Polyenes were, after griseofulvin, the first fungal-specific antibiotics on the market and ever since, more than 200 polyene antifungals have been discovered, of which amphotericin B, nystatin and natamycin are most commonly used in antifungal therapy .

Lignocellulosic biomass (LC biomass)

Bioenergy represents energy from biomass and plays an important role in promoting renewable alternatives. LC biomass is one of the most generous renewable bioresources in nature containing lignin, cellulose, and hemicelluloses. Lignocellulosic materials are the best sources used for biofuel production, such as biogas, and include residues from agriculture and forests, energy crops, and municipal and food waste. According to the latest statistical report for biogas, in Europe, almost 72% of the feedstocks used in the anaerobic digestion (AD) process for biogas production come from the agricultural sector, such as energy crops, manure, and other agricultural residues. The main issue of using lignocellulosic (LC) biomass for the biogas production is biomass recalcitrance, which represents biomass resistance to chemical and biological breakdown.

Micro-Algal Biotechnology

Environment is everything including both the living and non living things in the earth’s ecosystem. Today the pollution of the environment is a serious concern facing humanity and other life forms in the world. The environment is daily polluted by natural and anthropogenic (man-mad) factors due to inattention and improper use of the existing science and technology. Several physicochemical methods are used for protection of the pollution in the environment but these techniques have its own advantage and disadvantage. In recent years, using biological methods specially, microalgae for environmental pollution protection is the best one, because it is suitable, produce less and or non toxic products, cost effective and eco-friendly methods to our environment. Microalgae are the important groups of living organisms used for biotechnological utilizations such as for environmental protection, Agricultural usage, biofule production, pharmaceutical production etc. without any environmental factor. This review focuses on the environmental applications of micro-algal biotechnology for treatment of wastewater nutrients, removal of heavy metals from the natural water, mitigation of CO2, removal of dyes and dyestuffs from their effluents and their agricultural usage without any factor in the natural environment.

Lichen as Multipartner Symbiotic Relationships

Lichens have long been considered as composite organisms composed of algae and/or cyanobacteria hosted by a fungus in a mutualistic relationship. Other organisms have been gradually discovered within the lichen thalli, such as multiple algal species, yeasts, or even viruses. Of pivotal relevance is the existence of the lichen microbiome, which is a community of microorganisms that can be found living together on the lichen surface. This community performs a growing number of functions. In this entry, we explore the journey of lichens being considered from a dual partnership to a multi-species symbiotic relationship.

Biocontrol Agents

Biocontrol agents (BCAs) are living organisms and their derivatives that act against plant diseases and pests via direct antagonistic effects but also indirectly via the induction of plant resistance. They have been proposed as an alternative to standard fungicides but their disease management capacity is usually incomplete and heavily relies on uncontrollable environmental conditions. An integrated approach of combining BCAs with fungicides can reduce the fungicide doses to manage plant diseases and thereby their residual effects that affect the environment and human health.

Aging and Its Molecular Mechanism

Aging is a continuous process over time that is mainly related to natural alterations in mechanical–biological processes. This phenomenon is due to several factors, including the time and energy of biological processes. Aging can be attributed to biological factors such as oxidative stress, cell longevity, and stem cell senescence.

Dromaeosauridae

Dromaeosauridae (/ˌdrɒmi.əˈsɔːrɪdiː/) is a family of feathered theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous Period. The name Dromaeosauridae means 'running lizards', from Greek δρομεῦς (dromeûs), meaning 'runner', and σαῦρος (saûros), meaning 'lizard'. In informal usage, they are often called raptors (after Velociraptor), a term popularized by the film Jurassic Park; a few types include the term "raptor" directly in their name and have come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia, South America and Antarctica, with some fossils giving credence to the possibility that they inhabited Australia as well. They first appeared in the mid-Jurassic Period (late Bathonian stage, about 167 million years ago) and survived until the end of the Cretaceous (Maastrichtian stage, 66 ma), existing until the Cretaceous–Paleogene extinction event. The presence of dromaeosaurids as early as the Middle Jurassic has been suggested by the discovery of isolated fossil teeth, though no dromaeosaurid body fossils have been found from this period.

In biology, the electric organ is an organ common to all electric fish used for the purposes of creating an electric field. The electric organ is derived from modified nerve or muscle tissue. The electric discharge from this organ is used for navigation, communication, mating, defense and also sometimes for the incapacitation of prey.
