Microalgae have the potential as a source of biofuels due to their high biomass productivity and ability grow in wide range conditions, including wastewater. This study investigated cultivating two microalgae species, Oocystis pusilla Chlorococcus infusionum, wastewater for biodiesel production. Compared Kühl medium, KC medium resulted significant fold increase cellular dry weight production both O. C. with an 1.66 1.39, respectively. A concentration 100% highest growth pusilla, lipid...
Phaeodactylum tricornutum is a versatile marine microalga renowned for its high-value metabolite production, including omega-3 fatty acids and fucoxanthin, with emerging potential integrated biorefinery approaches that encompass biofuel bioproduct generation. Therefore, in this study we aimed to optimize the cultivation conditions boosting biomass, lipid, fucoxanthin production P. tricornutum, focusing on impacts of different nutrient ratios (nitrogen, phosphorus, silicate), glycerol...
Bioactive molecules derived from seaweed extracts are revolutionary bio-stimulants used to enhance plant growth and increase yield production. This study evaluated the effectiveness of a commercially available liquid extract, namely, True-Algae-Max (TAM®), as stimulant on nutritional, antioxidant activity Capsicum annuum. Three concentrations TAM® (0.25, 0.5, 1%) various NPK: ratios were investigated via foliar spray, over 2017 2018 cultivation seasons, under greenhouse conditions. is rich...
This study aimed to understand the effect of commercial seaweed extract as a biofertilizer, named True-Algae-Max (TAM®), on yield, nutritional, antioxidant, and cytotoxic activity Eruca vesicaria. Three concentrations TAM® (5, 10, 15%) were studied by foliar spray over two cultivation years (2016 2017) without any chemical fertilizer, along with control consisting synthetic nitrogen, phosphorus potassium (NPK) fertilizers. The yield composition E. vesicaria significantly improved in all...
Abstract Ulvan is a sulfated heteropolysaccharide present in the cell wall of Ulva species with unique structure and biological potential used various fields. Chemical characterization was carried out to determine ulvan from fasciata Delile collected Eastern Harbor, Alexandria coast, Egypt. contains 31.5% carbohydrate total content 43.66% (13.75 g/100 g DW) sulfate 20.45% ulvan. FTIR spectrum presented signals ester (C–O–S) groups (S=O), typical for GC–MS revealed that mainly composed...
Microalgae, with their high adaptability to various stress conditions and rapid growth, are considered excellent biomass resources for lipid production biodiesel feedstocks. However, yield productivity of the natural strains common bottlenecks in large-scale use production, which can be overcome by evolving new using conventional advanced mutagenic techniques. It is challenging generate microalgae capable synthesis through selection. As a result, random mutagenesis currently viable option...
Energy is the basis and assurance for a world's stable development; however, as traditional non-renewable energy sources deplete, development study of renewable clean have emerged. Using microalgae carbon source anaerobic bacteria to generate biohydrogen generation system that both local global peers see promising.Klebsiella pneumonia, Enterobacter cloacae, their coculture were used synthesize using Oscillatoria acuminata biomass via dark fermentation. The total carbohydrate content in O....
Biological water quality is one of the main indicators pollution. The objective current study was to assess El-Temsah Lake, Egypt, in 2018 using phytoplankton and physicochemical indices (e.g. species richness, diversity, equitability, Palmer indices). Spatio-seasonal variability phytoplanktons, qualitative status physiochemical parameters assessed 20 sample sites Lake during winter summer seasons 2018. Our results indicated that abundance comprised 105 from 69 genera 101 68 winter. Navicula...
This study investigated the effects of different concentrations CaCl2 (10 and 15 mol m−3) on growth, physiology, cytological characteristics salt-stressed Vicia faba (L.) seedlings grown under greenhouse conditions. Salinity stress (150 m−3 NaCl) had detrimental all measured growth parameters, increased micronucleus count number (MCN) by 26.6 micronuclei/1000 cells, decreased mitotic index (MI) 66.6%, caused various chromosomal aberrations, nuclear alterations, chromatin bridges in compared...
