Abstract Cyanobacteria are photosynthetic prokaryotes. They exhibit remarkable metabolic adaptability, enabling them to withstand oxidative stress, high salinity, temperature extremes, and UV radiation (UVR). Their adaptive strategies involve complex regulatory networks that affect gene expression, enzyme activity, and metabolite fluxes to maintain cellular homeostasis. Key stress response systems include the production of antioxidants such as peroxidases (POD), catalase (CAT), and superoxide dismutase (SOD), which detoxify reactive oxygen species (ROS). To withstand environmental stresses, cyanobacteria maintain osmotic balance by accumulating compatible solutes, such as glycine betaine, sucrose, and trehalose. They also adapt to temperature and light fluctuations… More >

Abstract Soil naturally contains various heavy metals, however, their concentrations have reached toxic levels due to excessive agrochemical use and industrial activities. Heavy metals are persistent and non-biodegradable, causing environmental disruption and posing significant health hazards. Microbial-mediated remediation is a promising strategy to prevent heavy metal leaching and mobilization, facilitating their extraction and detoxification. Nickel (Ni), being a prevalent heavy metal pollutant, requires specific attention in remediation efforts. Plants have evolved defense mechanisms to cope with environmental stresses, including heavy metal toxicity, but such stress significantly reduces crop productivity. Beneficial microorganisms play a crucial role in… More > Graphic Abstract

Abstract Microalgae are mostly photoautotrophic microscopic organisms. According to their cellular structure, they are classified into two types, eukaryotes, and prokaryotes, and they are distributed in all types of ecosystems, presenting unique qualities due to the fact that they synthesize high value-added molecules used in various productive and environmental activities, and because their biomass is used as raw material to obtain various products. Therefore, the objective of this review was to collect, organize, and collate current information on the use of microalgae in the development of biotechnology involving the areas of agriculture, health, food, bioremediation, and More >

Abstract The use of agricultural straw for algal bloom control has been studied for more than 30 years. In this article, we have reviewed the promising potentials of using agricultural straw as source of anti-algal agents, including the effectiveness of each major straw type so far used in this regard, and the investigated algal species. Various pre-treatment methods have also been widely reviewed. Signifi- cant progress has been made in natural product chemistry and molecular biology with regards to agricultural straw, especially in relation to the extraction of antialgal allelochemicals, degradation processes of agricultural straws and More >
