These characteristics make MC suitable for applications in biomedical, food, and packaging industries. Traditionally, Acetobacter aceti has been the primary source for MC production, but recent research has identified other potential microbial producers such as Komagataeibacter xylinus, Sarcina ventriculi, and Rhizobium sp., which offer efficient cellulose synthesis. This study reviews the diverse applications of MC, including wound dressings, edible films, and composites, and discusses cost-effective substrates like sugarcane molasses and fruit waste used in MC production. The paper highlights the importance of sustainable and scalable production methods, exploring the impact of different substrates and environmental conditions on MC yield. Through understanding these factors, the potential for MCbased materials in various industries can be fully realized, promoting environmental sustainability and innovation in material science.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"53 45","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141838098","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 term “organic pollutants” in the present review is considering different types of chemicals including; pesticides, organic matter, dyes and oil spills. The ordinary methods used for remediation of such pollutants from the water environment such as mechanical removal, coagulation, aeration and filtration are defective due to their partial treatment effect in some instances and their high costs in some others. The modification of new, environmentally friend treatment methods are of great concern by abundant environmentalists. Bioremediation is one of new promising techniques that attracting worldwide attention, to completely or partially remove the organic pollutants from the aquatic systems. It is eco-friendly, cost-effective, and suitable for in situ applications. Microbial remediation has been applied to eliminate the toxic and recalcitrant pollutants from the water environment through several mechanisms including biodegradation. This review article provides a survey on the aquatic environment and the main groups of organic pollutants that commonly contaminate it. It also deeply expatiates the multiple applications of microbial bioremediation of such organic pollutants. Moreover, it focuses on some in situ applications of bioremediation technology in some case studies.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"38 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141838259","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}

Actions such as deforestation for logging, intensive agriculture, construction of large hydroelectric dams, pastures for cattle, mining, and construction of roads that favor human access to remote areas have promoted habitat destruction, changes in trophic chains due to nutritional factors, loss of biodiversity, changes in the natural balance of vectors, mammals, hosts and pathogen reservoirs, and closer human contact with wildlife. Another important impact related to changes in land use is forest and habitat fragmentation. According to different investigations, anthropogenic actions causing changes in land use are potential inducers of emergence/reemergence and increased transmission of infectious diseases in the world, including those with pandemic potential. Most of these diseases are classified as zoonoses and many are arboviruses. Deforestation and agricultural intensification seem to be the events that most influence the incidence of zoonoses. Changes in land use may also favor a species jump to a zoonotic pathogen, making it a potential threat to humanity if it acquires an efficient capacity for inter-human transmission. Here, we summarize important evidence on how anthropogenic changes in land use influence the emergence and transmission of infectious diseases to humans.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"57 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139527522","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}

This mRNA is synthesized in a laboratory and packaged into lipid nanoparticles, which protect and facilitate its entry into cells for protein synthesis. Upon injection into the muscle of the recipient, the mRNA instructs cells to produce a protein that is displayed on the surface of the cell, triggering an immune response. The immune system then produces antibodies and activates immune cells to target and eliminate the protein, while also generating memory cells to respond quickly in the event of future pathogen encounters. Available mRNA vaccines, such as Pfizer-BioNTech and Moderna, were developed and authorized for emergency use within a year. These vaccines require extensive cold chain storage, antigen delivery, potential immune response variability optimization, and sophisticated manufacturing process. To improve their effectiveness, stability, and delivery, efforts are underway to explore next-generation mRNA vaccines. Research is focused on enhancing the stability of mRNA vaccines, particularly their temperature sensitivity, to facilitate easier storage and distribution. Self-amplifying mRNA vaccines are also being developed to generate multiple copies of mRNA within cells, potentially leading to a higher production of protein and a stronger immune response. Studies are also exploring new delivery systems using specialized nanoparticles and liposomes to specifically target certain immune cells. Additionally, the development of combination vaccines, including multiple mRNA sequences in single vaccine, is being investigated to protect against multiple strains or variants of particular pathogen simultaneously. Direct delivery of mRNA vaccines into the skin is being explored as a means of enhancing immune response and reducing the required vaccine dose. In summary, messenger RNA vaccines represent a promising new approach to vaccination, with ongoing research aimed at improving their effectiveness, stability, and delivery","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139310895","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 important property of probiotics is direct antimicrobial effects, stimulation of immunity, competing for adhesion site, completion for nutrients and improvement in digestion. Since ancient times different fermented dairy products have been used as the main source of probiotic bacteria. The main objective of this study was to isolate, identify and characterize lactic acid bacterial strains from different fermented dairy products including yoghurt, cheese, buttermilk and curd. To determine the potentials of probiotics different tests like bile tolerance, salt tolerance, acid tolerance and arginine hydrolysis were performed. In the present study it was observed that all the probiotic isolates were able to grow at low pH (2-6) and they were tolerant against NaCl (2%, 4%, 6%) and bile salt concentration (0.2%, 0.4%, 0.6%). The probiotic isolates were shown to be arginine-positive as on a white background they displayed a bright orange colour. The growths of probiotic cultures were observed at different temperature i.e 10 °C and 45°C and were able to ferment different types of carbohydrates such as glucose, sucrose and lactose. The probiotic isolates showed good antimicrobial activities against the four test organisms. The present study showed that the probiotic strains isolated from different fermented dairy products carry antimicrobial property and can be used to control gut microbiota. The observation of the present study showed that dairy products can be used as a good source of potentially probiotic bacteria.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139310706","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}

Pathogens in urine can be detected using a variety of diagnostic approaches, which are broadly divided into laboratory-based and point-of-care (POC) detection methods. Many research institutions and companies working in this subject have strived to establish rapid and accurate pathogen identification because traditional approaches may be timeconsuming. The indications and symptoms are further divided into the following three groups: (1) General signs and symptoms like fever; (2) lower urinary tract symptoms including urgency, frequency, and dysuria; (3) non-specific signs and symptoms such nausea and malaise.

Insect pests populating the farms damage crops leading to food insecurity. The use of chemical insecticides to treat insect infestation is quite popular in Nigeria in area of food crop production and in animal and human health management. These chemical insecticides often pose some health challenges to man and animals hence the need for safer bio-pesticides. Microbial insecticides consist of living cells of microorganisms Research method employed was by collection of secondary data from literatures on previous research works done. These include reports, journal articles, seminars, symposia, and conference papers. Literatures were collected online using the Dennis Osadebay University e-library. These organisms are reared using basic microbiological techniques. Mode of action of microbial pesticides is by contact, which is by entering the host through the outer protective covering or the intestine of the insect. These microbes act on the host (insects) either by elimination or by altering some of their physiological functions. They may act directly on the insects or by the action of their toxins. The toxins can be used independently as bioactive substances in place of the microbial species. Microbial insecticides can be applied as sprays, dusts, liquid drenches, liquid concentrates, wet-table powders or granules. The bio-insecticides have the capacity to ensure the safety of humans and other non-target organisms. They leave less or no residue deposits in food and are ecologically friendly.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139310940","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}
