Abstract
The objective of this paper is to gain insights into the synergistic advantage of anaerobic co-fermentation of heat-treated sludge (HS) with food waste (FW) and heat-treated food waste (HFW) for hydrogen production. The results showed that, compared with raw sludge (RS) mixed with FW (RS-FW), the co-substrate of HS mixed with either FW (HS-FW) or HFW (HS-HFW) effectively promoted hydrogen production, with HS-HFW promoted more than HS-FW. The maximum specific hydrogen production (MSHP) and the maximum hydrogen concentration (MHC) of HS-HFW were 40.53 mL H2/g dry weight and 57.22%, respectively, and 1.21- and 1.45-fold as high as those from HS-FW. The corresponding fermentation was ethanol type for HS-HFW and butyric acid type for HS-FW. The net energy production from RS-FW and HS-FW was both negative, but it was positive (2.57 MJ) from 40% HFW addition to HS-HFW. Anaerobic fermentation was more viable for HS-HFW.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:4853-4865. [PMID: 35974282 DOI: 10.1007/s11356-022-22443-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Accepted: 08/04/2022] [Indexed: 06/18/2023]
Abstract
Recycling organic waste and converting them into renewable energy are a promising route for environment protection and effective biochemical reactions suitable for industrial hydrogen synthesis. This study targeted to isolate a pure anaerobic culture with potential to hydrolyze different biomass and production of biohydrogen. For this, a sample of full-scale anaerobic digester, fed with a multicomponent solid, was inoculated on Reinforced Clostridial Medium (RCM) in strict anaerobic conditions. An anaerobic Clostridium butyricum CBT-1 strain was isolated, identified from morphological and 16S rRNA sequence. The CBT-1 culture expressed amylase, cellulase and peroxidases activities. The strain exhibited visual decolorization of both Azure B and crystal violet dyes. In batch fermentation experiment, the CBT-1 produced highest of 3.06, 2.67 and 2.46 mol/mol H2 yield from glucose, starch and cellulose respectively, whereas, the CBT-1 showed low 0.43 mol H2/mol of substrate from untreated rice straw due to lignin in compact structure and comparatively high H2 yield of 1.91 and 2.01 mol H2/mol of substrate rice straw hydrolysate and kitchen food waste (KFWS) respectively. The cumulative volumetric yield of H2 was 358.15, 300.8 and 294.5NmL/gSub from glucose, starch and cellulose respectively. Similarly, the cumulative H2 volume was 76.7, 184.4, 237.2 NmL/gVS from untreated rice straw, rice straw hydrolysate and kitchen food waste. This study emphasizes the prospects to find similar robust anaerobic culture for hydrolyzing complex biomass. Such strains could be used as standard co-inoculum for biohydrogen obtaining and as the biocatalyst for commercial scale applications.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2018; 25:24600-24610. [PMID: 30014369 DOI: 10.1007/s11356-018-2598-6] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/20/2018] [Accepted: 06/18/2018] [Indexed: 05/15/2023]
Abstract
The unregulated discharge reams of food waste (FW) causes severe resource loss and environmental pollution. In the present study, a bibliometric analysis was used for research activities and tendencies of food waste from 1991 to 2015. The results indicated that the amount of FW research continually grew by the years, and the number of publications rose significantly from 2012. Bioresource Technology and Waste Management were the two most frequently published journals in the field of FW research. China took a leading position and had a high h-index (38) out of 94 countries/territories, followed by the USA and South Korea. Presently, anaerobic digestion for methane and dark fermentation for hydrogen production are the mainstream techniques in FW disposal. Lactic and ethanol fermentation from FW received more and more attention in recent years. Life cycle assessment (LCA) was an ever-increasingly popular evaluation method for FW-related research. Moreover, cluster analysis indicated microbial community structure, food security, leachate, and pathogens were also the research hotspots.
