Diversity of fungi from mangrove sediments of Goa, India, obtained by metagenomic analysis using Illumina sequencing.

The fungal composition, abundance and diversity of the mangrove sediments from the Mandovi and Zuari estuaries, Goa, using paired-end Illumina sequencing, hitherto unexplored by a metagenomic approach, indicated that though the types of fungal phyla were similar between the two sediments, the abundance of the species was significantly different between them ( value < 0.005). Basidiomycota and Ascomycota were the two major phyla which were sub-divided into eighteen classes, families, orders, genera and species and one unassigned group in both the sediments.

Taxonomic diversity of bacteria from mangrove sediments of Goa: metagenomic and functional analysis.

The present study compared the taxonomic diversity and evaluated the functional attributes of the bacterial species from Mandovi and Zuari mangrove sediments, Goa, using paired-end amplicon sequencing of 16S rDNA and culture-based analyses, respectively. 16S rDNA sequencing revealed , and as the dominant phyla in both the sediments. However, the abundance of these phyla significantly differed between the samples.

Halophilic Aspergillus penicillioides from athalassohaline, thalassohaline, and polyhaline environments.

Aspergillus penicillioides is a true halophile, present in diverse econiches - from the hypersaline athalassohaline, and thalassohaline environments, to polyhaline systems, and in different geographical locations. Twenty seven isolates from these environments, were seen to be moderate halophiles, euryhaline in nature. They had an obligate need of a low aw and were unable to grow on a regular defined medium such as Czapek Dox Agar, as well as on varied nutrient rich agar media such as Malt Extract, Potato Dextrose and Sabouraud Agar; however, growth was obtained on all these media when amended with 10% solar salt.
