Importance and role

Importance of genus to ecosystem

As the litter of mangroves contains a lot of cellulose and lignin, and fungi are one of the main decomposers in nature, a lot of researchers focused on the cellulose and lignin decomposing enzymes. Pointing et al. (1999) and Raghukumar et al. (1999) have found that most fungi can produce cellulose and ligninase in the process of decomposing mangrove leaves. Acuminatispora comprises a single species and as saprobes in the mangrove environment, it may be of some significance to conduce follow-up research on the compound product of its culture.


Industrial relevance and applications

There are presently no industrial applications of Acuminatispora. Acuminatispora is a marine-derived fungi and can be a valuable source of enzymes of industrial importance. Further studies are warranted for screening any natural bioactive compounds and enzymes derived from Acuminatispora.


Quarantine significance

There is currently no accurate information regarding pathogenicity status of Acuminatispora and no disease have been apparently detected from this genus.


Biochemical importance of the genus, chemical diversity or applications

Acuminatispora comprise only one species and is not well-known in other part of the world. More species of Acuminatispora need to be discovered to analyze their chemical diversity.


Diversity of the genus

Acuminatispora accommodates a single species as mentioned above. Acuminatispora seems to be an important component of phytoplankton and marine algae populations. Knowledge of Acuminatispora species diversity will increase with more intensive work in rather little-studied regions.
