“Mine-Derived Metal-Resistant Bacteria as Bionanofactories for Nanoparticle Synthesis: Mechanisms and Biomedical Potential”

𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁:
Deciphering various mechanisms of metal resistance in bacteria has been in progress over the past decades. It is currently being applied and explored in various fields, including nanoparticle (NP) biosynthesis. The link between bacterial resistance to metal(loid) ions and their ability to synthesize NPs has been reported by various researchers independently. Thus, this review presents the role of various metal resistance mechanisms in bacterial-mediated NP synthesis, emphasizing the promising potential of metal-resistant mine-derived bacteria as biological factories for synthesizing NPs. Several mechanisms of metal resistance that contribute to the formation of NPs include the production of exopolysaccharides (EPS), reactions catalyzed by proteins and enzymes, and reduction reactions involving thiol-containing molecules. The electrostatic attractive forces of the functional groups in the capsule, cell wall, and cell membrane with the metal ions are responsible for metal ion adsorption and NP formation. Furthermore, enzymes like c-cytochromes, different reductases like arsenate, mercuric, and nitrate reductases, as well as several thiol-containing biomolecules like metallothioneins (MTs) and glutathione (GSH) also play vital roles in the sequestration, reduction, and precipitation of toxic metal(loid) ions into NPs. Mining sites, being heavily metal-contaminated environments, are undoubtedly rich reservoirs of metal resistance as revealed by metagenomics studies. It confirms the presence of diverse metal-resistant bacterial strains capable of synthesizing NPs with a wide range of applications, particularly in the biomedical field. Risk-benefit analysis and growth condition management in large-scale production still impede biosynthesized NPs towards clinical and industrial translation. Hence, future research should focus on understanding the exact mechanism used by mine-derived metal-resistant bacteria in synthesizing NPs, standardizing formulations appropriate for human use, and optimizing the reaction for large-scale production.

𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁:
This study investigated the distribution of Ficus species and the composition and species-specific preferences of their associated frugivore communities in Mt. Banahaw de Tayabas, Quezon, Philippines. Specifically, the research aimed to construct a distribution map of Ficus species across an elevation gradient, determine the frugivore species interacting with these trees, and evaluate their visitation patterns in terms of frequency and time of interaction. A continuous line belt transect covering elevations from 500–1500 masl was established to document Ficus individuals using GPS-based mapping analyzed in QGIS. Five fruiting Ficus species were selected for frugivore monitoring using Browning camera traps deployed for 30 days, generating 3,600 total sampling hours. Recorded frugivore interactions were identified and analyzed, and species-specific association were assessed using crosstabulation and Chi-square tests of independence. Results revealed eight Ficus species distributed along the elevational gradient, with higher concentrations recorded in lowland and transitional forest zones. Camera trapping documented seven frugivorous vertebrate species, including Pteropodidae (Bats), Paradoxurus philippinensis, Corvus philippinus, Agamidae, Rattus everetti [Günther, 1879], Centropus bengalensis, Eudynamys scolopaceus, showing varying visitation frequencies across Ficus species. A statistically significant relationship was found between the variables based on the Pearson Chi-Square test (χ²(24) = 73.386, p < 0.001), indicating non-random associations. Supported by a significant linear-by-linear relationship (χ² = 8.832, p = 0.003) and confirmed by likelihood ratio test (χ² = 37.389, p = 0.040), which indicated significant value between frugivore visitation and specific Ficus species, reflecting differences in fruiting traits, accessibility, and tree structure. The study concludes that Ficus species are heterogeneously distributed along elevation and that frugivores exhibit distinct species-specific associations, underscoring the critical role of Ficus in sustaining vertebrate communities. These findings provide the first baseline distribution map of Ficus in Mt. Banahaw de Tayabas and highlight priority species and habitats essential for conservation. The results can guide protected area management, inform reforestation programs prioritizing keystone Ficus species, and support long-term biodiversity monitoring in the Mounts Banahaw–San Cristobal Protected Landscape.

𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁:
Macrofungal species in the mangrove ecosystem in the Philippines were diverse yet unexplored. Mangrove ecosystem is one of the favorable environments for macrofungi to grow and proliferate. The general objective of this study was to assess the mangrove forest in Sitio Waga Barangay Kanlurang Malicboy, Pagbilao, Quezon, Philippines by determining the diversity of mangrove macrofungi in the area. A total of 12 species of mangrove macrofungi from 8 families were found within the established 9 plots; Oxyporus populinus was the most abundant species recorded in the area. The study site has diverse species with a value of 0.83 using Simpson’s Index, and 2.06 using Shannon-Wiener Index. Species richness and species evenness were calculated to be 2.11 and 0.83, respectively, using Margalef’s formula and Pielou’s evenness index. Diversity on the three zonations of mangrove forests, such as landward, middleward, and seaward, were also assessed. The landward zone has the most individuals and the highest species richness of the three zonations.

𝗔𝗯𝘀𝘁𝗿𝗮𝗰𝘁:
Macapuno, the very soft endosperm of a coconut, is a commercially important crop. It is rare and high-value because the endosperm enclosing normal embryos impedes germination, effectively making the seeds sterile. Embryo - Culture of Macapuno (ECM) is the most efficient method of germinating normal embryos in vitro enclosed by the jelly-like solid endosperm of macapuno. In this study, two ECM protocols were compared to assess which produce viable plantlets that could be field-planted and produced high-yielding coconut seedlings. In Protocol 1, the explants received 7% sucrose in liquid media for 2 months, 5 months in solid media, and then back to liquid media until they are transplanted in soil medium or removed after 12 months of not developing. In Protocol 2, explants were germinated in liquid medium in the first month, solid media for growing explants with shoot and root primordia in the second month, and solid again for the remainder of the third and fourth months. In the fifth month, plantlets were supplied with 8% sucrose, while the remaining plants were grown in liquid media containing 8% sucrose. Results showed that Protocol 1 produced 11.33% plantlets in vitro, 2.67% were transplanted to soil media, and there was no survival during acclimatization stage while Protocol 2 have 25% plantlets in vitro, 16% were transplanted to soil media and there were 2.5% existing plantlets in vitro and 2.5% plantlets in acclimatization stage. Solid medium substantially aids in the induction of shoots and roots in the early stages of explants. Increasing sucrose levels from 7 to 8% when the stem of explants transforms into leaflets and soaking of seedlings to Indole-3-butyric acid (IBA) solution also benefits plant development. Efforts are still needed to adjust the protocols and adapt the explants for optimal germination, shooting, and rooting to improve the yields of coconut seedlings.
