Potato plants (Solanum tuberosum L. cv. Bintje) were grown in open-top chambers (OTCs) under three CO(2) levels (ambient and 24 h d(-1) seasonal mean concentrations of 550 and 680 micromol mol(-1)) and two O(3) levels (ambient and a seasonal mean 8 h d(-1) concentration of 50 nmol mol(-1)). The
Algal cultivation for converting cull potato to docosahexaenoic acid (DHA) was studied. Schizochytrium limacinum SR21 was selected as the better producing strain, compared with Thraustochytrium aureum because of higher cell density and DHA content. Used as both carbon and nitrogen source, an optimal
In this work, we developed a novel approach combining bioinformatics, testing of functionality and bottom-up proteomics to obtain peptide emulsifiers from potato side-streams. This is a significant advancement in the process to obtain emulsifier peptides and it is applicable to any type of protein.
This paper presents Q-band electron spin resonance (ESR) studies on free radicals (FR) generated in potato leaves exposed to different O(3) levels in open-top chambers (OTC), together with a quantitative study of the relationship between FR signal intensity and area of potato leaf damage. The
The antigenic properties of capsid proteins of potato virus Y (PVY) strains have been studied, the most wide antigenic specificity of necrotic group strains has been marked. Several antigen-active strains of necrotic group strains (PVY-N Far East, PVY-N Leningrad, PVY-N Moscow) and common group
Aspergillus oryzae alpha-amylase [(1----4)-alpha-D-glucan glucanohydrolase, EC 3.2.1.1] produced O-(6-phosphoryl-alpha-D-glucopyranosyl)-(1----4)-O-alpha-D-glucopyran osy l-(1----4)-D-glucopyranose (6(3)-phosphorylmaltotriose) and
A simple, sensitive, and selective high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method in the negative-ion electrospray ionization (ESI(-)) mode was validated for the quantitation of bromate (BrO(3)(-)) in potato snacks. Ground snack specimens ( approximately 0.5
Potato starch propargyl ethers (PgS) with degrees of substitution (DS) from 0.1 to 2.2 have been prepared by etherification of starch with sodium hydroxide or Li dimsyl in Me(2)SO and propargyl bromide. DS values and substituent distribution were determined after hydrolysis and acetylation by GC-MS.
Sweet potato starch was cross-linked using sodium trimetaphosphate and hydroxypropylated using propylene oxide. The level and position of phosphorus and hydroxypropyl groups within cross-linked and hydroxypropylated sweet potato starch was investigated by phosphorus and proton nuclear magnetic
An arabinogalactan-protein (WSSP-AGP) was isolated from the tuberous cortex of the white-skinned sweet potato (WSSP; Ipomoea batatas L.). It consists of 95% (w/w) carbohydrate and 5% (w/w) protein with high contents of hydroxyproline, alanine, and serine. Its sugar composition is
Six potato cultivars were grown to maturity in field plots in New Brunswick, New Jersey, according to standard commercial practices over a 5-year period. One-half of the plots were given a periodic soil drench of an antioxidant (EDU) which has the capacity to protect foliage against ozone toxicity.
An open-top chamber experiment with field grown potato (Solanum tuberosum L. cv. Bintje) was performed in the south-west of Sweden in 1998. The experiment was aimed to investigate individual and interactive impacts of elevated ozone (O(3)) and carbon dioxide (CO(2)) on potato growth and yield.
BACKGROUND
In addition to the actual composition of the diet (i.e. nutrient composition, food groups), the omega-6/omega-3 fatty acid ratio has been demonstrated to influence the tissue fatty acid profile and subsequently the risk for cardiovascular and other diseases. Likewise, the consumption of
The effect of ozone (O(3)) on ribulose bisphosphate carboxylase/oxygenase (Rubisco) activity and quantity and net photosynthesis in greenhouse-grown Solanum tuberosum L. cv ;Norland' foliage was studied in relation to oxidant-induced premature senescence. Plants, 26 days old, were exposed to 0.06 to
Acetylated trigalacturonides and rhamnogalacturonan I (RG-I)-derived oligosaccharides were isolated from a Driselase digest of potato tuber cell walls by ion-exchange and size-exclusion chromatography. The oligosaccharides were structurally characterized by fast atom bombardment-mass spectroscopy,
