This chapter intends to consider Pseudomonas versatility as regards the beneficial uses of Pseudomonas for production of primary metabolites including enzymes. This chapter will consider the use of Pseudomonas for production of secondary metabolites from various pathways which are equally useful in the industries and in medicine. Pseudomonas pigments and its usefulness in bioelectricity, medicine, etc. will equally be considered in this chapter. The authors are to integrate knowledge in versatility of Pseudomonas for use as agents of microbial production of biosurfactants for environmental cleanup, restoration, and remediation.
