Última Geastrum trichiferum and Geastrum setiferum (Geastrales, Phallomycetidae) new records for Argentina Boletín de la Sociedad Castiglia,Valeria; Cinto,Isabel; Papinutti,Leandro. In the present study two new records of Geastrum are reported for Argentina: G. trichiferum Rick and G. setiferum Baseia. Descriptions, comments and illustrations of basidiomata are given.

Ano: 2013 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1851-23722013000300001 Changes in hyphal morphology due to chitosan treatment in some fungal species BABT Oliveira Junior,Enio Nazaré de; Melo,Itamar Soares de; Franco,Telma Teixeira. In this work, changes in the hyphal morphology due to chitosan treatment in some fungal species were studied. Scanning electron microscope (SEM) observations revealed that chitosans with molar fraction of acetyl groups (F A 0.16 and 0.18) and degree of polymerization (DP 1,089 and 1,242) had a direct effect on the morphology of the chitosan-treated fungi, reflecting its potential for causing a delay in the growth of Alternaria alternata (500 µg × mL-1), Botrytis cinerea (1,000 µg × mL-1), Penicillium expansum (1,000 µg × mL-1) and Rhizopus stolonifer (500 µg × mL-1). Mycelial aggregation and structural changes such as excessive branching, swelling of the cell wall and hyphae size reduction were observed in the micrographs.

Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132012000500001 Growth rate inhibition of phytopathogenic fungi by characterized chitosans BJM Oliveira Junior,Enio N.; Gueddari,Nour E. El; Moerschbacher,Bruno. M.; Franco,Telma T.. The inhibitory effects of fifteen chitosans with different degrees of polymerization (DP) and different degrees of acetylation (F A) on the growth rates (GR) of four phytopathogenic fungi (Alternaria alternata, Botrytis cinerea, Penicillium expansum, and Rhizopus stolonifer) were examined using a 96-well microtiter plate and a microplate reader. The minimum inhibitory concentrations (MICs) of the chitosans ranged from 100 µg × mL-1 to 1,000 µg × mL-1 depending on the fungus tested and the DP and F A of the chitosan. The antifungal activity of the chitosans increased with decreasing F A. Chitosans with low F A and high DP showed the highest inhibitory activity against all four fungi. P. expansum and B. cinerea were relatively less susceptible while A.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Chitosan; Antifungal activity; Fungal morphology; Phytopathogenic fungi. Ano: 2012 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822012000200046 Influence of buffer systems on Trichoderma reesei Rut C-30 morphology and cellulase production Electron. J. Biotechnol. Ferreira,Susana M. P.; Duarte,Ana P.; Queiroz,João A.; Domingues,Fernanda C.. The cellulase enzyme production is a key issue in the enzymatic hydrolysis of lignocellulosic materials. Since fungal morphology influences the productivity of fungal fermentations, it is of major importance to well know the fungal behavior during culture for cellulase production. In this work, the influence of medium supplementation, with different buffer systems at two different concentrations and pH conditions, on the morphology of T. reesei Rut C-30 and cellulase production, was investigated. A medium without buffer was used as control. The results suggest that fungal morphology is significantly dependent on the addition of different buffer systems to the nutrient broth. The mycelial morphology shows a clear transition from clumped to pelleted forms in...
