“…[17], Damayanti et al 2018 also showed the diversity of Streptomyces sp. BCy which was isolated from Cymodocearotundata seagrass using two different media [18], Sarkar and Suthindhiran (2022) also suggested the diversity of marine actinobacteria from different marine ecosystems and found 30 types of actinobacteria from various types of seaweed such as Cymodaceae sp., Enhalus sp., Halophila sp., Halodule sp., Syringodium sp., and Thalassia sp. [19].…”

Cellulase enzymes have been widely used in many industrial activities, such as the production of biofuels, biofertilizers, and bio-decomposers. The usage of cellulase enzymes on an industrial scale usually involves a relatively high temperature. Microorganisms in marine ecosystems are widely known to have the ability to produce cellulase enzymes in various environmental ranges. However, exploring marine cellulolytic bacteria at low temperatures still lacks information. This study aims to determine the cellulolytic activity of bacteria associated with seagrass ecosystems at low temperatures. Cellulolytic activity test used selected bacteria isolates from the seagrass ecosystem (actinobacteria: AA10b, AA11a, AA30a, AB22b; heterotrophic bacterial: HB1.1, HB2.1, HT1.2, HT2.2). The cellulolytic index values were obtained from the clear zone test on CMC 1% medium with congo red staining (actinobacteria) and iodine (heterotrophic bacteria) in different temperature treatments (4°C, 17°C, 20°C, and 40°C). The results showed that all isolates had various cellulolytic index values at different temperatures. There was no bacterial cellulolytic activity at 4°C. However some isolates showed activities at 17°C and increased as the temperature was higher. The highest production of cellulolytic activity occurred at 40°C for both actinobacteria and heterotrophic bacteria isolates. The actinobacteria isolate AA11a had the highest cellulolytic index of 7.00 at 40°C. This study indicates that at low temperatures, associative bacteria from the seagrass ecosystem have considerable cellulolytic activity for further research applications in various industries.

“…With that, the vegetative cover of seagrasses provides a significant substratum for the rich diversity of organisms, including actinobacteria which forms an integral part of the seagrass ecosystem [9,[67][68][69]. Actinobacteria are among the pioneer colonizers of seagrasses [70] and their diversity varies between seagrass species [52,53]. The seagrass-derived actinomycetes are capable of producing antimicrobial agents (Table 1).…”

The search for novel therapeutic agents to combat the crisis of antimicrobial resistance has spanned from terrestrial to unique, marine environments. Currently, most of the drugs available for usage are derived from microbial metabolites, especially those belonging to the bacterial group, actinobacteria. Actinobacteria are hotspot organisms that exist in all habitats with a myriad of unique biosynthetic metabolites. Seagrasses appear to be a key ecosystem within the coastal environment worth bioprospecting for novel natural products. Unfortunately, literature about the bioactive potential of their associated prokaryotes, including actinobacteria remains limited. In this context, this review focused on actinobacteria with antibiotic-producing capabilities derived from different parts of seagrass plants (i.e. roots, rhizomes, and leaves). To date, there were no purified molecules derived from seagrass-associated actinobacteria that were subjected to structure elucidation. From the underpinning of numerous biological profiles such as antibacterial, antifungal, and algicidal activities of seagrass-derived actinobacteria reported in this review during the period from 2012–2020, it provides a continual growth of knowledge accruing overtime, providing a foundation for future research.
