“…Although it has been recently shown that p-coumaric acid also has some antimicrobial properties at the same concentrations used in this study (Lou et al 2012), the antimicrobial effect of p-coumaric acid in Bioscreen experiments was only seen on some strains and the effect being much weaker than those of RE or RO. Recent research of Zhao et al (Zhao et al 2015) also supports this finding. They found that p-coumaric acid exhibits low inhibitory activity against S. aureus, but no inhibitory effect on other tested bacteria, including E. coli, Listeria monocytogenes and Staphylococcus typhimurium.…”

Aims: The aim of this study was to examine the antimicrobial properties of novel aqueous natural rapeseed oil/saline emulsions containing different soluble components of spruce resin. Methods and Results: The composition of aqueous resin emulsions was analysed by GC-MS and their antimicrobial properties were studied with challenge tests and with turbidometric assays. The emulsions were strongly antimicrobial against common Gram-positive and Gram-negative bacteria (including MRSA) as well as common yeasts. Furthermore, they inhibited the biofilm formation and eradicated the microbial biofilms on tested microbes. Characteristic for the emulsions was the presence of oxidized resin acids. Other main components present in emulsions, such as lignans and coumaric acids, were not antimicrobial, when tested separately. Conclusions:The results indicated that the oxidized resin acids were the antimicrobial components in the emulsions. Also, there appears to be a stoichiometric relationship between the number of resin acid molecules and the number microbe cells in the antimicrobial action. Significance and Impact of the Study: The fact that these solutions do not contain abietic acid, which is the main allergenic compound in resins, suggests that these solutions would be suitable, well-tolerated antimicrobials for various medical applications. The aqueous formulation will also allow the expansion of the use of these emulsions in from medical applications to the food preservatives and disinfectants. IntroductionCreams or salves based on natural resins collected from trunks ("callus" resin) of Norway spruce (Picea abies), have been used as home-made remedies for skin wounds and infections for hundreds of years (Cowan 1999;Kalemba and Kunicka 2003;Mahady 2005;Rautio et al. 2007;Sipponen 2013). The water-insoluble main resin acids (e.g. abietic acids or dehydroabietic acid) in coniferous resins have been shown to be antimicrobial and antifungal in several previous studies (S€ oderberg et al. 1990;Savluchinske Feio et al. 1999;Rautio et al. 2007Rautio et al. , 2012Sipponen and Laitinen 2011). However, the poor solubility in water limits their applicability as microbicidal agents, or as modern liquid antiseptics (Peng and Roberts 2000;Keeling and Bohlmann 2006).A novel method to disperse the partially soluble components of natural coniferous resins into water makes the manufacturing of aqueous resin emulsions possible. However, this might lead to the loss antimicrobial properties due to the exclusion of resin acids. In this study, we examined the retained antimicrobial activities of two 136

“…The phenolic content of the bagasse extract was low at 0.5 mg g −1 , lower than 3.65 mg g −1 previously reported by Zheng et al (). These phenolic contents in bagasse are mostly present in cell walls and consist of gallic acid, ferulic acid, p ‐coumaric acid and vanillic acids (Xu et al , ; Zhao et al , ). In most HTL studies, pre‐treatment is targeted towards biofuel and phenolics from lignin lowers pH, inhibiting enzymatic hydrolysis so alkaline solvents are employed to maintain pH above 5.…”

Summary Bagasse, a by‐product from raw sugar factories, is conventionally burned for energy production. In this study, bagasse extracts from hydrothermal liquefaction (HTL) treatment (160 °C, 1 MPa and 30 min) with a carbohydrate content of 510.3 mg g−1 and 0.5 mg g−1 of total phenols were applied as emulsifiers in oil‐in‐water (O/W) emulsions. Bagasse extracts from HTL (0.5–4 wt%) lowered the interfacial tension between oil–water interphase from 19.8 to 14.0 mN m−1, owing possibly to the surface‐active hydrophilic carbohydrate‐hydrophobic lignin complexes in the extracts (lignin content: 7.1% w/w). Emulsions stabilised by bagasse extracts from HTL with average droplet size, dav of 0.79 μm were comparable with gum arabic (GA), dav of 2.24 μm after 11 days at 25 °C. Bagasse extracts containing biopolymers have the potential for industrial applications involving emulsion systems; therefore, HTL treatment of bagasse without any solvents can be regarded as an effective tool for producing natural emulsifiers.

“…Sugarcane bagasse is another example. Bagasse contains many compounds of potential value, including polyphenols which must be extracted at conditions which minimize thermal degradation (Zhao et al, 2015). In contrast, temperatures as great as 190°C can be used for the extraction of non-cellulosic heteropolysaccharides composed of xylose, glucose, galactose, mannose, arabinose, and smaller amounts of 4-O-methylglucuronic acid compared with sugarcane.…”

This review summarizes the recent essential aspects of subcritical and supercritical water technology applied to the extraction, hydrolysis, carbonization, and gasification processes. These are clean and fast technologies which do not need pretreatment, require less reaction time, generate less corrosion and residues, do not use toxic solvents, and reduce the synthesis of degradation byproducts. The equipment design, process parameters, and types of biomass used for subcritical and supercritical water process are presented. The benefits of catalysis to improve process efficiency are addressed. Bioactive compounds, reducing sugars, hydrogen, biodiesel, and hydrothermal char are the final products of subcritical and supercritical water processes. The present review also revisits advances of the research trends in the development of subcritical and supercritical water process technologies. GRAPHICAL ABSTRACT ARTICLE INFO ABSTRACT
