Different relative humidity conditions combined with chloride and sulfate salinity treatments modify abscisic acid and salicylic acid levels in the halophyte Prosopis strombulifera
It has been shown that abscisic acid (ABA) and salicylic acid (SA) act as endogenous signal molecules responsible for inducing abiotic stress tolerance in plants. However, our knowledge on the role of both phytohormones ...
Enhancement of polyunsaturated fatty acid production under low-temperature stress in Cylindrotheca closterium
Marine microalgae synthetize great amounts of essential metabolites such as fatty acids and amino acids. In addition, their exposure to stress factors can induce the overproduction of these desirable metabolites. Thus, in ...
Influence of the operating conditions on acid degumming process in sunflower seed oil
We have now extended this study, investigating the effect of dif-ferent variables related mainly to the acid refining step (typeand concentration of degumming agents, temperature andcontact time), in accordance with ...
Physicochemical and technological properties of soybean as a function of storage conditions
(Universidade Tecnológica Federal do Paraná (UTFPR), 2016)
Bile acids: Lipase-catalyzed synthesis of new hyodeoxycholic acid derivatives
(Elsevier Science Inc, 2018-12)
In this work we present an efficient, environmentally friendly approach to the synthesis of a series of hyodeoxycholic acid derivatives applying Biocatalysis. Fifteen acetyl and ester derivatives, twelve of them new, were ...
Production of biodiesel from acid oil using sulfuric acid as catalyst: Kinetics study
(Oxford University Press, 2011-03)
Biodiesel production is becoming more relevant due to its environmental advantages together with the global petroleum situation regarding decreases of the reserves, instability of the prices and so on. The kinetics of the ...
Proteomic Analysis of Rhizobium favelukesii LPU83 in Response to Acid Stress
(American Chemical Society, 2019-08-21)
Acid soils constitute a severe problem for leguminous crops mainly through a disturbance in rhizobium-legume interactions. Rhizobium favelukesii - an acid-tolerant rhizobium able to nodulate alfalfa - is highly competitive ...
Influence of trans fatty acids on glucose metabolism in soleus muscle of rats fed diets enriched in or deprived of linoleic acid
(Dr Dietrich Steinkopff Verlag, 2018-06)
Purpose: Industrial trans fatty acid (TFA) intake leads to impaired glucose metabolism. However, the overall effects reported are inconsistent and vary with the dietary FA composition and TFA isomer type and levels. We ...
Selective hydrogenation of oleic acid to fatty alcohols over a Rh-Sn-B/Al2O3catalyst: Kinetics and optimal reaction conditions
(Royal Society of Chemistry, 2021-04)
The selective hydrogenation of oleic acid to oleyl alcohol over a Rh(1 wt%)-Sn(4 wt%)-B/Al2O3 catalyst was studied. A comprehensive set of experimental data was used for elucidating the reaction mechanism. In the range of ...
Free α-amino acids, γ-Aminobutyric acid (GABA), phenolic compounds and their relationships with antioxidant properties of sorghum malted in different conditions
(Association of Food Scientists and Technologists of India, 2018-08)
Two cultivars of sorghum were germinated at 25 or 30 °C for 1, 2, or 3 days to investigate the evolution of γ-Aminobutyric acid (GABA), total free phenolic compounds (FPC), hydroxycinnamic acid derivatives, free amino acid ...
