The special microbial consortia (J-6 and J-1) obtained from decayed wooden relics were selected. The bacteria of original microbial consortium J-6 mainly included Shinella , Cupriavidus and Bosea . The bacteria of original microbial consortium J-1 mainly included Serratia and Yersinia . The fungi of J-6 and J-1 were dominated by Saccharomycetales. The performances of two microbial consortia in wastewater treatment were compared, and the changes in community structure were analyzed to study the relationship between microbial consortium structure and degradation efficiency. For the treatment of model Chinese medicine wastewater, the optimal degradation conditions were treatment temperature of 30 °C, initial pH of 7, dissolved oxygen of 2 mg L –1 , and treatment time of 96 h. The COD (Chemical Oxygen Demand) removal efficiency reached 95.25 % by J-1. For the treatment of model papermaking wastewater, the optimal degradation conditions were treatment temperature of 30 °C, pH of 5, dissolved oxygen of 3 mg L –1 , nitrogen source concentration of 0.1 g L –1 , and treatment time of 120 h. The COD removal efficiency reached 86.8 % by J-6. Bacteria played a significant role in the degradation of lignin-containing wastewater, and the bacterial consortium abundance may promote the degradation of organic substances in the wastewater. The dominant strains were different in Chinese medicine wastewater and paper-making wastewater systems. The correlation between microorganisms and the difference in the abundance of bacteria groups may be the reason for the different performances of the two microbial consortia in treating different lignin-containing wastewaters.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":"1 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67064166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To tackle this challenge, we conducted an inves-tigation on a nanoparticle-based aqueous two-phase system (ATPS), incorporating polyethylene glycol (PEG) and dextran (DEX). The primary objective was to develop an ATPS that is non-alkaline, operates under mild environmental conditions, and is both non-toxic and cost-effective. The study focused on identifying a suitable nanoparticle that could improve the partitioning of vanillin in ATPS and facilitate economically favorable separation processes. Various nanoparticles were evaluated as additives to enhance vanillin partitioning. The study explores the influence of parameters, such as polymer weight percentages and DEX molecular weight on vanillin partitioning and recovery percentage. Additionally, the impact of incorporating different nanoparticles was assessed in the optimized system composed of 6.5 wt% PEG6000 and 7.8 wt% DEX15000. Results indicate that the addition of only 0.001 g of silver nanoparticles to the optimal system improved the partition coefficient by 42 % and the vanillin recovery percentage by ap-proximately 8 %","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49396060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surfactants are emerging contaminants that pose a significant problem in wastewater treatment, and their presence causes difficulty in traditional treatment processes. In this context, the present work critically reviews the impacts of surfactants and their toxicity on the environment and human health while presenting the various techniques used in wastewater treatment plants to reduce their effects. Surfactants are removed from wastewater using different techniques, including physical, chemical, biological, and membrane treatment. The choice of the most appropriate technique for wastewater treatment is based on many criteria, such as effluent quality, standards to be respected, investment and operating costs, and environmental footprint. Adsorption and coagulation-flocculation are the most suitable techniques for removing detergents from wastewater due to their effectiveness, ease of use, environmental friendliness, and cost-effectiveness.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49093269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Akaike criterion revealed that in 55.2 % of the examined samples, the best approach (among those considered) to determine G relied on the mechanical spectrum fitting by the generalised Maxwell model with relaxation times scaled by a factor 10. Thus, this approach was adopted to evaluate the mesh size distribution combining G knowledge with the determination of the average magnetic relaxation time ( T 2m ) of sputum. As G and T 2m determination can be negatively affected by sputum contamination by saliva, whose presence increases T 2m and depresses G , we developed a proper “decontamination” procedure to obtain more reliable T 2m and G estimations (necessary in 21 % of the samples).

Functional polymeric materials from renewable feedstocks that do not conflict with food and animal feed, and their renewal through biodegradation under diverse environmental conditions as the desired end-of-life option indeed constitute a paradigm shift for today’s plastics industry. Considering the ever-in-creasing environmental problems associated with the disposal or incineration of fossil plastics, the increasing microplastic formation, food contamination, and rising atmospheric CO 2 concentrations, have made it clear that the time is ripe for alternative, inno-vative, and sustainable polymers with plastic-like properties. In this nexus, the present review shines new light on the benefits of biobased and, at the same time, biodegradable microbial polyhydroxyalkanoate (PHA) biopolyesters. Special emphasis is dedicated to carbon recyclability through biodegradability and compostability of these fascinating natural materials, which are slowly but surely being commercialized as replacement for fossil plastics that are produced and disposed of in multi-million-ton scale annually, resulting in a growing environmental threat. This review highlights that end-of-life options of PHA are analogous or even superior to another well-known polymer from nature, cellulose, while PHA offer the additional attributes of plastics in use with tailor-made properties. Finally, the review demonstrates how PHA biopolyesters can contribute to reaching many of the heavily discussed and desired UN Sustainable Development Goals.","PeriodicalId":9765,"journal":{"name":"Chemical and Biochemical Engineering Quarterly","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42472554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
