Culture of plant

Abstract: PURPOSE: To promote growth of plants by applying a sugaralcohol such as arabitol or mannitol to plants by a method such as watering the sugaralcohol in an aqueous solution to soil, using the sugaralcohol and a liquid fertilizer of water culture, spraying the sugaralcohol upon leaf face or spraying seeds with the sugaralcohol. CONSTITUTION: A sugaralcohol such as arabitol, mannitol, pentaerythritol, myoinositol, perseitol sorbitol, further dulcitol in seaweeds, ribitiol in riboflavin, etc., is applied to plants to promote growth. The concentration of sugaralcohol is 1-4kg/ha in the case of watering to soil, 10-300ppm in the case of using both the sugaralcohol and a liquid fertilizer of water culture, 1-80mg per hill every seven days in the case of application to leaf faces and 50-1,000μg/granule in the case of coating of seeds. The sugaralcohol promotes growth of roots and stems and leaves of plants and exerts good influence on improvement in dextrose equivalent of fruit, increase in starch and protein contents of storage tissue, etc. COPYRIGHT: (C)1989,JPO&Japio

13C-NMR studies on the influence of pH and nitrogen source on polyol pool formation in Aspergillus nidulans

Abstract: The composition of the polyol pools in Aspergillus nidulans mycelium during active growth on sucrose depends strongly on pH. At pH 2.5, only mannitol is present. A comparison between nitrate- and ammonium-grown cultures shows stimulation of the arabitol content with nitrate a former nitrogen source. When starved mycelium is incubated either with natural-abundance or 13C-enriched glucose, label appears rapidly in mannitol and arabitol, regardless of the nitrogen source or the pH used.

Production of saccharide or sugarlcohol fatty acid ester by enzymatic method

Abstract: PURPOSE: To produce the titled substance without requiring a heating process, by dissolving an acetylated saccharide or sugaralcohol in an organic solvent, adding lipase to the solution and incubating CONSTITUTION: A saccharide such as glucose, fructose, ribose, arabinose, etc, and a sugaralcohol such as sorbitol, mannitol, arabitol, etc, are acetylatedThe prepared acetylated substance and a fatty acid such as caproic acid, lauric acid, linolenic acid, etc, are dissolved in an organic solvent such as benzene, toluene, acetone, etc, lipase is added to the solution and incubated The ratio of saccharide or sugaralcohol acetate and the fatty acid in the mixture is about 1:3W3:1, the concentration of a substrate in the organic solvent is about 1W2% and the amount of the enzyme is preferably about 01W10% based on total weight of the substrate The prepared ester shows lipophilic nature and is usable for conventioned uses by deacetylation COPYRIGHT: (C)1988,JPO&Japio

[35] Polyhydric alcohol transport by bacteria

Abstract: Publisher Summary This chapter discusses poluhydric alcohol transport by bacteria. For most bacteria, the polyhydric alcohols, abbreviated as polyols hereafter, are excellent carbon sources. These include the three hexitols D -mannitol, D -glucitol (formerly D -sorbitol), or galactitol (formerly dulcitol) found abundantly in natural environments, and the pentitols D - and Larabinitol (formerly arabitol), ribitol (formerly adonitol), and xylitol. In bacteria metabolism of these polyols has been shown to be initiated either (1) by dehydrogenation of the free intracellular polyol to the corresponding ketose, or (2) by the vectorial phosphorylation of the polyol to the corresponding phosphate ester concomitant with its translocation across the membrane in a process called group transiocation. In the former cases the polyols are taken up through active transport systems, and accumulated in a chemically unaltered form in the cells. This type of transport and metabolism is characteristic for pentitols in the enteric bacteria, for all polyois in most obligate aerobes, and for the heterofermentative lactobacilli. The transport process is fully reversible and most likely coupled to ion gradients.

Production of polyhydric alcohol by fermentation using novel microorganism

Abstract: PURPOSE: To obtain the titled alcohol having excellent conversion (sugar-based yield) and high practicality, by inoculating a specific microbial strain in a medium composed of carbon source, etc., and culturing under aerobic condition. CONSTITUTION: Brettanomyces sp. SN-88 strain (FERM P-7595) belonging to Brettanomyces genus and having the following microbiological properties is separated from blackstrap mollasses of a sugar manufacturer in Okinawa prefecture, Japan. Vegetative cell has ellipsoidal or sharpened ellipsoidal form of (3W7)×(4W9)μ in size; proliferating by multipolar budding; free from formation of ascospore, mycelia and pseudomycelia; producing organic acid; free from fermentation of lactose, etc.; fermenting glucose, etc., to produce polyhydric alcohols such as arabitol, etc. The strain is inoculated in a liquid medium composed of 10W40wt% sugars such as glucose, soybean flour, phosphoric acid, etc., and cultured at 32W40°C and 6W10pH for 14W20 days aerobically under agitation. The polyhydric alcohol accumulated in the culture liquid is separated by centrifugal separation, ion exchange resin treatment, extraction, concentration, etc. COPYRIGHT: (C)1987,JPO&Japio

Carbohydrate metabolism of the sugarcane smut fungusUstilago scitaminea

Abstract: Ustilago scitaminea synthesizes specific carbohydrates, mainly erythritol and mannitol, plus smaller quantities of arabitol, inositol, and trehalose. Intensive secretion of erythritol is obtained when the fungus is grown in liquid culture. Glucose, fructose, or sucrose can be used interchangeably as carbon sources by the fungus, sucrose being quickly inverted.

Novel microorganism and preparation of polyhydric alcohol by fermentation using same

Abstract: PURPOSE:To prepare a polyhydric alcohol mainly arabitol, by cultivating a novel microorganism of the genus Brettanomyces in preparation of the polyhydric alcohol CONSTITUTION:A microorganism of the genus Brettanomyces, eg Brettanomyces sp SN-88 strain (FERM-P No7595), is cultivated in a culture medium containing a fermentable saccharide, eg glucose, as a main carbon source under aerobic conditions, and the aimed polyhydric alcohol accumulated in the culture fluid is separated and collected by the well-known means, filtration or ion exchange or adsorption chromatography, etc
