Application of Dry Biomass of Aphanothece sp. as A Biosorbent of Copper Heavy Metal

EduChemia, 2020
Various technologies have been developed to reduce heavy metal content in the wastewater. The biosorption method is a technique that is widely applied because it is cheap, environmentally friendly, and has high efficiency.

Growth of aphanothece microscopica nägeli on exogenous sugars

Bioscience Journal, 2011
Biological processes for wastewater treatment generally produce a lot of biomass or active sludge without reuse. In this context, incorporation of organic matter and nutrients from agro industrial effluents into cell mass for single-cell protein allowed ...

Nitrate Uptake in the Halotolerant Cyanobacterium Aphanothece halophytica is energy-dependent driven by ΔpH [PDF]

BMB Reports, 2005
The energetics of nitrate uptake by intact cells of the halotolerant cyanobacterium Aphanothece halophytica were investigated. Nitrate uptake was inhibited by various protonophores suggesting the coupling of nitrate uptake to the proton motive force.

A glimpse into darkness: Diversity of culturable cyanobacteria, green algae and fungi from subaerial cave biofilms. [PDF]

J Phycol
Abstract Caves and hypogean environments provide stable microclimates characterized by uniform temperatures, constant humidity, and low light levels. In such sites, extremely low light irradiance can support the growth of subaerial biofilms (SABs) dominated by unique photosynthetic communities of cyanobacteria accompanied by chlorophytes, heterotrophic

Diversity, Community Assemblage, and Environmental Determinants of Phytoplankton in a Subtropical Transboundary Coastal River. [PDF]

Ecol Evol
This study examined spatial and seasonal dynamics of phytoplankton communities in the Dakatia River, identifying 37 genera across six major taxonomic classes, with Bacillariophyceae being the most dominant. Seasonal peaks in phytoplankton abundance and diversity indices indicated higher richness and evenness during winter, while multivariate analyses ...

Population growth potential of rotifers from a high altitude eutrophic waterbody, Madín reservoir (State of Mexico, Mexico): The importance of seasonal sampling

Journal of Limnology, 2018
To understand the population growth potential of different species of rotifers in nature, field collections through seasons are essential. We sampled zooplankton (and measured selected physicochemical variables) from the Madín reservoir, a high altitude ...

Identification of Cyanobacteria in a Eutrophic Coastal Lagoon on the Southern Baltic Coast

Frontiers in Microbiology, 2017
Cyanobacteria are found worldwide in various habitats. Members of the picocyanobacteria genera Synechococcus and Prochlorococcus dominate in oligotrophic ocean waters. Other picocyanobacteria dominate in eutrophic fresh or brackish waters. Usually, these

Crosstalk between biological and chemical diversity with cytotoxic and cytostatic effects of Aphanothece halophytica in vitro

Anais da Academia Brasileira de Ciências, 2022
Different solvent extracts from Aphanothece halophytica (A. halophytica) were evaluated for their cytotoxic effects against four human cancer cell lines. The samples demonstrated different percentages of cyanobacteria species populations.

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments. [PDF]

FEBS Open Bio
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.
