Abstract
Plastic waste is a growing global pollutant. Plastic degradation by microorganisms has captured attention as an earth-friendly tactic. Although the mechanisms of plastic degradation by bacteria, fungi, and algae have been explored over the past decade, a large knowledge gap still exists regarding the identification, sorting, and cultivation of efficient plastic degraders, primarily because of their uncultivability. Advances in sequencing techniques and bioinformatics have enabled the identification of microbial degraders and related enzymes and genes involved in plastic biodegradation. In this review, we provide an outline of the situation of plastic degradation and summarize the methods for effective microbial identification using multidisciplinary techniques such as multiomics, meta-analysis, and spectroscopy. This review introduces new strategies for controlling plastic pollution in an environmentally friendly manner. Using this information, highly efficient and colonizing plastic degraders can be mined via targeted sorting and cultivation. In addition, based on the recognized rules and plastic degraders, we can perform an in-depth analysis of the associated degradation mechanism, metabolic features, and interactions.

Abstract
This study has two targets: Studying the extraction of the initial protein content from brewer's spent grain and the impact of protein's extraction on the chemical-physical properties of produced hydrochars. The protein was extracted from brewer's spent grains using the pH-shifting method. The extracted protein was quantified and characterized by their amino acid profile. The hydrothermal treatment was applied at 190 °C and 220 °C for 0.5 h, 1 h, 2 h, and 4 h. The hydrochars and process water were collected and assayed. The hydrochar after protein extraction reveals the lowest yield to hydrochars (67.10-45.14%), higher C/N ratio (19.66-21.33) and lower ash content (1.52-1.72 wt%) compared to the hydrochar without extraction.

[PMID: 28672690 DOI: 10.1016/j.chemosphere.2017.06.095] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2016] [Revised: 05/21/2017] [Accepted: 06/22/2017] [Indexed: 06/07/2023]
Abstract
This study aimed to produce a high-value platform chemical, hydroxymethylfurfural (HMF), from food waste and evaluate the catalytic performance of trivalent and tetravalent metals such as AlCl3, CrCl3, FeCl3, Zr(O)Cl2, and SnCl4 for one-pot conversion. Starchy food waste, e.g., cooked rice and penne produced 4.0-8.1 wt% HMF and 46.0-64.8 wt% glucose over SnCl4 after microwave heating at 140 °C for 20 min. This indicated that starch hydrolysis was effectively catalyzed but subsequent glucose isomerization was rate-limited during food waste valorization, which could be enhanced by 40-min reaction to achieve 22.7 wt% HMF from cooked rice. Sugary food waste, e.g., kiwifruit and watermelon, yielded up to 13 wt% HMF over Sn catalyst, which mainly resulted from naturally present fructose. Yet, organic acids in fruits may hinder Fe-catalyzed dehydration by competing for the Lewis sites. In contrast, conversion of raw mixed vegetables as cellulosic food waste was limited by marginal hydrolysis at the studied conditions (120-160 °C and 20-40 min). It is interesting to note that tetravalent metals enabled HMF production at a lower temperature and shorter time, while trivalent metals could achieve a higher HMF selectivity at an elevated temperature. Further studies on kinetics, thermodynamics, and reaction pathways of food waste valorization are recommended.

Abstract
The potential for biochar and hydrochar to adsorb phosphate and ammonium is important for understanding the influence of these materials when added to soils, compost or other high nutrient containing environments. The influence of physicochemical properties such as mineral content, surface functionality, pH and cation exchange capacity has been investigated for a range of biochars and hydrochars produced from waste-derived biomass feedstocks. Hydrochars produced from hydrothermal carbonisation at 250 °C have been compared to low and high temperature pyrolysis chars produced at 400-450 °C and 600-650 °C respectively for oak wood, presscake from anaerobic digestate (AD), treated municipal waste and greenhouse waste. In spite of differences in char physicochemical properties and processing conditions, PO4-P and NH4-N sorption capacities ranged from about 0 to 30 mg g(-1) and 105.8-146.4 mg g(-1) respectively. Chars with high surface areas did not possess better ammonium adsorption capacities than low surface area chars, which suggests that surface area is not the most important factor influencing char ammonium adsorption capacity, while char calcium and magnesium contents may influence phosphate adsorption. Desorption experiments only released a small fraction of adsorbed ammonium or phosphate (<5 mg g(-1) and a maximum of 8.5 mg g(-1) respectively).
