Zusammenfassung: | This study demonstrates the efficacy of employing
Rhizopus oryzae
fungus inoculum as a potential solution to improve soil erodibility in coastal environments. A set of unconfined compression tests is conducted on Miami Beach sand treated with a
R. oryzae
inoculum. Our findings suggest that the
R. oryzae
fungus inoculum effectively improves the stability of sand by acting as a natural binding agent. This finding aligns with previous studies that utilized different Rhizopus species, such as
Rhizopus oligosporus
, to improve sand properties. However, a notable difference is observed; the
R. oryzae
-treated sand exhibits remarkable durability, maintaining significant strength over an extended period without water or dietary supply. The durability is likely attributable to the morphological characteristics of
R. oryzae
that extensively branches its mycelial network. This paper shares the new discovery to the bio-geotechnics research community, potentially allowing for the customization of soil improvement process by choosing between the fast-acting
R. oligosporus
and the longer-lasting
R. oryzae
