This study aimed to determine the influence of nitrogen stress in the form of potassium nitrate (KNO3 ) by altering the standard recommended nitrogen concentration to characterize the growth performance, proximate composition, and pigments content. The nitrogen concentration was arranged in following order for the culture of Nannochloropsis sp.: 50 g/L, 75 g/L, 100 g/L (standard), 125 g/L, and 150 g/L of KNO3 . All growth parameters, proximate composition, and pigment contents showed significant (p < 0.05) changes among the treatments. Cell density was increased by 2.48 folds, SGR was increased by 56.9%, and cells were doubled in number at a pace of 12.192 hours faster at the maximum nitrogen concentration (150g/L KNO3 ). The maximum protein content was 54 ± 1.05% at 150 g/L KNO3 while the highest lipid content was 36 ± 0.32% at 75 g/L KNO3 . The highest carbohydrate content was 24 ± 2.51% at 100 g/L KNO3 . The chlorophyll a content was increased to 0.632 ± 0.049 µg/L at 150 g/L KNO3 , while the highest carotenoids content was 3.301 ± 0.052 µg/ml at the 75g/L KNO3 . On the other hand, phycobiliprotein content was the highest 0.028 mg/g for the standard concentration of KNO3 . This study provides the commercial cultivation strategy for Nannochloropsis sp. by revealing the biomass productivity, biochemical and bioactive compounds status at different nitrogen-based culture conditions that will ensure their multipurpose use in aquaculture, pharmaceuticals, and nutraceuticals sectors.","PeriodicalId":280200,"journal":{"name":"Journal of Aquaculture & Livestock Production","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115542287","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}
