These agro-wastes are termed lignocellulosic biomass as they contain cellulose, lignin and hemicellulose in abundance. Nanocellulose has its dimensions in nanoscale with excellent and distinctive attributes that attract researchers. Nanocellulose matrices are broadly categorised as nanocellulose crystals, nanocellulose fibrils and bacterial nanocellulose. Nanocellulose possesses some extremely significant properties, including biodegradability and biocompatibility, high aspect ratio, better mechanical attributes, easy surface modification, crystallinity, non-toxic nature, and water absorption capacity, making it a perfect material for a wide range of applications. The presence of hydroxyl groups on the surface of nanocellulose helps in its easier surface modification by various processes like carboxylation, silylation, esterification, amidation and etherification, which further allows its application as functional material. This review encompasses a brief discussion of the pre-treatments of lignocellulosic biomass, the different isolation processes of nanocellulose and the surface modification done to improve dispersibility in the polymer matrix. In this review, the different applications of nanocellulose in food industries, in biomedical and pharmaceutical fields, and their safety issues and toxicity to humans and the environment have also been briefly discussed.</p>","PeriodicalId":754,"journal":{"name":"Reviews in Environmental Science and Bio/Technology","volume":"22 1","pages":"1 - 27"},"PeriodicalIF":14.4,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4749638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A massive quantity of agricultural/food processing waste has been employed alone or in combination to make biodegradable packaging material with good barriers and functional capabilities.

To meet consumer demand, the onion processing industry focuses on onion-based value-added products such as peeled onion, onion paste, onion powder, etc., that generate a considerable amount of solid waste (OSW). This OSW cannot be fit for animal fodder, landfill, and incineration due to their high carbon content and phytopathogens. OSW was found to be explored in the packaging sector because of high cellulose, lignin, and polyphenols. The biopolymers and pigments in OSW can be effectively used in active/smart packaging, which will aid in monitoring packaged food quality. The pigments and bioactive components in OSW can serve as indicators, maintaining the freshness of packaged foods in real-time by visual examination and reducing food loss and waste.

In this context, biological ore beneficiation is spurring increasing interest from scientists and industrials. The latest scientific developments in bio-metallurgy have allowed it to exploit biotechnologies in the flotation process as a novel/cleaner approach for separating gangue materials from valuables minerals. Current fundamental research projects have focused on the progress of biotechnology and the employment of biopolymers, microorganisms, and their metabolites, as well as plant-derived biosurfactants in the emerging field of bioprocessing, particularly bioflotation. Almost all studies on flotation have focused on chemical and physical parameters, and the role of natural biosurfactants remains little explored. This review presents a thorough understanding of the bioflotation concept by assessing previous research on several elements of bioflotation, including the impacts of biotechnology and operating factors (pH, biomass, and biosurfactants concentration), probable mechanisms, and unexplored areas, but from various pragmatic viewpoints. Recent studies are summarized by categorizing microorganisms, plants, and biopolymers based on their bioflotation performances. Furthermore, the most recent research investigations on biological flotation of specific minerals (salt-type sulphide and oxide) are reviewed. Finally, critical challenges of bioflotation are discussed, and novel perspectives are provided to contribute to solving the difficulties faced in its implementation.</p><h3>Graphical abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":754,"journal":{"name":"Reviews in Environmental Science and Bio/Technology","volume":"22 1","pages":"105 - 131"},"PeriodicalIF":14.4,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5161577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many of these chemicals are poorly characterized because of lacking data on their use, environmental fate and toxicity, as well as lacking detection techniques. These compounds are sometimes referred to as contaminants of emerging concern (CECs). Urban areas are an important source of CECs, where these are typically first collected in sewer systems and then discharged into the environment after being treated in a wastewater treatment plant. A combination of emission estimation techniques and environmental fate models can support the early identification and management of CEC-related environmental problems. However, scientific insight in the processes driving the fate of CECs in sewer systems is limited and scattered. Biotransformation, sorption and ion-trapping can decrease CEC loads, whereas enzymatic deconjugation of conjugated metabolites can increase CEC loads as metabolites are back-transformed into their parent respective compounds. These fate processes need to be considered when estimating CEC emissions. This literature review collates the fragmented knowledge and data on in-sewer fate of CECs to develop practical guidelines for water managers on how to deal with in-sewer fate of CECs and highlights future research needs. It was assessed to what extent empirical data is in-line with text-book knowledge and integrated sewer modelling approaches. Experimental half-lives (<i>n</i> = 277) of 96 organic CECs were collected from literature.

