As hemp is a renewable resource with the high biomass yield it could be considered as potential abundant local biomass material for a wide range of applications. In this article hemp fibres architecture as a source of high strength cellulose are analysed. In experimental part steam explosion technology is applied to disintegrate technical hemp fibres to elementary fibres with the aim to find out the best way of procedure without usage to environment harmful chemical pre-treatments and looking forward to solve problems on further nano-level environment friendly hemp cellulose disintegration.

High Biomass Yield

Murphy is a high-yielding forage oat (Avena sativa L.) cultivar developed by Agriculture and Agri-Food Canada, Lacombe Research Centre, Lacombe, AB, and released in 2000. It is a late-maturing cultivar with high biomass yield and good lodging resistance. It was developed from a cross of Waldern/IH-1863-515. Murphy is well adapted to Alberta and the rust-free areas of Saskatchewan. Key words: Avena sativa, forage oat (spring), cultivar description

High Biomass Yield

Reed canary grass, Phalaris arundinacea L., is a relatively new biomass crop in northern Europe, which produces raw material for bioenergy and paper pulp. Breeding reed canary grass for industrial purposes is under way in the absence of domestic cultivars being available. Knowledge of the extent of variation in biomass related traits is a basic requirement of the breeding programme. The aim of this study was to describe variation in biomass related traits and evaluate the relationships among the variables. Field experiment was carried out between 1994 and 1998 in Finland. Research material included wild and elite populations, which were divided into ten groups according to their origin. Biomass yield, plant fractions, shoot number, node number, leaf area and overwintering ability were measured. Panicle number, plant height and seed ripening were included to the analyses of the relationships. Results indicated the high biomass yield potential of reed canary grass, reaching over 13 t DM ha-1 in the fourth year after establishment. Elite material and a local group from southern Finland had the highest biomass yield, whereas the northernmost local group had the lowest. Three factors established accounted for 45% of the variance and they were defined as “high biomass yield”, “leaf-shoot relationship” and “fast development”. The first factor indicated positive connections among biomass yield, panicle number, plant height, straw fraction and node fraction. This study indicated variation in agronomic traits of reed canary grass, which enables breeding of new cultivars with desired trait combinations.;

High Biomass Yield

Effect of various nitrate replete concentrations have been investigated in terms of biomass yield, cell and nitrate concentrations. Media used in this study is Bold’s basal medium which contains nitrate that act as nutrient. Its concentrations have been varied for obtaining the high biomass yield. The nitrate concentrations used were 30 mg nitrate/L, 35 mg nitrate/L, 40 mg nitrate/L, 45 mg nitrate/L and 50 mg nitrate/L) with 30 mg nitrate/L as a control. Microalgae Chlorella sp. is cultured and aerated in a Schott bottle with presents of light. Results showed that the best concentration to obtain highest biomass yield was 45 mg nitrate/L. It also gave the highest optical density reading at day 9 with 2.100 ± 0.070 and showed the highest cell concentration with 703 ± 29 x 106 cells/mL. Dry algae produced by this concentration after the end of the cycle was 291 ± 9 mg which was the highest compared to other concentration. It is suggested that as the biomass yield is increased by using 45 mg nitrate/L concentration, other methods to increase lipid content can be paired with nitrate replete method and can be further studied in the future.

High Biomass Yield

Sweet sorghum has the advantage to grow on saline-alkaline barren land, and is very suitable to plant in Gansu province for different uses such as feedingstuff and fermentation material. However, in the previous test, it was found that the biomass of Saccharomyces cerevisiae using sweet sorghum juice produced in Gansu province was as low as 8.5 g/l and could not meet the needs of mass production of yeast and ethanol. To attain high biomass, the optimal culture conditions were investigated. It was found that the proper culture time, temperature, pH and sugar content for yeast growth in sweet sorghum juice were 20 h, 30 °C, 6.0 and 80.5 g/l, respectively. An orthogonal design L9 (34) was used to test the optimal inorganic salt supplement quantity. The results showed that high biomass yield was achieved when the juice was supplemented with 2.0 g/l (NH4)2SO4 which was a little bit different from other report. Finally, the biomass yield of 19.3 g/l and conversion efficiency (yeast to sugars) of 0.452 was obtained in a 10-100 liter bioreactor under the determined optimal conditions. These findings demonstrate that with some modifications on the culture conditions, sweet sorghum juice is a very potential substitute of fermentation material for yeast and ethanol production in Gansu province.
