1. Vinegar rice (Oryza sativa L.) produced by a submerged fermentation process from alcoholic fermented rice
Considering the limited availability of technology for the production of rice vinegar and also due to the potential consumer product market, this study aimed to use alcoholic fermented rice (rice wine (Oryza sativa L.)) for vinegar production. An alcoholic solution with 6.28% (w/v) ethanol was oxidized by a submerged fermentation process to produce vinegar.

2. Pathway analysis of the main organic and inorganic constituents affecting the color of the juice in sugarcane cultivars / Análise de trilha dos principais constituintes orgânicos e inorgânicos sobre a cor do caldo em cultivares de cana-de- açúcar
Brazil is the main producer and exporter of sugar in the world. For 2008, its production is estimated to reach more than thirty million tons. One requirement for exportation of the sugar is its coloration, that must be in accordance with the International Commission for Uniform Methods in Sugar Analysis - ICUMSA. The color ICUMSA (sugar) can also be applied

3. Aplicação de vinhaça e do extrato de palhiço de cana-de-açúcar no controle de plantas daninhas / Use of vinasse and sugarcane straw extract on weed control
Sugarcane (Saccharum officinarum L.) has major presence in the history of Brazil and possess great expression in the current national economy. The objective of this work was to determine the occurrence effects of vinasse and raw extract of sugarcane in the control of weeds. The experiments were carried out in greenhouse. Treatments used were vinasse at 0, 10

4. Transport of Tricarboxylic Acids in Salmonella typhimurium
Salmonella typhimurium possesses at least three inducible transport systems for the tricarboxylic acids (citric, isocitric, cis-aconitic, and tricarballylic). The first system was induced by citrate, isocitrate, or cis-aconitate, and transported citric acid and isocitric acid. The second system was also induced by the same acids as in the first system and tr

6. Organic Acids and Iron Translocation in Maize Genotypes
Translocation of Fe was studied in WF9 (Fe-efficient) and ys1/ys1 (Fe-inefficient) maize (Zea mays L.) genotypes. Iron-deficient WF9 translocated more Fe to the tops than Fe-deficient ys1/ys1. Malate and citrate contents of root saps increased nearly 2-fold and aconitate increased over 4-fold in both genotypes as Fe of nutrient solutions increased from 0.1 t

7. Experimental visceral leishmaniasis: role of trans-aconitic acid in combined chemotherapy.
We previously reported the effectiveness of trans-aconitic acid (TAA) as an antileishmanial compound. Inhibitory effects of TAA along with other antileishmanial compounds on transformation and in vitro multiplication in macrophage cultures of Leishmania donovani have been assessed. The efficacy of TAA in combined chemotherapy of experimental visceral leishma

8. Metabolism of trans-Aconitic Acid in Maize 1: I. PURIFICATION OF TWO MOLECULAR FORMS OF CITRATE DEHYDRASE
Trans-aconitate synthesis via citrate dehydrase was determined in crude extracts of maize (Zea mays L.) coleoptiles. Two molecular forms of this enzyme were purified by substrate-specific elution from DEAE-cellulose, ammonium sulfate precipitation, and gel filtration. Each molecular form migrates as a single band in isoelectric focusing. Gel filtration and s

9. Low- and high-affinity transport systems for citric acid in the yeast Candida utilis.
Citric acid-grown cells of the yeast Candida utilis induced two transport systems for citric acid, presumably a proton symport and a facilitated diffusion system for the charged and the undissociated forms of the acid, respectively. Both systems could be observed simultaneously when the transport was measured at 25 degrees C with labelled citric acid at pH 3

10. Enrichment and Isolation of Rumen Bacteria That Reduce trans- Aconitic Acid to Tricarballylic Acid
Bacteria from the bovine rumen capable of reducing trans-aconitate to tricarballylate were enriched in an anaerobic chemostat containing rumen fluid medium and aconitate. After 9 days at a dilution rate of 0.07 h−1, the medium was diluted and plated in an anaerobic glove box. Three types of isolates were obtained from the plates (a crescent-shaped organism

11. Massive targeting of liposomes, surface-modified with anionized albumins, to hepatic endothelial cells
Human serum albumin (HSA) derivatized with cis-aconitic anhydride was covalently coupled to liposomes with a size of approximately 100 nm [polyaconitylated HSA (Aco-HSA) liposomes]. Within 30 min after injection into a rat, Aco-HSA liposomes were completely cleared from the blood and almost exclusively taken up by the liver, whereas in control liposomes 80%

12. Identification of 1,4-Benzoxazin-3-ones in Maize Extracts by Gas-Liquid Chromatography and Mass Spectrometry 1
Gas-liquid chromatography-mass spectrometry (GLC-MS) has been used for the separation, detection, and identification of 1,4-benzoxazin-3-ones (hydroxamic acids and lactams) and benzoxazolinones found in maize (Zea mays L.) extracts. Compounds of interest were partitioned into ethyl acetate from aqueous maize seedling extracts. For analysis by GLC-MS, trimeth
