Abstract: Microorganisms were initially recognized with their deteriorative effects in the field of construction materials, similar to their first recognitions in most of the other fields. Nevertheless, over the past two decades, scientists have discovered how to benefit from microorganisms to improve the durability and sustainability of cementitious composites. Exploiting biomineralization became one of the most popular efforts in the field and led to development of bio-based self-healing concrete and bio-based surface protection methods. As developed concepts move towards the market, concerns and challenges such as application oriented performance optimization, cost-benefit performance and public acceptance appeared. Now, it is necessary to identify potential solutions for the current concerns and redefine our research paths accordingly. Here, the approaches such as replacing axenic cultures with non- axenic cultures, integrating the developed concepts into bio-based economy and exploring the added benefits of microorganisms for cementitious composites are discussed. Engineering of microbial cultures and combination of various benefits are the main bases of the discussion. Examples such as self-protected bacterial cultures and microbial induced corrosion inhibition of reinforcement bars are covered. Overall, the discussions are expected to be inspirational for researchers at all academic levels and thus enhance the dynamism and variety in the relevant field.
