B2E Technological Sonar Initiative #30
The latest issue of B2E Technological Sonar Initiative highlights exciting advances in aquaculture and marine biotechnology. Discoveries such as the use of Fremyella diplosiphon as a food supplement and the FALCON Biomass monitoring technology are boosting the efficiency and sustainability of aquaculture production. In addition, new solutions for detecting fish spoilage and seaweed-based therapies promise to revolutionise the industry. Explore these innovations that are shaping the future of living marine resources.
AQUACULTURE
Fremyella diplosiphon as a Nutritional Feed Supplement for Aquaculture
A method for improving aquaculture growth and/or survival rate and hemocyte viability, comprising growing the aquaculture in the presence of cyanobacteria F. diplosiphon. The aquaculture may be a shellfish aquaculture, for example, shrimp, crayfish, oysters, clams, mussels, and crabs or combinations thereof.

Monitoring technology to revolutionise land-based farming
A partnership agreement signed between MSD Animal Health and First Water (project of land-based Atlantic salmon farming) of Iceland promises the deployment of FALCON Biomass – an innovative fish monitoring technology –- for land-based farming in Iceland. Developed with over 25 years experience in the measurement of fish in sea net-pens, the FALCON Biomass system combines advanced vision technology with years of research, resulting in a farming solution that delivers key insights into fish growth.

Sea Cucumber Polysaccharide from Stichopus japonicu and Its Photocatalytic Degradation Product Alleviate Acute Alcoholic Liver Injury in Mice
In the present study, the hepatoprotective effects of a sea cucumber sulfated polysaccharide (SCSP) isolated from Stichopus japonicu were investigated. A low-molecular-weight derivative of SCSP (dSCSP) was prepared by using the photocatalytic method and further analyzed with infrared spectroscopy (IR), nuclear magnetic resonance (NMR), high-performance liquid chromatography-mass spectrometry (HPLC-MSn), and other techniques. The in vivo experiment showed that the addition of SCSP or dSCSP to Baijiu (grain- brewed wine) could alleviate alcoholic liver injury in mice. Further analysis also revealed their protective effect in reducing oxidative stress damage and in regulating the glycerophospholipid metabolism in the liver.

Mitigating drought stress in wheat plants (Triticum Aestivum L.) through grain priming in aqueous extract of Spirulina platensis
The research investigates the use of Spirulina platensis aqueous extract (SPAE) as a biostimulant to enhance the drought resistance of two Egyptian wheat cultivars, Sakha 95 (drought-tolerant) and Shandawel 1 (drought-sensitive). Several parameters of the flag leaf were assessed: agronomy, pigment fractions, gas exchange, and carbohydrate content Moreover, at the harvest stage, yield attributes and biochemical aspects of yielded grains (total carbohydrates and proteins) were also evaluated. The study demonstrated that SPAE treatments significantly enhanced the growth vigor, photosynthetic rate, and yield components of both wheat cultivars under standard and drought conditions.

Colorimetric Indicator Based on Gold Nanoparticles and Sodium Alginate for Monitoring Fish Spoilage
In this work, a colorimetric indicator based on gold nanoparticles (AuNP) and a biodegradable and eco-friendly polymer (sodium alginate, Alg.), was developed for the real-time detection of fish spoilage products. The results indicated color changes of the indicator in packaged fish on day 9 of storage at a refrigerated temperature (5°C). These results showed the successful application of the colorimetric indicator in the detection of the total volatile basic nitrogen (TVB-N) in packaged fish.

Wound healing potential of Cystoseira/mesenchymal stem cells in immunosuppressed rats supported by overwhelming immuno-inflammatory crosstalk
This study aimed to assess the wound-healing efficacy of Cystoseira brown algae extract alone and in combination with stem cell therapy. Additionally, it was investigated the metabolomic profiling secondary metabolites of the brown alga Cystoseira and evaluated its potential for wound healing in immunocompromised mice in conjunction with the mesenchymal stem cells in the combined capacity of the bone marrow (BMMSC) injection, monitored by histopathological as well as PCR analytical techniques. The findings indicate that the primary compounds of Cystoseira holds potential wound healing therapeutic activity.

Bionanofactory for green synthesis of collagen nanoparticles, characterization, optimization, in-vitro and in-vivo anticancer activities
Collagen nanoparticles (collagen-NPs) were bio-fabricated from pure marine collagen using the cell-free supernatant of a newly isolated strain, Streptomyces sp. strain NEAA-3. The biosynthesized collagen-NPs exhibited antioxidant activity and anticancer activity against HeP-G2, MCF-7 and HCT116 cell lines. Collagen-NPs assessed as an effective drug loading carrier with methotrexate (MTX), a chemotherapeutic agent.

Transcriptomics aids in uncovering the metabolic shifts and molecular machinery of Schizochytrium limacinum during biotransformation of hydrophobic substrates to docosahexaenoic acid
In this study Schizochytrium limacinum SR21 was investigated for its ability to convert oils (commercial oils with varying fatty acid composition and waste cooking oil) into ω-3 fatty acid; docosahexaenoic acid (DHA). The conversion of hydrophobic substrates to DHA can be further improved using synthetic biology tools, thereby providing a unique platform for the sustainable recycling of waste oil substrates.
