“…L-asparagin has been reported to be a good source by SAKSENA and KUMAR (1961) and KURTZ and FERGUS (1964). Nevertheless, MOSHER et al (1936), STEINBERG (1942) and BROCK (1951) found DL-valine to be of poor nutritive value for Trichophyton interdigitahy Aspergillus nigcr and Morchella esculenta respectively, while LoGKwooD et al (1936), WOLF (1949) and WOLF et al (1950) obtained only moderate growth of their organisms on alanine. Further, CHANDRA (1961) reported only poor growth of Cercosporina ricinella on glutamic acid, and DAS GUPTA and SHOME (1960) could not obtain any growth of Trichophyton rubrum on this amino acid.…”

Amino acids are considered to be the most easily assimilable metabolites. Like other organisms, fungi also utilize the majority of the amino acids as such in their amino acid pool. Recent evidences, however, indicate conversion of amino acids into ammonia before their utilization by fungi. This conversion depends upon the oxidative deamination of amino acids by oxidases which are the flavoproteins. In the present work an attempt has been made to determine the comparative efficiency and rate of consumption of some of the common ammo acids. The pathway of assimilation, however, has not been studied. The following amino acids were employed: Glycine, DL-valine, DL-a-alanine, DLphenylalanine, L-aspartic acid, L-glutamic acid, L-asparagin, L-histidine, L(-)-cystine, DL-methionine, DL-serine, DL-lysine and L( + )arginine. Materials and MethodsThe three organisms Pestalotia paiiciseta Sacc, Botryodiplodia theobromae Pav. and Colletotrichum gloeosporioides Penz., isolated from leaf spots of Nephelium litchi Camb. (PRASAD 1962), were used in the present investigations. Inoculations were made by GARRETT'S (1936) agar disc method from 7-12 days old cultures. Chemicals supplied by E.Merck or B.D.H. were used and all media were prepared in double distilled water. Glasswares exclusively of Pyrex make were used for distillation. 25 ml of sterilized media contained in 150 ml Erlenmeyer flasks served as nutrient in each case. Different amino acids were substituted singly for 3.5 g of KNOg/litre of modified ASTHANA and HAWKER'S medium A containing 10 g of glucose. All the inoculated flasks were incubated simultaneously at room temperature. The mean laboratory temperature during the period of incubation was 23 °C. pH of all media was adjusted to 6.0 as this pH was found to be the most suitable for growth of all the three pathogens. The dry weights of fungal mats of three different ages i.e. after 5, 10 and 15 days served as quantitative measure of growth. Three replicates were used for each series and their average has been taken as standard value. The dry weight results were statistically analysed. One set of 15 flasks of eadi treatment was separated for diromatographic analysis to detect the presence of various ammo acids. Circular paper chromatographie technique described by RANJAN et al. (1955) was used for this purpose. Butanol-acetic acid-water (4:1:5) was used as solvent, while 0.01 g ninhydrin dissolved in n-butanol served as spray reagent.

“…MARGOLIN (1942) also found that 1-rhamnose could only be utilised by Mucor ramannianus out of three Mucorales tried by him. BROCK (1951) is of the opinion that 6-carbon aldoses, glucose, mannose and galactose are much better utilised than their corresponding alcohols, sorbitol, mannitol, and dulcitol. It shows that the aldehydic or the reducing group of the sugar is necessary for their proper utilisation.…”

“…Uso tradicional o práctico: la población de la zona no reporta su uso. Sin embargo, los hongos del género Morchella tienen gran importancia económica y son objeto de comercialización por sus cualidades nutricionales (Brock 1951, Robbins & Hervey 1959, Robbins & Hervey 1965, Volk & Leonard 1989, Montoya et al 2003, Montoya et al 2004, Masaphy et al 2009, Hernández-Salmerón et al 2013. Se ha informado su consumo en 28 países de diferentes zonas del mundo (Boa 2004), por lo que no se descarta que en el futuro, este grupo sea utilizado en Colombia en el ámbito gastronómico y agroproductivo.…”

Se registra por primera vez al género Morchella Dill. ex Pers. (Ascomycota, Pezizales), único representante de la familia Morchellaceae para la micobiota Colombiana. El ascocarpo fue recolectado en un bosque muy húmedo premontano, en la vereda Santa Helena, municipio de Gachalá, departamento de Cundinamarca. El espécimen es descrito e ilustrado con fotografías y se aporta información sobre su distribución, ecología y sustrato de crecimiento. La identidad taxonómica del ejemplar es discutida de acuerdo al concepto morfológico tradicional establecido en la literatura micológica. Con este reporte, en Colombia el orden Pezizales queda constituido por 17 especies contenidas en 12 géneros y 7 familias.
