Herein, with the aid of ionic liquid, we demonstrate for the first time that highly stable Au/SiO2 hetero-nanocomposites can serve as a robust and recyclable peroxidase mimic for realizing high-temperature catalytic reactions. Our findings pave the way to use nanomaterials for the design and development of efficient biomimetic catalysts and, more significantly, to apply ionic liquid as a positive modulator in catalytic reactions.

The great challenges of modern industry and the environment make it important to develop sustainable energy resources with low cost. In this work, a cleaner enzymatic procedure for biodiesel production was developed through the utilization of a biocompatible and hydrophilic ionic liquid [Choline][H2PO4]. This ionic liquid can be synthesized from cheap raw materials through simple neutralization procedures, and it has been proved to be well biocompatible. The utilization of this ionic liquid in Novozym 435 catalyzed biodiesel production makes the reaction and work-up procedures very simple, because its hydrophilicity can lead to the implementation of a pseudo homogeneous reaction and then heterogeneous separation. Various oil resources such as triolein, sunflower oil and castor oil can all be converted to biodiesels with high yields. After the completion of reaction, both the ionic liquid and Novozym 435 can be recycled and reutilized for at least five cycles without a significant activity decrease. In addition, this reaction system can be conveniently scaled up to the multi-gram level with high efficiency and feasible separation. Overall, the above mentioned benefits make this ionic liquid based enzymatic system cleaner for the production of biodiesel and promising for further industrial applications.

PROBLEM TO BE SOLVED: To provide: a biocatalyst solvent that can be stored for a long period of time and that can dissolve a high concentration of a biocatalyst from low temperatures to high temperatures while retaining the activity of the biocatalyst; and a biocatalyst solution using the biocatalyst solvent. SOLUTION: The biocatalyst solvent is composed of an ionic liquid containing anions and quaternary ammonium cations represented by the following formula (1), where each Ra independently represents: a hydroxyalkyl group which has at least one hydroxyl group, in which the alkyl moiety is in a C1-10 straight-chained or branched state, and in which the alkyl moiety may contain an oxygen atom; a carboxyalkyl group which has at least one carboxy group, in which the alkyl moiety is in a C1-10 straight-chained or branched state, and in which the alkyl moiety may contain an oxygen atom; or a hydroxy-carboxyalkyl group which has at least one each of a hydroxyl group and a carboxy group, in which the alkyl moiety is in a C1-10 straight-chained or branched state, and in which the alkyl moiety may contain an oxygen atom and where each Rb independently represents a hydrogen atom or a C1-5 straight-chained or branched alkyl group. n represents an integer of 1-4.

A short, simple and inexpensive process for the extraction of DNA from meat was developed investigating a set of 20 ionic liquids including imidazolium, choline and guanidinium derivatives in combination with aqueous buffer systems. The environmentally benign ionic liquid choline hexanoate-phosphate buffer mixture gave the most promising results and DNA was extracted within 20 minutes from different types of meats, such as beef, chicken, pork and horse in significantly higher yields compared to the pure phosphate buffer. The influence of the ionic liquid on the amplification process during the PCR was further investigated, showing an inhibitory effect with increasing chain length of the ionic liquid and with higher ionic liquid concentrations. Additionally, extracted DNA was stable for 20 days when stored at room temperature in aqueous ionic liquid-buffer mixtures.
