Trichoderma Songyi
''Trichoderma songyi'' is a species of fungus in the family Hypocreaceae. It is a soil-inhabiting fungus that associates with the pine mushroom, ''Tricholoma matsutake''. Close relatives include '' Trichoderma koningii'' and '' T. caerulescens'', from which ''T. songyi'' can be distinguished by differences in growth rate, the morphology of agar Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori (''Gracilaria'') and "tengusa" (''Gelidiaceae''). As found in nature, agar is ...-grown cultures, and an odor similar to coconuts.

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypocreaceae
The Hypocreaceae are a family (biology), family within the class Sordariomycetes. Species of Hypocreaceae are usually recognized by their brightly colored, perithecial Ascocarp, ascomata, typically yellow, orange or red. The family was proposed by Giuseppe De Notaris in 1844. According to the ''Dictionary of the Fungi'' (10th edition, 2008), the family has 22 genera and 454 species. Genera *''Acrostalagmus'' *''Aphysiostroma'' *''Cladobotryum'' *''Gliocladium'' *''Hypocrea'' *''Hypocreopsis'' *''Hypomyces'' *''Mycogone'' *''Podostroma'' *''Protocrea'' *''Rogersonia'' *''Sarawakus'' *''Sepedonium'' *''Sphaerostilbella'' *''Sporophagomyces'' *''Stephanoma'' *''Trichoderma'' References {{Taxonbar, from=Q3144255 Hypocreaceae, Ascomycota families Taxa named by Giuseppe De Notaris Taxa described in 1844 ...

Tricholoma Matsutake
, ''Tricholoma matsutake'', is a species of choice edible mycorrhizal mushroom that grows in East Asia, Europe, and North America. It is prized in Japanese cuisine for its distinct spicy-aromatic odor. Etymology The common name and specific epitaph, ''matsutake'', in use since the late 19th century, derives from Japanese ''matsu'' (pine tree) and ''take'' (mushroom). Habitat and distribution Matsutake mushrooms grow in East Asia, Southeast Asia (Bhutan and Laos), parts of Europe such as Estonia, Finland, Norway, Poland, Sweden, and along the Pacific coasts of Canada and the United States. Matsutake mushrooms grow under trees and are usually concealed under litter on the forest floor, forming a symbiotic relationship with roots of various tree species. In Korea and Japan, matsutake mushrooms are most commonly associated with ''Pinus densiflora''. Similar species In Japan, several closely related species have been found, including ''Tricholoma bakamatsutake'' (''baka-matsu ...

Trichoderma Koningii
''Trichoderma koningii'' is a very common soil dwelling saprotroph with a worldwide distribution. It has been heavily exploited for agricultural use as an effective biopesticide, having been frequently cited as an alternative biological control agent in the regulation of fungi-induced plant diseases. They are endosymbionts associated with plant root tissues, exhibiting mycoparasitism and promoting plant growth due to their capacity to produce different secondary metabolites. ''Trichoderma koningii'' is a species belonging to the genus ''Trichoderma''. Fungi in this genus are able to adapt to different ecological niches and can colonize their habitats effectively, allowing them to be powerful antagonists and biocontrol agents. Typical of ''Trichoderma'' species is having a fast growth rate and the production of green or hyaline conidia on a branched conidiophore structure. History and taxonomy ''Trichoderma koningii'' was first described by the Dutch mycologist Oudemans in 1902 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichoderma Caerulescens
''Trichoderma'' is a genus of fungi in the family Hypocreaceae that is present in all soils, where they are the most prevalent culturable fungi. Many species in this genus can be characterized as opportunistic avirulent plant symbionts. This refers to the ability of several ''Trichoderma ''species to form mutualistic endophytic relationships with several plant species. The genomes of several ''Trichoderma'' species'' ''have been sequenced and are publicly available from the JGI. Taxonomy The genus was described by Christiaan Hendrik Persoon in 1794, but the taxonomy has remained difficult to resolve. For a long time, it was considered to consist of only one species, '' Trichoderma viride'', named for producing green mold. Subdivision In 1991, Bissett divided the genus into five sections, partly based on the aggregate species described by Rifai: *''Pachybasium'' (20 species) *''Longibrachiatum'' (10 species) *''Trichoderma'' *''Saturnisporum'' (2 species) *''Hypocreanum' ...

Exponential Growth
Exponential growth is a process that increases quantity over time. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself. Described as a function, a quantity undergoing exponential growth is an exponential function of time, that is, the variable representing time is the exponent (in contrast to other types of growth, such as quadratic growth). If the constant of proportionality is negative, then the quantity decreases over time, and is said to be undergoing exponential decay instead. In the case of a discrete domain of definition with equal intervals, it is also called geometric growth or geometric decay since the function values form a geometric progression. The formula for exponential growth of a variable at the growth rate , as time goes on in discrete intervals (that is, at integer times 0, 1, 2, 3, ...), is x_t = x_0(1+r)^t where is the value of at ...

Agar
Agar ( or ), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from ogonori (''Gracilaria'') and "tengusa" (''Gelidiaceae''). As found in nature, agar is a mixture of two components, the linear polysaccharide agarose and a heterogeneous mixture of smaller molecules called agaropectin. It forms the supporting structure in the cell walls of certain species of algae and is released on boiling. These algae are known as agarophytes, belonging to the Rhodophyta (red algae) phylum. The processing of food-grade agar removes the agaropectin, and the commercial product is essentially pure agarose. Agar has been used as an ingredient in desserts throughout Asia and also as a solid substrate to contain culture media for microbiological work. Agar can be used as a laxative; an appetite suppressant; a vegan substitute for gelatin; a thickener for soups; in fruit preserves, ice cream, and other desser ...

Microbiological Culture
A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions. Microbial cultures are foundational and basic diagnostic methods used as a research tool in molecular biology. The term ''culture'' can also refer to the microorganisms being grown. Microbial cultures are used to determine the type of organism, its abundance in the sample being tested, or both. It is one of the primary diagnostic methods of microbiology and used as a tool to determine the cause of infectious disease by letting the agent multiply in a predetermined medium. For example, a throat culture is taken by scraping the lining of tissue in the back of the throat and blotting the sample into a medium to be able to screen for harmful microorganisms, such as ''Streptococcus pyogenes'', the causative agent of strep throat. Furthermore, the term culture is more generally used informally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
