Investigation on Influence of Acetylene Enrichment in Diesel Engines Operating With Microalgae‐Waste Plastic Oil‐Heptane Fuel Mixture

Energy Science &Engineering, Volume 13, Issue 6, Page 3107-3122, June 2025.
The graphical abstract depicts biodiesel production from algae and plastic waste via oil extraction, transesterification, and pyrolysis. These fuels were tested for diesel engine performance, improve combustion, and reduce emissions. ABSTRACT This study investigates the performance and emission characteristics of a diesel engine running on a blend of ...

Ecological interactions in glacier environments: a review of studies on a model Alpine glacier

Biological Reviews, Volume 100, Issue 1, Page 227-244, February 2025.
ABSTRACT Glaciers host a variety of cold‐adapted taxa, many of which have not yet been described. Interactions among glacier organisms are even less clear. Understanding ecological interactions is crucial to unravelling the functioning of glacier ecosystems, particularly in light of current glacier retreat.

Conversion of Shrimp Aquaculture Waste Into Nutritious Floc Using Taro Flour With Varied C/N Ratios: A Sustainable Approach for Aquafeed Production

Aquaculture Research, Volume 2025, Issue 1, 2025.
Waste management is a critical challenge in the aquaculture industry, particularly in the cultivation of Pacific white shrimp (Penaeus vannamei). This study explores the potential of converting shrimp aquaculture waste into a nutritious floc biomass by incorporating taro flour as a carbon source at varying carbon‐to‐nitrogen (C/N) ratios.

Commercialization of Algae‐Based Biofuels: The Case of Ghana

International Journal of Chemical Engineering, Volume 2025, Issue 1, 2025.
Microalgae are a promising renewable energy source due to their rapid growth, high nutritional value, and minimal competition with food production. The study evaluates the feasibility of large‐scale algae‐based biofuel production in Ghana, contributing to the global shift toward sustainable energy.

Ultrastructural Perspectives on the Biology and Taphonomy of Tonian Microfossils From the Draken Formation, Spitsbergen

Geobiology, Volume 22, Issue 6, November/December 2024.
ABSTRACT Silicified peritidal carbonates of the Tonian Draken Formation, Spitsbergen, contain highly diverse and well‐preserved microfossil assemblages dominated by filamentous microbial mats, but also including diverse benthic and/or allochthonous (possibly planktonic) microorganisms. Here, we characterize eight morphospecies in focused ion beam (FIB)

Newly isolated strains of potentially microcystin-producing cyanobacteria in potable water: case study of Mawoni village, South Africa

Frontiers in Environmental Science
Toxic cyanobacterial species occur in aquatic ecosystems when favourable environmental conditions prevail. These bacteria can produce natural hepatotoxic metabolites called microcystins that can affect the quality of water. Human exposure to microcystins

Colony‐forming and single‐cell picocyanobacteria nitrogen acquisition strategies and carbon fixation in the brackish Baltic Sea

Limnology and Oceanography, Volume 69, Issue 9, Page 1955-1969, September 2024.
Abstract Picocyanobacteria are widespread and globally significant primary producers. In brackish waters, picocyanobacterial populations are composed of diverse species with both single‐cell and colony‐forming lifestyles. Compared to their marine counterparts, brackish picocyanobacteria are less well characterized and the focus of research has been ...

Phytoplankton composition of the water and gastrointestinal tract of the mussel Diplodon enno (Ortmann, 1921) from São Francisco river (Bahia, Brazil)

Brazilian Journal of Biology
The knowledge on diet composition of the freshwater mussel Diplodon enno (Ortmann) would aid in its culture and propagation allowing, this way, the replacement of natural endangered populations in Brazil.

Effects of Macrobrachium nipponense on Phytoplankton Communities and Water Environmental Factors in Macrobrachium rosenbergii Culture

Aquaculture Research, Volume 2024, Issue 1, 2024.
Excessive feed input led to eutrophication and Cyanobacterial blooms in the culture of giant freshwater prawn (GFP, Macrobrachium rosenbergii). In order to improve the water quality and control the Cyanobacterial blooms, we tried the mixed culture of oriental river prawn (ORP, Macrobrachium nipponense), which can feed on plant and organic debris.
