“…Soybean is an oleaginous plant with a large capacity to produce grains rich in proteins (Bamji and Corbitt 2017). Soybean are important to human and animal nutrition and are a major source of energy in biofuels (Abdulkhani et al 2017). Currently, soybean is the most cultivated and consumed legume in the world (Thilakarathna and Raizada 2017) with approximately 314 million tons produced in the 2015/2016 harvest (FAO 2017).…”

Drought frequently results in significant losses in agricultural systems, including the soybean yield. Brassinosteroids exhibit multiple actions on essential processes, including chlorophyll fluorescence and gas exchange. Considering that the electron transport rate (ETR) into photosystems can exercise interference on net photosynthetic rate (PN), this research aims to determine whether 24-epibrassinolide (EBR) affects electron transport and find out if there is any repercussion on photosynthesis in soybean plants affected by the water deficit. The experiment was performed using a randomized factorial design, with two water conditions (control and water deficit) and three EBR concentrations (0, 50, and 100 nM EBR). The water deficit reduced effective quantum yield of PSII photochemistry, ETR, PN, and water-use efficiency. However, the exogenous application of 100 nM EBR mitigated these negative effects, increasing these variables. EBR reduced the oxidant compounds (superoxide and hydrogen peroxide) and membrane damages (malondialdehyde and electrolyte leakage) in stressed plants. Our study proved that EBR increased ETR and PN in control and stressed plants, revealing that ETR had a strong relationship with PN. These results suggest that soybean plants with higher values of ETR are more efficient in relation to PN.Additional key words: chlorophyll fluorescence; drought; gas exchange; Glycine max; 24-epibrassinolide. transport rate; ETR/PN -ratio between the apparent electron-transport rate and net photosynthetic rate; EXC -relative energy excess at the PSII level; F0 -minimal fluorescence yield of the dark-adapted state; Fm -maximal fluorescence yield of the dark-adapted state; Fv -variable fluorescence; Fv/Fm -maximal quantum yield of PSII photochemistry; gs -stomatal conductance to water vapor; LDM -leaf dry matter; MDA -malondialdehyde; NPQ -nonphotochemical quenching; PEG -polyethylene glycol; PN -net photosynthetic rate; PN/Ci -instantaneous carboxylation efficiency; qP -photochemical quenching; RDM -root dry matter; ROS -reactive oxygen species; STM -stem dry matter; TDM -total dry matter; WUE -water-use efficiency; ΦPSII -effective quantum yield of PSII photochemistry.

“…For biodiesel production, the use of oleaginous plants is usual, along with others, such as animal fats, fried oils, algae, bacteria, etc., and many research works about its production and performance in engines or tribology were carried out, which points out the importance that biodiesel has been gaining recently [10][11][12][13][14][15][16][17][18]. In the case of vegetable oils, such as canola, rapeseed, soya, or safflower oils, among others, they have been considered to produce biodiesel [7,[19][20][21][22], with acceptable results.…”

Safflower Biodiesel: Improvement of its Oxidative Stability by Using BHA and TBHQ

2019

Biodiesel is gaining more and more importance due to environmental issues. This way, alternative and sustainable crops as new biofuel sources are demanded. Safflower could be a sustainable raw material for biodiesel production, showing one disadvantage (as many biodiesels from vegetable oils), that is, a short oxidative stability. Consequently, the use of antioxidants to increase this parameter is mandatory. The aim of this research work was to assess the effect of two antioxidants (butylated hydroxyanisole, BHA, and tert-butylhydroquinone, TBHQ) on the oxidative stability of safflower biodiesel, which was characterized paying attention to its fatty acid methyl ester profile. For oxidative stability, the Rancimat method was used, whereas for fatty acid profile gas chromatography was selected. For the remaining parameters, the methods were followed according to the UNE-EN 14214 standard. The overall conclusion was that safflower biodiesel could comply with the standard, thanks to the use of antioxidants, with TBHQ being more effective than BHA. On the other hand, the combined use of these antioxidants did not show, especially at low concentrations, a synergic or additive effect, which makes the mixture of these antioxidants unsuitable to improve the oxidative stability.

“…Global soybean production in 2016 was 324 million tons, a significant increase of 17% compared to 2013. The United States, Brazil, and Argentina are the largest soybean producers in the world, with a production that occupies more than 80% of the world production of this oilseed [5]. Brazil is the country with the greatest potential for expansion of the cultivated area, being the largest producer and exporter of soybeans and their derivatives worldwide.…”

Biorefinery Concepts, Energy and Products

The concept of biorefinery is analogous to that of petroleum refineries, but it uses renewable raw materials. However, the main objective of the biorefinery is to transform renewable agricultural materials into numerous and different commercially applicable products, allowing a viable economic competitiveness to traditional petrochemical refineries. In this chapter, we present a proposal for a biorefinery integrated from soybean as raw material, demonstrating its potential in this sector. In addition, special focus was given to the high value-added products present in the soybean oil deodorizer distillate (SODD), such as tocopherol, fatty acids, and squalene, which can be applied in the food, pharmacy, and cosmetic industries. In conclusion, the use of soybean raw material as a biomass in a biorefinery presents numerous environmental and economic advantages as high value-added products are formed. It is important to highlight that in this highly evolved integrated biorefinery model, the additional benefits of operational and administrative synergies will emerge over time.
