recognizing new items and their biosynthetic pathways is still under examination. Cryptic metabolic pathways have been explored using molecular techniques or culture-dependent approaches. In recent years, researchers¿ primary interest is to identify the specific conditions or agents that wake the cryptic antibiotics. Several bioinformatics and synthetic biology tools were developed to explore new antibiotics from actinobacteria. The book comprises 14 chapters with different aspects of application and utilization of actinomycetes from the microbiology; systems biology, pharmacology of natural products, bioinformatics, actinomycete and its diversity, CRISPR, artificial Intelligence, synthetic biology, metabolic engineering, expressional studies, and biosynthetic gene clusters. The book delivers useful information on actinomyces to researchers, novices in genome designing, specialists, clinicians, policymakers, and professionals.
