{"title":"A Comprehensive Review on Zebrafish and Zebrafish Embryonic Stem Cells (Zescs) as the Versatile Biotechnological Green Tool for Detecting Environmental Pollutants","authors":"Divya Christy.L, Jayshree Nellore","doi":"10.13005/bbra/3131","DOIUrl":"https://doi.org/10.13005/bbra/3131","url":null,"abstract":"This article discusses the embryonic development of zebrafish, which are essential aquatic models for investigating neurotoxicity caused by environmental toxins. Zebrafish are one of the few fish species that can survive in highly toxic environments, making them an interesting model for assessing pollutants' performance and determining their toxicity. Zebrafish's limited life expectancy, ease of maintenance and growth, transparent embryos, and homology of genetic and biological features make them an interesting tool for studying the effects of common substances like insecticides, nanoparticles, and food supplements on human health. The study focuses on the regulation of morphology and behavior, stress caused by oxidative damage, transcription, neurogenesis, and neuron progression. Further research is needed at cellular and signaling levels to understand the detrimental processes of pollutants in relation to epigenetic toxicity, negative interference of the BB barrier, and manipulation of the brain-gut-microbiota axis. Environmental pollution is a significant issue that poses a severe threat to public health. Biotechnological principles are now being widely used to monitor environmental pollutants due to their versatile applications. In this regard, zebrafish has established as a prominent vertebrate prototype organism, which offers a unique platform for toxicity screening and efficacy testing of various chemicals. Studies have shown that exposure to toxicants during embryonic development can cause developmental, cardiovascular, and neurodevelopmental toxicity, as well as hepatic disorders in zebrafish. Therefore, zebrafish has been extensively used to study the neurotoxicity of environmental pollutants, including pesticides, nanoparticles, food additives, and other pollutants. Additionally, the review discusses the use of zebrafish-derived embryonic stem cells (ZESCs) for environmental pollutants monitoring. Stem cells are highly sensitive to the toxicity of environmental chemicals during embryogenesis, which can lead to adverse effects on embryonic and fetal development. Thus, ZESCs cultivation and utilization in toxicological assays have become a valuable tool for evaluating the toxicity of potential environmental toxicants. The application of green science principles to evaluate the toxicity of environmental pollutants using zebrafish and ZESCs has enormous potential. This approach offers a sustainable and environmentally friendly way to monitor pollutants, and it can contribute to the development of effective mitigation strategies. Overall, the use of zebrafish and ZESCs in biotechnological pollutants monitoring could have far-reaching effects for public health and environmental sustainability.","PeriodicalId":9032,"journal":{"name":"Biosciences, Biotechnology Research Asia","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135546107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taub in terms of callus growth (monitored for 60 days) evaluated for total phenolic and flavonoid content, SPF and the effect of jasmonic acid on these parameters. A good correlation of 0.73 between SPF and TFC was obtained with the application of jasmonic acid. Assessment of phytochemical composition of callus from both varieties revealed the presence of different isoflavones, flavones, flavanones, chalcones classes of flavonoids that could possibly be responsible for good SPF. The growth index was the highest for the red variety in media without the elicitor, contrary to the results of the yellow variety, where 1 µM JA was found to increase the growth index. Differences were also noticed in the total phenolic content (173.84 mg GAE/g and 165.65 mg GAE/g) total flavonoid content (10.50 mg QE/g and 6.31 mg QE/g) and Sun Protection Factor (19 and 14.5) between the red and yellow variant callus respectively.","PeriodicalId":9032,"journal":{"name":"Biosciences, Biotechnology Research Asia","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135546997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contemporary uses for nanocomposites are expanding constantly, and they are being used in many different industries. Nanocomposites are used in a variety of products, such as solid polymer electrolytes for batteries, impellers and blades, oxygen and gas barriers, food packaging, thin-film capacitors for computer chips, and fuel tanks and engine parts. As drug - delivery techniques, anti-corrosion shield coatings, UV protection gels, oils, scratch-free paint, new scrape resist materials, new fire-retardant materials, superior fibres and films, etc., they also find extensive application. Extensive use of these composites led to the discloses of these stuffs into the environment and properties of these materials are greatly influenced by the presence of pollution. The physico-chemical properties of these nanocomposites are very important for predicting their fortune and behavior in the environment and their toxicity to living organisms. Limited data on the ecotoxicity of these materials are available and even those are confined to a few organisms like bacteria, algae, invertebrates, fishes and mammals. Detailed studies on the adsorption, distribution, metabolism and excretion on higher organisms is the need of the hour. Presently the environmental risk assessment of nanomaterials is being performed using the existing methodologies and modification of the methodologies are required.

