TL;DR: Various properties of biodiesel obtained from chlorella sp.
Abstract: Microalgae based biofuels are getting attention due to energy crisis and enviromental protection. In the present study, the Chlorella sp. was cultivated in BG-11 medium at batch mode. The effect of different nitrogen (sodium nitrate, potassium nitrate and urea) and organic carbon (glucose, glycerol and sucrose) sources were analyzed on growth and lipid accumulation on this species. The highest biomass growth and biomass productivity of chlorella sp. was found 1.29±0.04 g/l, 76.96±4.5mgl -1 d - 1 in urea. However in case of organic sources, the biomass growth and productivity was found maximum in glucose (1.43±0.075 g/l 86.04±3.2 mgl -1 d -1 ). The lipid content was examined using folch method and found better in potassium nitrate nitrogen source (11.84%) . Among organic carbon sources, the maximum lipid content (13.22% and lipid yield 189.94 mg/l were found in case of glucose, followed by glycerol and sucrose. Various properties of biodiesel obtained from chlorella sp. such as Cetane number, Saponification value, Iodine value and Degree of unsaturation were followed standerds set by the national petroleum agency (ANP255), ASTMD6751 and EN14214. Keywords: Biodiesel, Biomass growth, Chlorella sp., Lipid extraction, Transesterification

TL;DR: In this paper, a special controlled-release water soluble fertilizer for grapes and a preparation method of the special controlled release water-soluble fertilizer is presented. But the method is not suitable for grapes.
Abstract: The invention relates to a special controlled-release water soluble fertilizer for grapes and a preparation method of the special controlled-release water soluble fertilizer. The controlled-release water soluble fertilizer is prepared from the following raw materials in parts by weight: 190-230 parts of ammonium nitrate, 40-60 parts of ammonium dihydrogen phosphate, 30-50 parts of triple superphosphate, 90-110 parts of monopotassium phosphate, 230-260 parts of potassium nitrate, 100-130 parts of potassium sulfate, 30-60 parts of chelated medium trace element mixture, 7-10 parts of borax and 3-6 parts of inorganic gel particle. The preparation method comprises the following steps: (1) treating monopotassium phosphate and potassium sulfate by use of the inorganic gel particle to obtain controlled-release monopotassium phosphate and potassium sulfate; and (2) mixing and dispersing the raw material components at a high speed to obtain the controlled-release water soluble fertilizer. According to the special controlled-release water soluble fertilizer for grapes, a part of phosphorus and potassium nutrients in the controlled-release water soluble fertilizer have slow release feature, so that the water soluble fertilizer is in accordance with the law of the nutrient absorption in a grape growth period, the fertilizer efficiency utilization rate of the water soluble fertilizer is improved and the controlled-release water soluble fertilizer has high market application value.
