Curcuma longa L. (turmeric), Beta vulgaris (beetroot), and Daucus carota (carrot) grown in Bangladesh were analyzed for nutritional phytochemical contents to reveal their comparative compositions antiradical properties. Ash, protein, carbohydrate content significantly preeminent beetroot as compared others. Whereas fat was found be high turmeric, carrots contained a great percentage of crude fiber. Beetroot shown have much greater potassium, calcium, iron levels than Regarding amino acids,...

<title>Abstract</title> Microalgae are a diverse group of eukaryotic organisms that thrive in various habitats and have significant potential as alternatives to fossil fuels sources valuable chemicals like PUFAs, carotenoids, antioxidants. Despite their efficiency biomass production, utilizing microalgae effectively poses challenges. grow aqueous media must be dried before being used for biofuel chemical extraction, or nutraceutical products. While extensive research exists on microalgae's...

In this study, an effective environment for Chlorella vulgaris growth is sought after. As a substitute source of food and feed, increasing the cell density culture one keys to ensuring sustainability. It can be showed from different studies that optimum light intensity pH could increase density. effects on rate C. were observed in photobioreactor. A specific wavelength (682 nm) was determined by UV-Vis Spectrophotometry carry out further analysis. The intensities set at 7409, 9261 11,113...

Cladoceran Moina macrocopa is an important zooplankton for juvenile fish and crustacean, widely used as live feed in aquaculture. In this experiment, five different culture media denoted mixed (Treatment-1), Chlorella (Treatment-2), Spirulina (Treatment-3), dried cattle (cow) manure (Treatment-4), baker’s yeast (Treatment-5) was prepared to M. macrocopa. According the proximate composition data, enriched found significantly with higher protein content lower lipid among all treatment groups....

Microspheres, a potential drug delivery approach, has opened new era for attaining versatile release patterns needed. By optimizing the formulation variables, they can be prepared to obtain targeted release, immediate sustained patterns. The of active material depends upon number parameters such as polymers, stirring speed (rpm), methodology, surfactants, etc. Fexofenadine hydrochloride (HCl) is second generation antihistamine. Our present research explored effects using different rpm (600-...
