Abstract

‘Everything is everywhere, but the environment selects’

– Lourens Baas Becking

This quote by Dutch botanist Lourens Baas Becking, when extended to microbiology, implies the activities of microorganisms are defined by the environment in which they find themselves, with biotic and abiotic factors alike impacting their activity, metabolism and viability. This is definitely true of Bdellovibrio bacteriovorus-and-like-organisms (BALOs), which are influenced directly by both their environment and the prey metabolic activities, stimuli that can have drastic impacts on the predatory activities of these strains. The goal of this chapter, therefore, is to delve deeper into, and gain a better understanding of, the correlation between predatory bacteria and their environment. Towards this end, we discuss here many of the factors and conditions (biotic and abiotic) that impact BALOs and their activities, including the osmolality, oxygen, serum albumin and indole. We hope through this discussion young scientists will gain a significant understanding of the current hurdles holding BALOs back from many real-world applications, such as in treatment of bacterial infections or within wastewater treatment systems, and encouragement to find solutions.
