  • Richness and diversity of Conidial Fungi associated with plant debris in three enclaves of Atlantic Forest in the Caatinga biome of Brazil
    Plant Ecology and Evolution, 2018
    Co-Authors: Tasciano Dos Santos Santa Izabel, Luis Fernando Pascholati Gusmao
    Abstract:

    Background and aims – A study of richness and diversity of Conidial Fungi associated with plant debris was conducted in three Atlantic Forest enclaves in the Caatinga biome: Serra da Jibóia-BA (SJ), Serra da Ibiapaba-CE (SI) and Brejo Paraibano-PB (BP). Methods – The plant debris samples included leaves, twigs and barks and were washed in running water, incubated in moist chambers and analyzed for 40 days under a stereomicroscope. These reproductive structures were transferred to slides containing PVL resin and identified with specialized literature. Key results – The richness and diversity were similar in the three enclaves of interest. Cluster analysis using the Morisita similarity index indicated a group formed by fungal communities of SI and BP and another with SJ. Of these substrates, the leaves had the greatest richness and the bark samples had the greatest diversity, but these differences were not significant. Multivariate analysis via NMDS revealed differences in the fungal community composition with respect to the substrate and area, but the similarity analysis (ANOSIM) indicated that the differences were significant only with respect to the substrate.Conclusions – The survey data shows the great richness and diversity of Conidial Fungi in the studied areas. Substrate was the most determinant factor for the distribution of Fungi when compared with area.

  • fungal succession on plant debris in three humid forests enclaves in the caatinga biome of brazil
    Brazilian Journal of Botany, 2016
    Co-Authors: Tasciano Dos Santos Santa Izabel, Luis Fernando Pascholati Gusmao
    Abstract:

    (Fungal succession on plant debris in three humid forests enclaves in the Caatinga biome of Brazil.) Fungal succession (sequential occurrence of sporulating Fungi) was investigated on plant debris (leaves, twigs, and barks). The material was collected in three humid forests enclaves in the Caatinga biome, northeast of Brazil, and the samples were incubated in moist chambers to verify the occurrence of Conidial Fungi in four incubations periods: 1 (up to 10 days of incubation), 2 (11–20 days), 3 (21–30), and 4 (31–40 days). A total of 213 taxa were recorded. The species richness was similar in the three enclaves studied. Only two species occurred in all periods and more than one substrate: Chloridium virescens ((Pers.) W. Gams & Hol.-Jech) occurred in the leaves and barks and Ellisembia adscendens ((Berk.) Subram.) occurred in the barks and twigs. Nonmetric multidimensional scaling (NMDS) indicates that substrate was the most determinant factor for the fungal community composition compared with area and incubation periods. The result of analysis of similarity demonstrates that the groups formed in NMDS were significant. The succession on decaying leaves demonstrated the highest richness among the substrates studied. In the leaves, the major richness values were detected in the P1 period, while in the barks and twigs, the major richness values were detected in the P1 and P2 periods. Species richness decreases after 20 incubation days in all substrates. Cluster analysis indicates the formation of communities relating to incubation periods in the leaves. The results of this study demonstrated a fungal succession on plant debris during the incubation period.

  • Occurrence of Water Borne Conidial Fungi in Relation to Some Physico-Chemical Parameters in a Fresh Water Stream
    2009
    Co-Authors: S. C. Sati, Pratibha Arya
    Abstract:

    Relative effect of some physico-chemical parameters of water to the occurrence of water borne Conidial Fungi was studied in a high altitudinal fresh water stream. A total of 30 species belonging to 21 genera were isolated. The number of Conidial fungal species was enumerated in water samples collected monthly during the period of March 2007-February 2008. There was marked seasonal fluctuation in the occurrence of the species. The maximum number of species was found during spring to early summer and winter, while there was a decline in the number of species during late summer, rainy and early autumn seasons. Species richness was correlated with seven different water quality variables measured for each sample period, viz., temperature, pH, dissolved oxygen, organic and inorganic content, phosphate and sulphate concentration. The data were analyzed statistically for correlation and these factors were found to be significant for the occurrence of water borne Conidial Fungi. (Nature and Science. 2009;7(4):20-28). (ISSN: 1545-0740).

  • Utilization of various carbon sources for the growth of waterborne Conidial Fungi
    Mycologia, 2006
    Co-Authors: S. C. Sati, S. Bisht
    Abstract:

    Four isolates of waterborne Conidial Fungi (Tetracheatum elegans, Tetracladium marchalianum, Pestalotiopsis submersus and Flagellospora penicillioides) were investigated for their carbon requirement, using eight different carbon sources (viz. glucose, fructose, sucrose, xylose, starch, cellulose, dextrin and lactose). All Fungi tested grew sparsely on the basal medium lacking in carbon, which was the control. However these Fungi were found to vary in their ability to use the supplied sources of carbon. Glucose and sucrose were found to be suitable sources of carbon for all four fungal isolates, whereas fructose proved good for T. marchalianum and P. submersus. Starch and xylose also supported growth of T. marchalianum, P. submersus and F. penicillioides. Cellulose, a polysaccharide, was a poor source of carbon for the growth of these isolates. Four g/L of glucose was recorded as the most useful concentration that gives the maximum dry weight of selected Fungi (262 mg and 400 mg for T. elegans and P. submersus respectively after 15 d).

  • transfer learning approach for the classification of Conidial Fungi genus aspergillus thru pre trained deep learning models
    IEEE Region 10 Conference, 2020
    Co-Authors: Matt Ervin G Mital, Rogelio Ruzcko Tobias, Herbert V Villaruel, Jose Martin Z Maningo, Robert Kerwin C Billones, Ryan Rhay P Vicerra, Argel A Bandala, Elmer P Dadios
    Abstract:

    The Aspergillus genus is deemed relevant for distinction and classification in the field of food, agriculture and medicine. As there are harmful and useful ones, it adds to the necessity of correct classification. Categorization of this Conidial Fungi is usually done through manual microscopical procedures which apparently has a degree of subjectiveness. In order to classify Aspergillus samples faster and more accurately, technology, specifically image processing and machine learning are incorporated in this study. Pre-trained deep learning models are employed in classifying 9 kinds of Aspergillus. The methodology is generally comprised of preprocessing, deep-learning (training) and performance evaluation. Performance evaluation pertains to the validation accuracy and running times of the system after training through visual display of graphs and tabulation of acquired data. This study achieved a 93.3333% testing accuracy proving that the transferred knowledge is accurate, compatible and reliable.
