Bugün öğrendim ki: Trichoderma reesei adlı bir mantarın, yaşlanan ve çökmekte olan altyapıları düzeltmeye yardımcı olabileceğini söyledi. Bu mantar betonla karıştırıldığında, ilk çatlak görünene kadar başlangıçta uykuda kalır. Uyuyan mantar sporları, çatlakları iyileştirmek için filizlenecek, büyüyecek ve kalsiyum karbonatı çökeltecektir.

America's crumbling infrastructure has been a topic of ongoing discussion in political debates and campaign rallies. The problem of aging bridges and increasingly dangerous roads is one that has been well documented and there seems to be a consensus from both democrats and republicans that something must be done.
