Marine phytoplankton diversity of Odisha coast, India with special reference to new record of diatoms and dinoflagellates

Abstract

The eastern part of Odisha is the coastal line covering the districts from Ganjam to Balasore. In the present investigation, a total 54 phytoplankton species under 30 genera were reported from different sites of east coast Odisha. The diversity of phytoplankton included three divisions such as Chlorophyta (02 species), Bacillariophyta (42 species) and Dinophyta (10 species).

A state-of-the-art review on fucoidan as an antiviral agent to combat viral infections

“…The fresh and marine ecosystems are rich in biodiversity and hold a potential source of sulfated polysaccharides ( Behera et al, 2020 ; Behera et al, 2021 ; Dash et al, 2020 ; Dash et al, 2021 ; Maharana et al, 2019 ; Pradhan, Maharana, Bhakta, & Jena, 2021 ; Pradhan, Patra, Behera, et al, 2020 ; Pradhan, Patra, Dash, et al, 2021 ). Algae-derived sulfated polysaccharides such as fucoidan have potentially been used as an antiviral agent ( Pagarete et al, 2021 ; Pradhan, Bhuyan, et al, 2022 ; Pradhan, Nayak, et al, 2022 ; Pradhan, Patra, Nayak, et al, 2020 ).…”

Toxic Effects and Tumor Promotion Activity of Marine Phytoplankton Toxins: A Review

“…One of the most important components of marine ecosystems is phytoplankton [1], and because of their photosynthetic activities, they play an important role as the principal source of biomass and organic molecules in oceans [20,21]. In contrast, many phytoplankton species produce secondary bioactive metabolites, including poisonous toxins [22][23][24][25].…”

“…Phytoplankton, typically found in aquatic systems, are microscopic, unicellular organisms that exist solitarily or in chains and are photosynthetic. The activities of freshwater and marine water Cyanobacteria, diatoms, and dinoflagellates may account for almost half of the global CO 2 fixation [1][2][3][4][5][6]. However, some phytoplankton can multiply rapidly to form harmful algal blooms (HABs), and some even produce toxins that harm marine life and humans.…”

Cyanobacteria and Algae-Derived Bioactive Metabolites as Antiviral Agents: Evidence, Mode of Action, and Scope for Further Expansion; A Comprehensive Review in Light of the SARS-CoV-2 Outbreak

“…In this regard, the screening of compounds extracted from natural sources could yield new structures able to interact strongly with the virus, thus inhibiting it. The marine ecosystem is the most biodiverse ecosystem [ 4 ] and it can provide a variety of bioactive metabolites. Algae-derived bioactive metabolites have been shown to have several potential therapeutic effects, including antiviral activity [ 5 , 6 ].…”
