Cost-effective production of bioethanol from waste material is becoming the need of the hour to combat the exhaustive nature of fossil fuel. In this study, bioethanol was produced from microwave-pretreated kitchen waste at high dry material consistency. Pretreatment was performed for 30 min at a constant power of 90 W. Liquefaction/saccharification was done with in-house produced amylase from Bacillus licheniformis MTCC 1483. The liquefaction step was optimized using response surface modeling. Three factors, viz. pH, concentration of dry substrate and amylase, were optimized by using reducing sugar and ethanol yield as response. The optimum conditions of input parameters obtained were pH 7.5, dry material 40% (w/v) and amylase 15 IU g −1. The process developed in the present study leads to 0.129 g ml −1 , i.e., 0.32 g per g biomass ethanol production. The novelty of the manuscript lies in the fact that no acid/alkali hydrolysis was carried out for the release of reducing sugar. Instead, microwave treatment was carried out at low power for longer time so as to release maximum sugar. The cost incurred in bioethanol production was also estimated by taking cost of chemicals, instruments and operating cost in account. The total cost of bioethanol produced in the present study was calculated as 0.143 $/l of ethanol. A 8.32-fold decrease in price of ethanol produced in the present study was observed when compared to the market selling price of ethanol. This makes the developed process economically and industrially feasible.

Canna edulis Ker-Gawl is a versatile crop that integrates food, energy, and feed in China. The rhizome is a traditional Chinese medicine with a long history. However, there are few studies on chemical components. Crude plant extracts are a complex mixture of several biologically active secondary metabolites. Therefore, rapid and accurate identification and quantification are critical in phytochemical analysis. An efficient approach based on ultrahigh-performance liquid chromatography coupled with Q-Exactive Orbitrap tandem mass spectrometry (UHPLC Q-Exactive Orbitrap MS) was used to analyze the chemical components systematically. We used retention time, accurate molecular weight, parent peaks, fragment peaks, fragmentation characteristics, comparative analysis with the literature, reference standards, and standard databases, including ChemSpider, mzVault, MassBank, and mzCloud. A total of 54 chemical constituents were identified from the methanol extract of the rhizome, including 36 organic acids (with six phenolic acids), three phenols, one sugar (and its derivatives), one coumarin, one triterpenoid, ten N-containing organic compounds (including seven amino acids), and two other compounds. Moreover, three compounds were quantitatively analyzed and a methodological study of the three components was carried out. The established method provided satisfactory precision and accuracy, acceptable recovery, good linearity, and a reasonable detection limit. The UHPLC Q-Exactive Orbitrap MS method was used for the first time to accurately, quickly, and systematically characterize the compounds of the rhizome, revealing the pharmacodynamic substances and providing a theoretical basis for its quality control, in-depth research, and development.
