diet formulation, cocoyam corm meal may be fed up to 280 g/kg diet but unprocessed meal may exert adverse effects on poultry performance even as low as 44 g/kg. Several animal factors including age, species and type of bird (meat or egg) affect the utilisation of cocoyam corm meal by poultry. Implications Reduction of cost of animal protein production and value addition to underutilised aroids. More research is needed into animal factors and feed processing that would allow optimum utilisation of the corm by poultry.

Conduit Wall

Xylem embolism repair is preceded by starch depolymerisation in vessel-associated cells (VAC) of Laurus nobilis L. (laurel) twigs, but the primary signal triggering such a process is still unknown. We tested the hypothesis that conduit wall vibrations during cavitation may be sensed by VAC inducing starch-to-sugar conversion. Twigs of laurel from watered or stressed plants were exposed to ultrasound for 60 min to simulate acoustic waves emitted by cavitating conduits. Preliminary tests showed that ultrasound caused no damage to cell membrane integrity nor did they cause xylem embolism. The number of VAC with high starch content (HSC-cells) was estimated microscopically by counting the cells with more than 50% of their lumen filled with starch granules. Sonication had no effect on HSC-cells in twigs from watered plants while it induced a drop in the percentage HSC-cells from 80 to 40% in twigs from stressed plants, at the ultrasound source location. No effect was recorded in these twigs 20 mm from the ultrasound source. Sonication was a good simulator of cavitation in inducing starch depolymerisation which suggests a possible bio- physical nature for the signal initiating embolism repair.

Four groups of seven dairy cows were given hay plus high-fibre concentrates based on sugar-beet feed (hay-concentrate, 40:60 w/w) or high-starch concentrates based on flaked maize (hay-concentrate, 20:80 w/w), with a crude protein (nitrogen x 6.25) content of either 160 or 220 g/kg dry matter, over weeks 4–18 of lactation. Performance during week 3 of lactation, when all cows were fed on a standard ration, was used as a covariate. For diets with a high-fibre content, higher protein concentrations led to increases in yields of milk and milk fat, with no effect on live-weight loss. For diets with a high-starch content, higher protein concentrations did not affect milk yield or composition but resulted in an increase in live weight rather than a decrease. Diets with a high-starch content led to increased proportions of propionic acid in the rumen and increased concentrations of insulin in the blood. It is concluded that the source of carbohydrate needs to be taken into account when predicting the response to protein supply by dairy cows.
