The effectiveness of this method was studied to obtain an alternative approach that is easy to be handled with low cost and energy in removing the lead from residual water. Optimum parameters were analyzed to determine the effectiveness of lead removal, including pH, alum dose, and A. jiringa seed peel extract dose. A study on the coagulation-ﬂocculation process with and without the aid of A. jiringa was also conducted. The optimum pH, the alum dose, and the A. jiringa seed peel extract dose were 9.0, 2.44 g / l, and 60.2 mg / l, respectively. The percentage of lead removal with the aid of A. jiringa seed peel extract was 79%, and the percentage was dropped to only 47% without the extract. A signiﬁcantly higher rate in the coagulation-ﬂocculation process due to the presence of A. jiringa seed peel extract proved its effectiveness in removing lead from wastewater.","PeriodicalId":21577,"journal":{"name":"Scienceasia","volume":"1 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68621411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Any alteration in the microbial population or breach in the symbiotic alliance with the host may ultimately lead to development of different kinds of pathologies. Realization of the enormous role played by the microbiome in health and diseases of human and domestic livestock led researchers to find ways to modulate these resident microbiomes for improvement in health and management of diseases. Theoretically there are several ways that can be employed for manipulating the composition and functional capacity of the resident microbiome, which may lead to improvements in human and livestock health. Though studies have shown therapeutic potential of the microbiome, considerable challenges exist in the actual implementation of these strategies in clinical settings. This review discusses the symbiotic relationship between microbiome and host and strategies to modulate host immune responses by manipulating microbiome profile. Paper also highlights how to overcome existing obstacles for successful implementation of microbiome manipulation techniques. In this era of COVID-19, it would be worth analysing the role of resident microbiome in the magnitude of COVID-19 severity which may have occurred through immunomodulation.","PeriodicalId":21577,"journal":{"name":"Scienceasia","volume":"1 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68622086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
