Summary: The study found that culturing benthic diatom Haslea ostrearia in a conventional mixed PBR can overcome culture mass transfer limitation and increase photosynthesis-related kinetics by increasing dissolved inorganic carbon concentration and silica enrichment. Additionally, a fed-batch strategy on Si-P supply led to an increase in biomass productivity, while nutrient-limited conditions resulted in higher extracellular marennine productivity under different nutrient deprivations. The effect of light availability on biomass and extracellular marennine production kinetics was also investigated, showing a direct relation between Mean Rate of Photon Absorption and productivity levels.

Summary: The study focused on isolating and identifying three indigenous microalgae species with high growth performance from Setiu wetlands, Terengganu, Malaysia, namely Chlorella vulgaris, Tetraselmis chuii, and Isochrysis galbana, over a 16-day culture period. These microalgae exhibited the highest optical density and specific growth rate, as well as fluorescence intensity for lipid, carotenoid, and chlorophyll a content. Salinity variations were found to significantly impact the growth and biochemical composition of these microalgae species.

Summary: Reciprocal metabolite exchanges between diatoms and bacteria can enhance the growth of both partners and therefore fundamentally influence aquatic ecosystem productivity. We studied the growth-promoting capabilities of 15 different bacterial isolates from the bacterial community associated with the marine diatom Actinocyclus sp. and found that co-culture with these isolates increased the growth of the diatom host, with different bacteria showing varying effects at different stages of the diatom's life cycle.

Summary: This study investigates the effect of light intensity and culture medium on the growth and nutritional composition of microalgae Nannochloropsis oculata and Porphyridium cruentum. It is found that higher light intensity and certain culture medium conditions lead to higher protein content and higher content of certain vitamins in N. oculata. On the other hand, P. cruentum shows higher carbohydrate content under lower light intensity.

Summary: Microalgae, such as diatoms, are emerging as production systems for recombinant proteins like monoclonal antibodies. Efficient analytical methodologies are required to characterize the N-glycosylation machinery of the host cell and the glycoprotein-based bio-pharmaceuticals produced by microalgae. This study found that the diatom Phaeodactylum tricornutum can synthesize human-like oligomannosides, making it an environmentally friendly and advantageous expression system for producing biopharmaceuticals.

Summary: Storing multiple energy forms from microalgae is not only facile but also lowers the cost of culturing the microalgae. Diatoms, among many microalgae, are responsible for converting stored lipids and biomass into hydrogen, and their silica frustules have immense applications in nanotechnology for hydrogen production and energy storage. This review discusses the scope and approaches to produce hydrogen from live diatoms and their biomass, highlighting their economic aspects and wide applications.

Summary: With declining fish stock in the world's oceans, there is a growing need to improve and make aquaculture more sustainable. Diatoms, a type of unicellular protist, are considered the most suitable microalgae for producing live feeds in mariculture due to their size, digestibility and nutritional content. They can also synthesize various bioactive compounds that promote the health and survival of aquatic species, while remediating the eutrophic nutrients in aquaculture wastewater. This review highlights the importance of diatoms in aquaculture and their potential for bioremediation and biomass valorization, aiming to establish a circular bioeconomy.

Summary: Pharmaceuticals are an important group of emerging pollutants with the potential to harm wildlife and humans. They have been detected in various types of water bodies and the organisms living in them. Traditional wastewater treatment is unable to completely remove pharmaceuticals, leading to their discharge into aquatic ecosystems. However, little is known about the effects of pharmaceuticals on phytoplankton, especially diatoms, which are crucial organisms in aquatic systems. This review aims to present a synthesis of research on pharmaceutical exposure to diatoms, exploring their ecotoxicity, bioremediation potential, and use as bio-indicators for water quality assessment.

Summary: The gut microbiota in fish, which includes bacteria, archaea, yeast, and fungus, plays a crucial role in various functions such as food digestion, nutrient absorption, and immune response. The interaction between the microbiota and pathogens can either protect the host or lead to dysbiosis and diseases. Understanding these interactions is important for preventing pathogen establishment in fish hosts.
