    for laccase production by a novel deuteromycete fungus Myrothecium Verrucaria NF using response surface methodology. Int Conf Civil Mater Environ Stud – doi: /. The reproduction by means of small spores is a cornerstone in the ecology of fungi. Although a single spore may have a negligible chance of reaching a suitable substrate, spores may be produced in such quantities that even discrete substrates can be exploited by the species as a whole.

    INTRODUCTION. Plant pathogens produce a range of enzymes capable of degrading plant cell wall components (1,23). Among the economically important plant pathogens, Myrothecium verrucaria (Albertini and Schwein) Ditmar:Fr, is a ubiquitous phytopathogenic fungus which attacks a wide range of plants, including cucumber (20), soybean (16), upland cotton (11), sunflower (3), birdsfoot trefoil (6. The fungus employed (Myrothecium verrucaria) has been studied mostly in relation to its cellulose degrading ability, but this report will be concerned only with non-cellulosic substrates. The strain used (USDA ) was found by White et al. () to be among the most strongly cellulolytic of a series of about cultures representing 45 genera of.

An interesting example of this was a study where extracted grape waste material and pressed apple pulp were tested as carbon sources for growing Penicillium funiculosum, Myrothecium verrucaria and Aspergillus niger, with the aim of producing cellulolytic enzymes (Kuzmanova et al., ).

Crude protein (35%) and a high level of cellulase. Studies on the physiology of spores of the cellulolytic fungus Myrothecium verrucaria, By Gabriel Raphael Mandels and Anna B. Norton.

Greatest effects were caused by azide (fold at μm) and by 2,4-dinitrophenol (7-fold at μm). Marked stimulation was also caused by 10 μm silver (5-fold), 30 μm pentachlorophenol (6-fold), 10 μm carbonyl cyanide m Cited by: 7.

Abstract. The verrucarins and roridins are secondary metabolites of the soil fungi Myrothecium verrucaria (Albertini et Schweinitz) Ditmar ex Fries and Myrothecium roridum Tode ex Fries.

The species Myrothecium belongs to the fungi imperfecti, order of Moniliales, family Tuberculariaceae (30, 17, 32).The distinction between these and other closely related fungal species is difficult.

Myrothecium verrucaria, Aspergillus Penicillium sp. can grow also at a relative humidity of %. Most often, the first affected are book bindings since they take up air humidity.

Some filamentous fungi frequently associated with paper degradation are able to hydrolyze cellulose fibers owing to their cellulolytic enzymatic system. Herbicides and spray adjuvants were evaluated for compatibility with the bioherbicidal fungus, Myrothecium verrucaria.

Several commercial formulations of glyphosate were found to be compatible for tank mixing with M. verrucaria, including Touchdown® and RoundUp HiTech®.

Others, such as Accord XRT II® and RoundUp WeatherMAX® killed all the spores of M. verrucaria immediately after. Studies were conducted on a fungi Myrothecium verrucaria (MV) strain, originally isolated from sicklepod (Senna obtusifolia L.), that exhibits bioherbicidal activity against kudzu fPueraria lobata.

THE INVERTASE OF MYROTHECIUM VERRUCARIA SPORES' G. Mandels IN THE COURSE of studies on the germination and respiration of spores of Myrothecium verrucar-ia it was found that they had considerable invertase ac-tivity (Mandels and Norton, ). The ease with which the conidia of this fungus can be raised and.

Dormancy in fungus spores can be due to a variety of causes relating to structural, physiological, or biochemical functions.

Based on data reported here and earlier, compartmentation of endogenous reserves or of enzymes is proposed as the mechanism controlling dormancy in spores ofMyrothecium verrucaria andTrichoderma reesei.

Spores of both organisms contain a pool(s) of. Suspensions of organisms obtained by centrifuging strained rumen liquor from sheep hydrolysed the different forms of cellulose tested. It was found possible to obtain freeze-dried preparations, and from these acetone powders, which exhibited cellulolytic activity.

Cultures were prepared by inoculating a medium of yeast extract, cellulose and mineral salts with a concentrated suspension of rumen. The present study was undertaken to determine the possible relationship of this type of enzyme inactivation to the physiology of the cellulolytic fungus, Myrothecium verrucaria, USDA Experimental The susceptibility of to photoinactivation in the presence of was demonstrated by exposing a dilute solution of Difco (1: ) in M KH.

Fungal spores are important in the identification of the fungus, since the spores are unique in shape, color, and size. A single spore is capable of germinating and reestablishing the entire mycelium. Spores are also the method for spreading fungi in the environment.

Options for control of northern root-knot nematode (NRKN, Meloidogyne hapla) on vegetables are very limited currently. In this study, we characterized the parasitism of Myrothecium verrucaria strain X, a new nematophagous fungus, on NRKN at the stages of eggs, J2, and adult females and evaluated its biocontrol efficacy in the greenhouse.
