Exploring the dynamics of algae-associated microbiome during the scale-up process of Tetraselmis sp. microalgae: A metagenomics approach.

Microalgae have become a key source of valuable compounds, promoting commercial scale applications. However, biological contamination is one of the most critical problems associated with large scale algal production, especially in open systems such as raceway ponds. The current research is the first to assess the effectiveness of open raceway ponds in maintaining a pure culture of Tetraselmis sp.

Asterarcys quadricellulare (Chlorophyceae) protects H9c2 cardiomyoblasts from HO-induced oxidative stress.

Oxidative stress has recently been identified as an important mediator of cardiovascular diseases. The need to find efficient antioxidant molecules is essential in the disease's prevention. Therefore, the present study aimed to evaluate the potential of microalgae bioactive in protecting H9c2 cardiomyoblasts from HO-induced oxidative stress.

Evaluation of sp. Extract on Bell Pepper ( L.) Yield and Quality in a Hydroponic Greenhouse System.

This study was carried out to investigate the impacts of cyanobacteria ( sp.) high-value product extract (HVPE) and water resuspended biomass WRB treatments on bell pepper production using the hydroponic system under greenhouse conditions. Six cyanobacteria treatments (6 ml L, 4 ml L, and 2 ml L - HVPE, 6 ml L, 4 ml L, and 2 ml L - WRB, and TR0 as control) were evaluated using the foliar application method.

Microalgal-based feed: promising alternative feedstocks for livestock and poultry production.

There is an immediate need to identify alternative sources of high-nutrient feedstocks for domestic livestock production and poultry, not only to support growing food demands but also to produce microalgae-source functional foods with multiple health benefits. Various species of microalgae and cyanobacteria are used to supplement existing feedstocks. In this review, microalgae have been defined as a potential feedstock for domestic animals due to their abundance of proteins, carbohydrates, lipids, minerals, vitamins, and other high-value products.

Sustainable Food Production and Nutraceutical Applications from Qatar Desert sp. (Chlorophyceae).

Microalgae isolated from the Qatari desert was identified as thermotolerant, with a rich metabolite profile that is appropriate for use as food and health supplements. In this research, a species of , QUCCCM3, from the Qatar University Culture Collection of Cyanobacteria and Microalgae, was investigated for its growth characteristics and metabolite compositions for use as potential feedstock for food production. The strain was cultivated at 30, 35, and 40 °C, covering the annual average low and high temperatures in Qatar.

Algae-Derived Bioactive Compounds with Anti-Lung Cancer Potential.

Lung cancer is one of the major causes of death worldwide. Natural molecules with anti-lung cancer potential are of a great interest and considered as very promising alternative to substitute or enhance the efficiency of the conventional drugs. Recently, algae as source of high value-added compounds are considered as very promising source of these bioactive molecules.

Toxicity, activation process, and histopathological effect of Bacillus thuringiensis vegetative insecticidal protein Vip3Aa16 on Tuta absoluta.

Tuta absoluta is a destructive moth of Solanaceae plants and especially tomatoes. Here, we considered the entomopathogenic activity of the Bacillus thuringiensis Vip3Aa16 protein heterologously produced by Escherichia coli against T. absoluta.

Screening and identification of a Bacillus thuringiensis strain S1/4 with large and efficient insecticidal activities.

The bacterium Bacillus thuringiensis was recognized for its entomopathogenic activities related to Cry and Cyt proteins forming the δ-endotoxins and some extracellular activities like the vegetative insecticidal proteins (VIP) and Cry1I. These activities may act specifically against diverse organisms and some of them typically characterize each strain. Here, we screened a set of 212 B.
