In recent decades, marine microorganisms have become known for their ability to produce a wide variety of secondary bioactive metabolites. Several compounds been isolated from the development novel bioactives food and pharmaceutical industries. this study, number microalgae were evaluated antimicrobial activity against gram-positive gram-negative bacteria, including plant pathogens, using various extraction techniques assays. Disc diffusion spot-on-lawn assays conducted confirm activity. To...
Abstract Background The study focuses on the global challenge of drought stress, which significantly impedes wheat production, a cornerstone food security. Drought stress disrupts cellular and physiological processes in wheat, leading to substantial yield losses, especially arid semi-arid regions. research investigates use Spirulina platensis aqueous extract (SPAE) as biostimulant enhance resistance two Egyptian cultivars, Sakha 95 (drought-tolerant) Shandawel 1 (drought-sensitive). Each...
Nannochloropsis sp. has been a very attractive microalgae species because of its high omega-3 fatty acid content. However, it is also one the with strongest cell wall. Currently, energy-intensive mechanical techniques and harmful flammable organic solvents are used for extracting lipids from biomass. Thus, in this study, cholinium [Ch] amino acid-based ionic liquids (ILs) were investigated their capability to extract Among all ILs tested, arginate ([Ch][Arg]) extracted highest amount leaving...
Abstract Background Beet filter cake (BFC) is a by-product of sugar beet processing, which difficult to dispose and involves severe environmental concerns. Spirulina platensis microalga with high protein content essential for human animal nutrition. The present study aimed utilize the extract (BFCE) produce commercially . However, cultivation S. on BFCE economically single-cell has not been reported previously. Results batch experiment revealed maximum dry weight at Zarrouk’s medium (0.4...
For efficient downstream processing, harvesting remains as one of the challenges in producing Nannochloropsis biomass, a microalga with high-value omega-3 oils. Flocculation is an effective, low-energy, low-cost method to harvest microalgae. Chitosan has been shown be effective food-grade flocculant; however, commercial chitosan sourced from crustaceans, which disadvantages including concerns over heavy-metal contamination. Thus, this study tests flocculation potential mushroom chitosan. Our...
Abstract Food‐grade rather than synthetic or chemical flocculants are needed for microalgae harvesting by settling, if used food products. Chitosan is effective in freshwater microalgae, but it expensive and typically not suitable marine like Nannochloropsis . To minimize costs food‐grade flocculation, a number of potentially important parameters considered, including chitosan solubility optimized chitosan‐mediated flocculation sp. BR2 five‐factor central composite design experiment. Results...
Abstract Background Beet filter cake (BFC) is a food-grade solid waste produced by the sugar industry, constituting permanent source of pollution. Cyanobacteria are considered sustainable resource for various bioactive compounds such as phycocyanin pigment with valuable applications. This study aimed to use beet extract (BFCE) an alternative medium economic cultivation cyanobacterium Leptolyngbya sp. SSI24 PP723083, then biorefined component that could be used in production selenium...
T HE growth of Dunaliella salina SA20 (Dunal) Teodoresco Egyptian isolate (from El- Bardawil Lake, Sinai, Egypt) in wastewater is a more cost-effective cultivation method.Wastewater, such as mozzarella cheese whey (MCW), produced massive quantities dairy industry byproduct, and growing D. waste could be used safely biotechnological applications.Applying different organic MCW ratios to inorganic Loeblich nutrient medium (20, 50, 75% v/v MCW/Loeblich) supplement allowed mixotrophic nutrition,...
Background:The most hazardous wastewater sources in the northern part of Middle Nile Delta, Egypt; receiving a massive amount agricultural, industrial, and sewage drainage are Kitchener drain which is one tallest systems, Burullus Lake represents 2nd largest Egyptian coastal lake.Results: The current work to determine abundance frequency cyanophytes, chlorophytes, bacillariophytes correlation between them environmental abiotic components.Among sixty nine microalgal species, 19 species belong...
