AbstractChanges in the ultrastructure and chemical components, and their distribution in Japanese beech (Fagus crenata), during the ionic liquid 1-ethylpyridinium bromide ([EtPy][Br]) treatment were examined at the cellular level by light microscopy, scanning electron microscopy, and confocal Raman microscopy. Each of the tissues, including wood fibers, vessels and parenchyma cells treated with [EtPy][Br] showed specific morphological characteristics. Furthermore, lignin can be preferentially liquefied and eluted in [EtPy][Br] from the cell walls when compared to polysaccharides. However, the delignification was heterogeneous on the cell walls as lignin maintained a relatively high-concentration at the compound middle lamella, cell corners, inner surface of the secondary wall, and pits after [EtPy][Br] treatment.

Ancient Times

Schiff bases were often used as chelating ligands for the stabilization of metal ions with various oxidation states. It is called privileged ligands, due to their own peculiar capacity to make a four and six coordinated salen complex to stabilize the metal ions. On the other hand, Ionic liquid (IL) also plays a key material in engineering and scientific fields. Due to their own physiochemical properties and widespread applications in different areas of research. It has been recently found that, the suitable choice and appropriate size of cation and anion can alter the geometry of ILs and it directly influenced the biological activity of ILs. Herein ionic liquid tagged new salen complexes of first row transition metals such as Fe, Co, Ni, Cu and Zn have been synthesized successfully and characterized. The structure of synthesized salen complexes were studied by UV, FT-IR, NMR and Mass spectroscopic techniques. Metal complexes play a vital role in drug discovery since ancient times. Especially, these complexes can interact with the cell membrane and make the morphological changes in the affected site. Moreover, the efficiency of salen complexes were assessed by antimicrobial and antifungal studies. Among all the IL tagged salen complexes the Ionic liquid tagged cobalt salen complexes was very effective against the tested microorganisms.

In this work, different kinds of ionic liquids and reaction conditions for the extraction of lipid from microalgae biomass were optimized and repeated use of ionic liquids for microalgal lipid extraction was evaluated. Morphological changes of microalgae cells were compared in terms of pre- and post-treatment to understand the mechanisms of ionic liquid treatment. Ionic liquid [BMIM][MeSO4] showed the best lipid extraction efficiency at 70°C and with reaction time of 2 hours. The ratios (ILs : methanol) of 1 : 7 and 1 : 3 were the optimum ratios to complete the extraction of the lipids from microalgae. The initial 50% volume fraction of [BMIM][MeSO4] was 16.04% of dry weight, which showed the highest five average extraction rates. The loss of ionic liquid in the reaction system and the increase in water content of ionic liquids were considered as the main reasons for the decrease in the extraction rate. It is suggested that the potential of lipid extraction in this IL-methanol co-solvent system is promising due to the high efficiency, low cost, safety, environmental protection, and other characteristics.