The enhanced risk of infection, especially those brought on by bacteria that are multi-drug resistant, is one of the main side effects of chronic kidney disease. It is essential to screen and identify multidrug resistant bacteria in chronic kidney disease patients, especially those receiving haemodialysis, in order to prevent the transmission of these pathogens. Hence, to improve outcomes for chronic kidney disease patients, early diagnosis and prompt treatment of drug-resistant bacteria are essential. A total of 2219 samples were screened for antibiotic resistant microbes in hospital samples. 445 samples tested positive (20.05 %) for bacterial growth and 1774 samples tested negative (79.94 %). The rate of multidrug resistance bacterial infections was 17% and 43% higher in CKD patients for estimated glomerular filtration rate between 30 and 59 ml/min/1.73m2 and glomerular filtration rate 30 ml/min/1.73m2 respectively. Five bacterial isolates were found to exhibit multi-antibiotic resistance. The Multiple Antibiotic Resistance (MAR) Index ranged from 0.3 to 0.7 across the isolates. The isolates were identified as Enterobacter bugandensis, Enterococcus faecium, Providencia stuartii, Klebsiella variicola, and Escherichia coli by 16S rRNA gene sequencing and phylogenetic analysis. In conclusion, screening and identification of multidrug resistance bacteria is essential to prevent and control the spread of these pathogens and will be helpful for the effective treatment of the multidrug resistance in chronic kidney disease patients.","PeriodicalId":9032,"journal":{"name":"Biosciences, Biotechnology Research Asia","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135547138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, pure bee pollen synthesized by the giant honeybee Apis dorsata dorsata was investigated for the presence of phytochemicals. The extraction of bioactives was done using 30% ethanol and 70% methanol. To develop wound dressing fabric with biomedical applications, phenolics derived from bee pollen were covalently bound to amino polyethylene terephthalate (PET) fabric by immobilization using polyethylene glycol diglycidyl ether (PEGDGE) as a cross-linker. Alterations in the chemical configuration were studied using ATR-FTIR spectra and the contact angle of 122° in unmodified PET decreased to 110° and 98° post amination and immobilization. Antibacterial activity of the immobilized fabric was observed against bacteria and yeast isolated from burn wounds. Thus, the study revealed that PET fibrous mats in the presence of bee pollen could be considered potential wound dressing materials due to their enhanced processing capabilities and suitable structural properties. As not much research has been conducted on bee pollen previously, this study sets out to examine its efficacy and therapeutic utility in connection to burn wound healing capabilities.","PeriodicalId":9032,"journal":{"name":"Biosciences, Biotechnology Research Asia","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135546102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The utilization of microorganisms to convert cellulose into valuable products has gained significant attention worldwide. This study aims to isolate novel cellulase-producing microorganisms and investigate the influence of dietary and physicochemical factors on cellulase production, as well as evaluate the potential applications of a selected isolated strain. Materials and Methods: The Bacillus amyloliquefaciens strain was identified as the most efficient producer of cellulase among various cellulase-producing bacterial strains isolated during the research. The morphological and biochemical characteristics of this strain were characterized. To determine the optimal conditions for cellulase production, various parameters such as raw substrates, carbon sources, nitrogen sources, temperature, inoculum age, inoculum size, agitation rate, incubation duration, and pH were investigated. Results: The study found that sugarcane bagasse, molasses, and paper pulp exhibited the highest cellulase production capacity, with respective enzyme activities of 0.97, 0.98, and 0.88 IU/mL. Maximum cellulase production occurred at a temperature of 37°C, an inoculum size of 2.5%, an inoculum age of 24 hours, an agitation rate of 120 rpm, an incubation time of 48 hours, and a pH of 7 with 1% peptone. The Bacillus amyloliquefaciens isolate was successfully applied to convert lignocellulosic waste into ethanol and fermentable sugars through saccharification and fermentation of cellulose, demonstrating its significant effectiveness. Conclusion: Bacillus amyloliquefaciens strain isolated in this study proved to be a highly efficient producer of cellulase. The optimized production media led to improved enzyme production, and the isolate showed promising results in the industrial application of converting cellulosic waste into ethanol. The 16s rRNA sequencing confirmed the identity of Bacillus amyloliquefaciens , which was deposited under the accession number MN081796 in the NCBI database. In this study we discussed the possible low-cost, enzymatic pretreatment methods of lignocellulosic material in order to use it as an efficient raw material for biofuel production.
