Research Status and Trends of Microalgae in Soil Improvement Based on Bibliometric Analysis
In recent years, frequent soil degradation has severely constrained food security. Microalgae, as a novel soil conditioner, has demonstrated significant potential in enhancing degraded soil quality and sustainable agricultural productivity, becoming a current research hotspot. To investigate the research status and trends of microalgae-mediated soil improvement, 164 Chinese and 688 English papers were separately retrieved from China National Knowledge Infrastructure (CNKI) and Web of Science core collection (WOS). Bibliometric approaches combined with CiteSpace software were used for systematic analysis of domestic and international publications. Results indicate that annual publication volume has risen overall since 2001. China and India hold prominent research positions, accounting for 32.85% of total WOS publications; among these, the Chinese Academy of Sciences leads globally in both publication volume and influence. Domestically, research efforts are primarily concentrated in the Northwest and North China regions. Chlorella vulgaris is the most studied core microalgae species in both Chinese and English literature, with Chinese studies emphasizing practical agricultural applications while English literature covers both fundamental research and macro-level ecological-economic topics. Chronologically, early CNKI literature (2001-2014) examined microalgae-soil interactions, while the mid-period (2015-2019) emphasized algal fertilizer development, soil conditioning, and pollution remediation. Recent research (2020-present) focuses on precision improvement of specific soils and key production indicators. WOS literature evolved from ecological remediation (2010-2017) to system optimization research integrating circular economy concepts (2018-present). Looking ahead, efforts should focus on four key areas: integrating the deepening of micro-level mechanisms with the expansion of macro-level applications; shifting from single-purpose soil improvement to “multifunctional synergy”; achieving breakthroughs in key technologies that reduce costs and enhance efficiency; and advancing research through cross-disciplinary integration. This research provides a theoretical foundation for degraded soil remediation and green transformation of agriculture, while offering technical support for the global synergistic application of microalgae.

Soil is the basis of agricultural production, and the quality of soil directly affects crop quality and yield. Microalgae can carry out photosynthesis, carbon and nitrogen fixation, and produce large amounts of valuable biomass coupled with wastewater treatment. Also, microalgae can produce plant hormones and other high-value products, which can promote plant growth, improve soil fertility, soil ecological health, and control crop diseases. This research reviews the characteristics of microalgae in improving soil health, discusses the situation of microalgae in controlling soil pollutants, elaborates on the technical application of microalgae in alleviating soil problems, and proposes potential applications of microalgae in ecological environment. Also, resource utilization of multifunctional microalgae is discussed, to provide a theoretical basis for the application of microalgae in soil improvement.

Biofuel-bioenergy production has generated intensive interest due to increased concern regarding limited petroleum-based fuel supplies and their contribution to atmospheric CO2 levels. Biofuel research is not just a matter of finding the right type of biomass and converting it to fuel, but it must also be economically sustainable on large-scale. Several aspects of cyanobacteria and microalgae such as oxygenic photosynthesis, high per-acre productivity, non-food based feedstock, growth on non-productive and non-arable land, utilization of wide variety of water sources (fresh, brackish, seawater and wastewater) and production of valuable co-products along with biofuels have combined to capture the interest of researchers and entrepreneurs. Currently, worldwide biofuels mainly in focus include biohydrogen, bioethanol, biodiesel and biogas. This review focuses on cultivation and harvesting of cyanobacteria and microalgae, possible biofuels and co-products, challenges for cyanobacterial and microalgal biofuels and the approaches of genetic engineering and modifications to increase biofuel production.Copyright © 2011 Elsevier Ltd.

Investigations were done on two former open-cast lignite mining sites under reclamation, an artificial sand dune in Welzow Süd, and a forest plantation in Schlabendorf Süd (Brandenburg, Germany). The aim was to associate the topsoil hydrological characteristics of green algae dominated as well as moss and soil lichen dominated biological soil crusts during crustal succession with their water retention and the repellency index on sandy soils under temperate climate and different reliefs.

Due to the constant growth of the human population and anthropological activity, it has become necessary to use sustainable and affordable technologies that satisfy the current and future demand for agricultural products. Since the nutrients available to plants in the soil are limited and the need to increase the yields of the crops is desirable, the use of chemical (inorganic or NPK) fertilizers has been widespread over the last decades, causing a nutrient shortage due to their misuse and exploitation, and because of the uncontrolled use of these products, there has been a latent environmental and health problem globally. For this reason, green biotechnology based on the use of microalgae biomass is proposed as a sustainable alternative for development and use as soil improvers for crop cultivation and phytoremediation. This review explores the long-term risks of using chemical fertilizers for both human health (cancer and hypoxia) and the environment (eutrophication and erosion), as well as the potential of microalgae biomass to substitute current fertilizer using different treatments on the biomass and their application methods for the implementation on the soil; additionally, the biomass can be a source of carbon mitigation and wastewater treatment in agro-industrial processes.

Se is one of the essential nutrients for human health and animal growth; it participates in various physiological functions, such as antioxidant and immune response and metabolism. Se deficiency is related in the animal industry to poor production performance and the appearance of health problems in humans. Therefore, interest has arisen in producing fortified foods, nutritional supplements, and animal feed products enriched with Se. A sustainable strategy for bio-based products enriched with Se is microalgae. These are characterized by the ability to bioaccumulate inorganic Se and metabolize it into organic Se for product formulations of industrial interest. Although there are some reports on Se bioaccumulation, further exploration is needed to understand the effects of Se bioaccumulation in microalgae. Therefore, this article presents a systematic review of the genes or groups of genes that trigger biological responses associated with the metabolization of Se in microalgae. A total of 54,541 genes related to Se metabolization distributed in 160 different classes were found. Similarly, trends were identified through bibliometric networks on strains of greatest interest, bioproducts, and scientific production.