An over-reliance on their application to crops to control pests can disturb ecosystems. Therefore, the scientific community and policymakers must be aware of the commitment and active stance they need to take up to effectively elaborate on solutions toward mitigating environmental contamination over the coming few years. We, therefore, reviewed the academic literature on bioremediation from 2018 to 2021 (the latest year of complete publication) to provide a meta-analysis of microbial systems capable of dissipating pesticides from agricultural soils. Natural attenuation can control lindane; however, it is time-consuming and unconvincing to scale. By introducing a suite of microorganisms into the system for substrate-specific biodegradation, we can boost the bioprocess and ultimately level up its cost-effectiveness. Options of microorganisms for bioaugmentation include the fungus <i>Trametes versicolor</i> and the bacteria <i>Pigmentiphaga</i> spp. and <i>Paenanthrobacter</i> spp. Bioaugmentation and biostimulation are enablers of environmental reclamation in agroecosystems. However, those biocatalytic strategies can be costly while manifesting as degraders to ecological sustainability. For instance, allochthonous and recombinant microorganisms can reduce genetic diversity by promoting antagonistic relationships. In addition, some stimulant minerals can be more toxic and harmful to beneficial non-target organisms than the target pesticide. Prudence and safety are significant aspects of ensuring environmentally safer applications for pesticide-degrading approaches. Therefore, our analytical insights can provide knowledge to progress the field’s prominence in developing high-throughput microbiological removal of hazardous active compounds from agricultural soils.</p></div>","PeriodicalId":754,"journal":{"name":"Reviews in Environmental Science and Bio/Technology","volume":"21 4","pages":"851 - 876"},"PeriodicalIF":14.4,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11157-022-09637-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4591409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, recently, a class of phototrophic bacteria, purple non-sulphur bacteria (PNSB), has emerged as a favourable option in terms of both wastewater treatment and resource recovery. PNSB are metabolically versatile and tolerant to a wide range of conditions, hence their ability to thrive in diverse waste streams.

Recent evidence also indicates that PNSB-based aquafeed enhances growth and boosts immunity in certain aquaculture trials. It does not possess the same toxicity as most gram-negative bacteria due to its comparatively less potent lipopolysaccharide composition. With diverse promising prospects of PNSB-based SCP, it is critical to extensively examine the landscape from a holistic standpoint, highlighting the potential challenges large-scale SCP production may pose.

The genus <i>Nitrospira</i> is the most diverse among nitrifying microorganisms and of significant importance in nitrification in natural and engineered environments. These microorganisms are versatile, and niche differentiation has been observed even at the same lineage level. In general, bacteria of the genus <i>Nitrospira</i> can adapt to a wide range of conditions such as substrate concentrations, dissolved oxygen, and temperature. However, environmental and operating factors governing the presence and abundance of these organisms in different habitats are still not completely understood. Nitrite-oxidizing bacteria and complete ammonia oxidizers (comammox) of the genus <i>Nitrospira</i> are the nitrifying organisms frequently predominant in wastewater treatment plants. <i>Nitrospira</i> may also be associated with opportunities for wastewater treatment such as bioprocesses that consume less energy for aeration and produce a smaller volume of pollutant gases during nitrification. Nevertheless, the genus <i>Nitrospira</i> has not yet been completely characterized, and very few isolates have been obtained, making it difficult to investigate their unique metabolism for wastewater treatment. Therefore, to fill knowledge gaps and improve the understanding of the ecophysiology and importance of <i>Nitrospira</i>, it is crucial to develop an integrated strategy for the cultivation, identification, and characterization of these microorganisms.
