“…Antimicrobial metabolites serve as potential alternatives that can hinder resistance to drugs for instance, extracts of endophytic fungi isolated from leaves, roots and barks of S. alba can restrict the growth of Staphylococcus aureus, Escherichia coli and Candida albicans (Chatterjee and Abraham 2020). Like the host plants, endophytic and rhizosphere microorganisms yield bioactive compounds or secondary metabolites as a result of coevolution (Rhamawati 2021); thus, mangroves can be a rich reservoir of potential bioactive substances.…”

Abstract. Dechavez R, Calub ML, Genobata DR, Balacuit R, Jose R, Tabugo SR. 2022. Identification of culture-dependent microbes from mangroves reveals dominance of Bacillus including medically important species based on DNA signature. Biodiversitas 23: 5342-5350. Mangroves are among the most crucial plant hosts in the marine environment because of their notable role in the ecosystem and their benefits. Identification of plant-associated and culture-dependent microbes is key to having a rich reservoir of bioactive substances. DNA barcoding was done based on 16S rRNA gene and ITS region. In this study, seven (7) mangrove species were identified as hosts. Results show that most bacterial isolates from plant leaves were gram-positive bacteria belonging to phylum: Firmicutes and genus Bacillus. Phylogenetic inference reveals a diverse non-monophyletic group with medically and economically necessary species. Among the host plants, Sonneratia alba harbored the most species of bacteria and fungi. These include two medically important strains of B. cereus and B. thuringiensis and host-specific bacteria like B. altitudinis in S. alba, B. velezensis in Rhizophora apiculata, B. clausii in Avicennia marina and B. firmus in A. marina were revealed. Meanwhile, some bacteria like B. subtilis and B. megaterium were found in three host species and B. cereus was the most abundant being recorded in four host plants. Diverse strains of fungi, Aspergillus sp., A. nomiae, A. tubingensis and A. niger were also present. This study served as baseline data for future research on diversity and host ecology for possible drug discovery.

“…Antibacterial chemicals are produced by a novel bacterium found in the endophytic and rhizospheric regions of the medicinal plant Acalypha indica Linn. Rhizosphere bacterial strain RU112B and RU315B were the most effective at preventing K. pneumoniae from growing (Rahmawati, 2021).…”

Organic farmers use nitrogen-fixing cover crops, herbicides, and biological fertilizers derived chiefly from animal and plant wastes. Curcumin levels are higher in this turmeric variety than in other types with differing pharmacological effects. Growing concerns about the safety of chemical fertilizers have heightened the need to identify locally adapted microbial strains that can be employed as a growth-promoting inoculum. Although research on the microbial diversity of the soil in Kandhamal and Koraput, India, was published, there is still a lack of information about the microbial community of the turmeric that is indigenous to these regions. This research compares and contrasts organically grown turmeric's growth-promoting and antibacterial activities with normally developed turmeric. This is a preliminary study that focuses on the microbiota communities of the study region. In vitro results showed that these properties have been shown to positively affect the development and nutritional content of studied turmeric plants; hence, they are regarded as key plant growth promoters. Using conventional and organic soil, both Kandhamal and Koraput rhizome sample was planted. The aqueous and methanolic rhizome extracts from both soil conditions were extracted. The Agar well diffusion method examined the rhizome extract's antibacterial activity. Bacteria were isolated and characterized from the rhizosphere and conducted various biochemical experiments. When tested against nine human pathogenic microorganisms, rhizomes harvested with vermicompost showed significantly increased antibacterial activity. The rhizospheric bacteria isolated from the organic soil region also help promote plant growth and development and provide adequate nutrients for growth and development. In every single experiment, the organically produced rhizome yielded superior results. The present study concludes that organic turmeric showed better and more effective results in increasing nutrient content, antibacterial activity and yield. Potential field applications necessitate more study into these rhizobacteria's molecular and functional characterization. Future improvements to biocontrol methods may come from studies examining the viability of deploying integrative, long-term bio-formulations in the field. The present research can potentially be used to investigate antibiotic synthesis by microbial communities in turmeric soil.
