Microbial-Induced Calcite Precipitation in Unsaturated Soil
Unsaturated soil is a form of natural soil whose pores are filled by air and water. Different from saturated soil, the microstructure of unsaturated soil consists of three phases, namely, the solid phase (soil particle), vapor phase, and liquid phase. Due to the matric suction of soil pores, the hydraulic and mechanical behaviors of unsaturated soils present a significant dependence on the moisture condition, which usually results in a series of unpredictable risks, including foundation settlement, landslide, and dam collapse. Microbial-induced calcite precipitation (MICP) is a novel and environmentally friendly technology that can improve the water stability of unsaturated soft or expansive soils.

Microbial Fuel Cells
The intensive energy requirement of conventional wastewater treatment for aeration demands an alternative technological option that requires less energy for its operation. Due to its cost-effectiveness, biological processes such as activated sludge have been widely used for wastewater treatment. However, this technique depends on the ability of bacterial population to maintain acceptable effluent quality. If the treatment is interfered with, the bacterial population respond to the varying influents. When this occurs, exceeding effluent limits lead to environmental damage and costly fines. Consequently, treatment facilities have to be overhauled, resulting in a loss of time and financial resources.

Microbial Enzyme Applied to Plastic Depolymerization
The accumulation of synthetic plastic waste in the environment has become a global concern. Microbial enzymes (purified or as whole-cell biocatalysts) represent emerging biotechnological tools for waste circularity; they can depolymerize materials into reusable building blocks, but their contribution must be considered within the context of present waste management practices.

Microbial Desalination Cell Performance Indicators and Limiting Factors
Microbial desalination cells (MDCs) are promising bioelectrochemical systems for desalination using the bacteria-generated electricity from the biodegradation of organic wastes contained in the wastewater. Instead of being a sustainable and eco-friendly desalination technology, the large-scale application of MDC was limited due to the high installation cost of the metal-catalyst-coated cathode electrode and the poor performance of the cathode in long-term operation due to catalyst fouling.

Microalgae-Based Biorefineries: Challenges and Future Trends
Microalgae-based biorefineries allow the simultaneous production of microalgae biomass enriched in a particular macromolecule and high-added and low-value products if a proper selection of the microalgae species and the cultivation conditions are adequate for the purpose.

Microalgae Cultivation
Microalgae is a renewable resource with potential value as a commodity and for combating climate change. Commercial cultivation can be done through open ponds or photobioreactors (PBRs), with open ponds being less expensive. PBRs offer potential better controls but are hindered by cost-related issues. Outdoor PBRs are a promising solution, but challenges related to relying on natural resources remain. Further research is needed to make PBRs commercially viable.

Microalgae Biomass and Biochemical Conversion
Among the available renewable resources, microalgae biomass, a third-generation feedstock, is promising for energy production due to its rich biochemical composition, metabolic elasticity, and ability to produce numerous bioenergy products, including biomethane, biohydrogen, and bioethanol.

Microalgae and Photolysis as New Energy Technologies
Because of the near-term risk of extreme weather events and other adverse consequences from climate change and, at least in the longer term, global fossil fuel depletion, there is worldwide interest in shifting to noncarbon energy sources, especially renewable energy (RE). Because of possible limitations on conventional renewable energy sources, researchers have looked for ways of overcoming these shortcomings by introducing radically new energy technologies. The largest RE source is bioenergy, while solar energy and wind energy are regarded as having by far the largest technical potential.

Micro-Nanotechnology Sensors for Biomedical and Environmental Challenges
Micro- and nanotechnology-enabled sensors have made remarkable advancements in the fields of biomedicine and the environment, enabling the sensitive and selective detection and quantification of diverse analytes. In biomedicine, these sensors have facilitated disease diagnosis, drug discovery, and point-of-care devices. In environmental monitoring, they have played a crucial role in assessing air, water, and soil quality, as well as ensured food safety.
