Aquatic macrophytes are aquatic photosynthetic organisms, large enough to see with the naked eye, that actively grow permanently or periodically submerged below, floating on, or growing up through the water surface. Aquatic macrophytes play an important role in the structure and function of aquatic ecosystems and certain macrophytes species are cultivated for human consumption, yet several of the worst invasive weeds in the world are aquatic plants. Many of the threats to fresh waters (e.g., climate change, eutrophication) will result in reduced macrophytes diversity and will, in turn,...

Cyanobacteria have great potential in serving the humanity in many ways. The diazotrophic nature, wide distribution pattern and capability to enter into N fixing symbiosis of BGA make them very attractive for research. In Agriculture, Cyanobacteria has a long history of usage in the form of biofertilizers. Other major applications of cyanobacteria in diverse fields of human welfare such as food and animal feed, in bioremediation of toxic compounds, in biocontrol of pests, production of commercial and laboratory chemicals, restriction enzymes, pharmacological tools (Patterson, 1996)and...

Algae are simple autotrophic organisms and from simple inorganic molecules such as carbon dioxide they produce complex organic compounds using energy from light or inorganic chemical reactions. Although algae grows at a fast rate and good producers of lipids in comparison to other oil sources, harvesting the algae and extracting the lipids is a challenge to the commercial- scale development of algae.Algal biofuels offer great promise in contributing to the growing global demand for alternative sources of renewable energy. However, to make algae- based fuels cost competitive with petroleum,...

In der heutigen Landwirtschaft haben chemische Düngemittel die Fruchtbarkeit des Bodens verringert, so dass er sich nicht mehr für den Anbau von Kulturpflanzen eignet. Darüber hinaus hat der übermäßige Einsatz dieser Mittel zu schwerwiegenden Gesundheits- und Umweltrisiken geführt, wie z. B. Bodenerosion, Wasserverschmutzung, Pestizidvergiftung, Absinken des Grundwasserspiegels, Vernässung und Verarmung der Artenvielfalt. Biodünger aktiviert spontan die im Boden vorhandenen Mikroorganismen auf wirksame und umweltfreundliche Weise und gewinnt dadurch an Bedeutung für den Einsatz in...

Dans les pratiques agricoles actuelles, les engrais chimiques ont réduit la fertilité des sols, les rendant impropres à la culture. En outre, l'utilisation excessive de ces intrants a également entraîné de graves dangers pour la santé et l'environnement, tels que l'érosion des sols, la contamination de l'eau, l'empoisonnement par les pesticides, la baisse de la nappe phréatique, l'engorgement des sols et l'appauvrissement de la biodiversité. Les biofertilisants activent spontanément les micro-organismes présents dans le sol d'une manière efficace et respectueuse de...

In current agriculture practices, chemical fertilizers have reduced the fertility of soil, making it unsuited for raising crop plants. Additionally, the excessive use of these inputs has also led to severe health and environmental hazards such as soil erosion, water contamination, pesticide poisoning, falling ground water table, water logging and depletion of biodiversity. Biofertilizers spontaneously activates the microorganisms found in the soil in an effective and eco-friendly way, thereby gaining more importance for utilization in crop production, restoring the soils fertility and...
