Última Effect of malate on docosahexaenoic acid production from Schizochytrium sp. B4D1 Electron. J. Biotechnol. Zhanga,Yong; Min,Qingsong; Xu,Jian; Zhang,Ke; Chen,Shulin; Wang,Haijun; Li,Demao. Background: Malate involves in the citrate/malate and transhydrogenase cycles to provide precursors for docosahexaenoic acid (DHA) synthesis. The optimal strategy was investigated for increasing DHA production in Schizochytrium species during fermentation. Results: DHA production increased by 47% and reached 5.51 g/L when 4 g malate/L was added during the rapid lipid accumulation stage in shake-flasks culture. Inducing effects of malate was further investigated through the analysis of three kinetic parameters, including specificcell growth rate(μ), specific glucose consumption rate (qGlu)and DHA formation rate (qDHA). DHA concentration was enhanced through a novel fed-batch strategy to a maximum value of 30.7 g/L, giving a yield of 0.103 g DHA/g...

Fisiol. Veg. MACÊDO,CRISTIANE ELIZABETH COSTA DE; KINET,JEAN MARIE; LUTTS,STANLEY. Citric and malic acid excretion in the medium and malic acid accumulation in seedling roots and embryo-derived calli as possible mechanisms of aluminum (Al) resistance and the effects of a 17-h Al stress period on root growth in Oryza sativa have been studied. Four-day-old seedlings and embryo-derived calli of Al-resistant (IRAT 112 and IR6023) and Al-sensitive (Aiwu and IKP) cultivars were treated with 250 and 500 µM {Al2(S04)3.18H20 }of total aluminum or without Al for 36 hours. After 3 to 36 hours of stress, seedlings and calli were removed from the flasks and concentration of citric and malic acids was estimated in the Al and control solutions. Malic acid was also assayed in roots tips and in callus tissues. After 17-h of Al stress, inhibition of root...

Pigna,Massimo; Jara,Alejandra A; Mora,María de la Luz; Violante,Antonio. The sulfate sorption was studied on Andisols with variable mineralogical composition and low organic matter content in presence and absence of phosphate or malate ligands at different pH. Crystalline clay mineralogy was similar for all the studied samples, except for the 2C horizon of the pedon 2, which did not show crystalline minerals. The soil samples showed content of allophane ranging from 16% to 42%. The sulfate adsorption decreased when descending the first 3 horizons (A1, 2A2 and 3Bw1) of the pedon 1. This behavior was attributed to the decreasing organic carbon content. At different pH sulfate sorption was drastically decreased by increasing the pH from 4.0 to 7.0, precisely by 80% for sample 5 to 100% for sample 1. Experiments on the competitive...
