Industrial Applications of Soil Microbes is a compilation of reviews on the industrial usage of soil microorganisms. Readers will be updated about recent applications of soil bacteria, fungi and viruses in sectors such as agriculture, biotechnology, environmental management. Volume 4 includes review on mycorrhizal fungi, endophytes and a range of microbial chemicals and processes beneficuall at industrial scale. The 19 chapters start with an overview of mycorrhizae as biofertilizers, their symbiosis with plants, and their applications in improving crop yield, stress management, and soil health. Case studies on Lycopersicon esculentum highlight practical benefits. Soil microbes, endophytes, and microbial proteases are discussed for their role in biocontrol, disease management, and crop improvement. The volume also explores eco-friendly nematicides, viruses in temperate fruit crops, mushrooms’ nutritional value, and metagenomics for bioinoculants. Overall, the volume emphasizes sustainable practices and future prospects involving microbes and microbe-assisted processes. Readership General readers, microbiology and biotechnology enthusiasts, science students and industrial trainees
