Abstract

Ample quantities of a crepidotoid agaric were collected from an evergreen forest in Kerala State, India and subsequent morphological and molecular analysis based on nLSU sequence confirmed it as Conchomyces bursiformis. A reappraisal along with comprehensive description, photographs, and discussion of this rare monotypic agaric is provided.

Abstract

This study aimed to assess protein enrichment of sterile and non-sterile cassava pulp using four strains of Aspergillus niger – AN1, AN2, AN3, AN4. First, studies were conducted to evaluate nutritional requirements of A. niger strains and their suitability for protein enrichment of cassava pulp. Second, sterile and non-sterile cassava pulps were inoculated with spores of A. niger strains and incubated under conditions of solid-state fermentation for 8 days using standard methods. Protein contents of sterile and non-sterile cassava pulps were determined by the Kjeldahl method. Initial nutritional requirements studies showed that A. niger strains grew at rates between 2.0 cm and 8.5 cm over 10 days on potato dextrose agar medium of different pH. The dry weight of mycelia of A. niger strains varied in liquid media separately supplemented with different concentrations of thiamine, ammonium nitrate and sodium chloride. A. niger strains also showed different levels of sporulation when cultured in growth media supplemented with different concentrations of sodium chloride. Increases in protein contents of sterile cassava pulp by AN1, AN2, AN3 and AN4 were 15.65%, 22.61%, 18.30% and 19.13%, respectively. On non-sterile cassava pulp, the increases in protein content by AN1, AN2, AN3 and AN4 were 15.40%, 21.54%, 10.80% and 3.85%, respectively. A. niger strain AN2 was the most suitable strain for the enrichment of protein content of cassava because it sparsely produced spores, it had the highest mycelial growth and resulted in the greatest increase in protein content of both sterile and non-sterile cassava pulp.

Abstract

Studies on fungal species consortia of manglicolous fungi are very few. Observations of fungal species consortia may provide an idea on the fungal community structures and help in understanding ecosystem dynamics. In this paper, the fungal species consortia recorded on Nypa fruticans at Brunei is presented. Astrosphaeriella striatispora, Linocarpon appendiculatum, L. bipolaris, Neolinocarpon globosicarpa, Oxydothis nypae and Trichocladium nypae, were the frequently recorded fungi in this study. Three distinct fungal assemblages were found. One of these assemblages was typified by Astrosphaeriella striatispora, Linocarpon nypae and Oxydothis nypae in which the fungi occurred both in association with others as well as singly indicating a commensalistic occurrence. The second assemblage, was characterized by Linocarpon appendiculatum and Linocarpon bipolaris, the fungi occurred almost only in association with others, indicating a mutualistic behavior. The third assemblage was characterized by Anthostomella eructans, Anthostomella sp. and Trichocladium sp. which always occurred singly, indicating a possible antagonistic life style but the percentage occurrence of the last group was far low to attribute any antagonistic potential of these fungi in preventing other fungi from colonization.
