Phytochemicals in bioenergy crops

The use of natural compounds derived from agricultural crops and other plants as health promoting chemicals gains tremendous growing interest in various industrial sectors as well as among people worldwide. These chemicals have been more and more employed by the food industry as food additives, functional food ingredients, nutraceuticals, by feedstuffs industry, but also by the cosmetic and pharmaceutical industries. The general idea for this interest is to use natural products as potential alternatives to synthetic chemicals. On the other hand, some plants characterized by high yield and being used as energy crops also contained significant amount of bioactive compounds. This review focuses on the wide spectrum of the phytochemicals present in available biomass plants. It is supposed that extraction of bioactive chemicals from energy crops before their energetic use may increase economical effectiveness, providing simultaneously a double benefit in the form of phytochemicals and bioenergy as value added products. This remains in line with bioeconomy, which is defined by European Commission as ''the production of renewable biological resources and the conversion of these resources and waste streams into value added products, such as food, feed, bio-based products and bioenergy''. However, the issue is still a challenging effort due to the high costs, technology readiness and regulatory hurdles.

“…Additionally, trigonelline works as a signal transmitter in diverse processes such as circadian rhythm, nodulation and oxidative stress [20]. It is noteworthy that trigonelline-as a ubiquitous osmolyte-helps plants to challenge abiotic stress by sustaining turgor pressure, protecting the integrity of the plasma membrane and stabilizing the structure and function of proteins [17,26,27]. However, a fine-tuned regulatory mechanism of trigonelline in response to abiotic stress lacks definitive evidence at the molecular level.…”

Areca catechu L. is a commercially important palm tree widely cultured in tropical and subtropical areas. Its growth and production are severely hindered by the increasing threat of drought. In the present study, we investigated the physiological responses of areca seedlings to drought stress. The results showed that prolonged drought-induced yellowing on the overall area of most leaves significantly altered the chlorophyll fluorescence parameters, including maximum chemical efficiency (Fv/Fm), photochemical efficiency of PSII (Y(II)), photochemical chlorophyll fluorescence quenching (qP) and non-photochemical chlorophyll fluorescence quenching (NPQ). On the 10th day of drought treatment, the contents of proline in the areca leaves and roots increased, respectively, by 12.2 times and 8.4 times compared to normal watering. The trigonelline levels in the leaves rose from 695.35 µg/g to 1125.21 µg/g under 10 days of water shortage, while no significant changes were detected in the content of trigonelline in the roots. We determined the gene encoding areca trigonelline synthase (AcTS) by conducting a bioinformatic search of the areca genome database. Sequence analysis revealed that AcTS is highly homologous to the trigonelline synthases in Coffea arabica (CaTS 1 and CaTS 2) and all possess a conserved S-adenosyl- L-methionine binding motif. The overexpression of AcTS in Arabidopsis thaliana demonstrated that AcTS is responsible for the generation of trigonelline in transgenic Arabidopsis, which in turn improves the drought resilience of transgenic Arabidopsis. This finding enriches our understanding of the molecular regulatory mechanism of the response of areca to water shortage and provides a foundation for improving the drought tolerance of areca seedlings.

“…Quaternary ammonium salts (QASs), commonly found in nature (Anthoni et al 1991;Giri 2011;Schwartz et al 2014), are synthesized by organisms for better fitness to changes in environmental conditions such as the salinity or temperature. QASs are also involved in the transport and metabolism of lipids (Smith et al 1988;McGregor et al 2001;Chen and Murata 2011;Giri 2011).…”

Quaternary ammonium salts (QASs) are commonly used in medicine, agriculture and industry and their wide usage caused the development of microbial resistance, thus there is still a need for new effective antimicrobial agents. Present work describes the biological activity of alanine‐ (DMALM‐n) and glycine‐derived (DMGM‐n) QASs against planktonic and biofilm forms of micro‐organisms. The antimicrobial activity was dependent mainly on the hydrocarbon chain length and surfactants with 12–16 atoms of carbon in the alkyl chain were the most active ones. The lowest MIC value was determined for DMALM‐14 against Rhodotorula rubra and Saccharomyces cerevisiae (2·5 µmol l−1). Generally, alanine derivatives showed stronger effects against micro‐organisms than glycine‐derived QASs. Alanine‐derived surfactants with 12–16 carbons in the alkyl chain had antiadhesive properties on the polystyrene surface, preventing cell attachment (about 70% of inhibition for C. albicans and 40% for S. epidermidis). Strong adhesion reduction was also observed on the stainless steel surface and the highest reduction was observed for C. albicans cells incubated on surface pretreated with DMGM‐16. Moreover, DMGM‐16 and DMALM‐16 prevented C. albicans filamentation, one of the determinants of cell adhesion. Surfactants with C16 alkyl chain (DMGM‐16 and DMALM‐16) eradicated bacterial and yeast biofilm (from 60 to 90% of reduction observed after incubation of the previously grown biofilm in the presence of the highest tested concentration of the surfactant – 400 µmol l−1) and reduced its viability. Strong antimicrobial activity as well as antiadhesive properties make alanine‐ and glycine‐derived QASs the potential candidates for future application as disinfectants. Significance and Impact of the Study Cationic surfactants are used in many fields, among others in medicine, cosmetic and pharmaceutical industry. Their usage on a large scale caused the development of microbial resistance mechanisms to such compounds. Thus, there is a need to synthesize new surfactants with potential application as effective disinfectants to combat both planktonic and biofilm forms of micro‐organisms. Present work focuses on the antimicrobial activity of chosen quaternary ammonium salts.
