Secondary metabolism is intrinsically linked to primary metabolism which directly controls basic cellular traits such as the uptake and secretion of macromolecules. Filamentous fungi have been described to produce a great variety of volatile metabolites belonging to saturated hydrocarbons alcohols aldehydes ketones lactones linear esters ethers phenols and terpenoids.
Fungi are important to everyday human life.
Primary metabolism of fungi. Filamentous fungi are important industrial cell factories used for the production of a wide range of enzymes and metabolites. Their primary metabolism is a significant source of industrially important compounds as well as of monomeric building blocks for the production of secondary metabolites and extracellular enzymes. Secondary metabolism is intrinsically linked to primary metabolism which directly controls basic cellular traits such as the uptake and secretion of macromolecules.
In fungi this secretory activity exports the machinery required for nutrient acquisition hydrolysis and uptake. Nevertheless also a vast array of secondary metabolites SM which are of great interest for. The most widely known fungal metabolite is the antibacterial agent penicillin.
The endophytic properties of fungi are both advantageous and disadvantageous as they can provide necessary nutrients to the plants as well as cause deleterious effects as they utilize the plants machinery to produce secondary metabolites. Filamentous fungi are important industrial cell factories used for the production of a wide range of enzymes and metabolites. Their primary metabolism is a significant source of industrially important compounds as well as of monomeric building blocks for the production of secondary metabolites and extracellular enzymes.
Fungi are important primary decomposers of organic material as well as amazing chemical engineers synthesizing a wide variety of natural products some with potent toxic activities including antibiotics and mycotoxins. In fungal genomes the genes involved in these metabolic pathways can be physically linked on chromosomes forming gene clusters. Primary metabolism affects all phenotypical traits of filamentous fungi.
Particular examples include reacting to extracellular stimuli producing precursor molecules required for cell division and morphological changes as well as providing monomer building blocks for production of secondary metabolites and extracellular enzymes. In contrast to genes that are required for the synthesis of a primary metabolite that are dispersed throughout the fungal genome the genes encoding the enzymatic activities to. Primary metabolites are considered essential to microorganisms for proper growth.
Secondary metabolites do not play a role in growth development and reproduction and are formed during the end or near the stationary phase of growth. Secondary metabolites are structurally heterogenic low-molecular-mass molecules produced by many microorganisms especially soil-dwelling bacteria and fungi. Unlike primary metabolites these.

Some of the solid substrates utilized by fungi are dead and decaying material including herbivore dung saprophytic and coprophilous fungi live plants endophytic parasitic and mycorrhizal fungi lichens lichenicolous and endolichenic fungi and insects entomopathogenic fungi. Many Fungi have a well-developed secondary metabolism. The diversity of fungal species and the diversification of biosynthetic gene clusters underscores a nearly limitless potential for metabolic variation and an untapped resource for drug discovery and synthetic biology.
Much of the ecological success of the filamentous fungi in colonizing the planet is owed to their ability to deploy their secondary metabolites. As heterotrophs fungi require organic compounds for both synthesis of biomass anabolic metabolism and production of energy to drive these reactions catabolic metabolism. These aspects are referred to as primary metabolism.

Fungi are not obvious in the way large animals or tall trees appear. Yet like bacteria they are the major decomposers of nature. With their versatile metabolism fungi break down organic matter which would not otherwise be recycled.
Fungi are important to everyday human life. Filamentous fungi have been described to produce a great variety of volatile metabolites belonging to saturated hydrocarbons alcohols aldehydes ketones lactones linear esters ethers phenols and terpenoids.
