The Indigenous Probiotic PH3-05 Enhances the Growth, Digestive Physiology, and Gut Microbiota of the Tropical Gar () Larvae.

Probiotics in aquaculture hold promise for enhancing fish health and growth. Due to their increased specificity and affinity for their host, indigenous probiotics may offer isolated and potentially amplified benefits. This study investigated the effects of PH3-05, previously isolated from adults of tropical gar (), on the growth, survival, digestive enzyme activity, intestinal morphology, expression of barrier and immune genes, and intestinal microbiota composition in the larvae of tropical gar.

Antifungal Activity of ZnO Nanoparticles Synthesized from Extract for Construction Applications.

Fungal growth on construction materials in tropical climates can degrade aesthetics and manifestations on modern and historical sick buildings, affecting the health of their inhabitants. This study synthesized ZnO nanoparticles with enhanced antifungal properties using a precipitation method. Different concentrations (25%, 50%, and 100%) of aqueous extract were used with Zn(NO)·6HO as the precursor to evaluate their spectroscopic, morphological, textural, and antifungal properties.

Fungal community dynamics on limestone at the Chichén Itzá archaeological site in Mexico driven by protective treatments.

Microorganisms naturally colonize rock-based materials in outdoor environments, thereby contributing to their degradation. Fungi, especially in tropical environments with abundant water and favorable temperatures, play a significant role in biodegradation. However, many aspects of the microorganism-stone interaction, including fungal colonization dynamics and the impact of treatment applications, remain unclear.
