The study of the intersection between biodiversity and biotechnology has revealed a rich source innovations. Fungi, with their vast range morphologies lifestyles, thrive in various habitats, including caves. With impressive metabolic characteristics, they play key role producing essential biotechnological compounds for economic sectors. This paper aims to consolidate evidence on potential fungi isolated from caves, highlighting urgency conserving exploring these ecosystems. For this purpose, we conducted comprehensive literature search using scientific databases (SciELO, Medline Complete, Medline/PubMed, Web Science, Scopus (Elsevier), Google Scholar). We adopted an interdisciplinary approach by collecting information 22 papers published 2013 2024. Based data, our survey broad potential, antimicrobial compounds, antioxidants, antitumor agents, enzymes, organic acids. emphasize that accurately identifying depositing fungal isolates reference collections are crucial reliable research effective industrial applications, driving bioactivity production substances inhibit pathogens.

Host-microbe interactions underlie the development and fitness of many macroorganisms, including bees. Whereas social bees benefit from vertically transmitted gut bacteria, current data suggests that solitary bees, which comprise vast majority species diversity within lack a highly specialized microbiome. Here, we examine composition abundance bacteria fungi throughout complete life cycle ground-nesting bee Anthophora bomboides standfordiana. In contrast to expectations, immature stages maintain distinct core microbiome consisting Actinobacterial genera (Streptomyces, Nocardiodes) fungus Moniliella spathulata. Dormant (diapausing) larval hosted most abundant distinctive fungi, attaining 33 52 times their initial copy number, respectively. We tested two adaptive hypotheses regarding microbial functions for diapausing First, using isolated found Streptomyces brood cells inhibited growth multiple pathogenic filamentous suggesting role in pathogen protection during overwintering, when face high pressure.

Abstract In this study, we successfully isolated two distinct yeasts from Moroccan extreme environments. These were subjected to molecular characterization by analyzing their Internal Transcribed spacer (ITS) regions. Our research thoroughly characterizes plant growth-promoting abilities and drought salt stress tolerance. a greenhouse assay, examined the impact of selected on Medicago sativa’s growth. Four treatments employed: (i) control without inoculation (NI), (ii) with L1, (iii) L2, (iv) mixture L1 + L2. Toubkal Mountain shared 99.83% sequence similarity Rhodotorula mucilaginosa. Meanwhile, thriving in arid Merzouga desert, displayed similar identity Naganishia albida (99.84%). Yeast strains tolerant NaCl (2 M) 60% PEG (polyethylene glycol P6000) case drought. Both could solubilize phsphorus, L2 additionally demonstrating potassium solubilization. addition, both produce indole acetic acid (up 135 µl ml−1), have siderophore ability, aminocyclopropane-1-carboxylic deaminase. Isolates consortium showed that single or combined strain M. sativa improved growth, development, nutrient assimilation. findings pave way for harnessing yeast-based solutions agricultural practices, contributing enhanced crop productivity environmental sustainability.

Yeast biodiversity in mangrove ecosystems is crucial for their health and ecological functions. However, traditional methods often fail to detect yeast species that are difficult culture or slow growing, leaving a significant portion of this undetected. This study explores the use environmental DNA (eDNA) as an alternative method identifying ecosystems, addressing data gaps left by conventional methods. Data collected from various relevant literature sources, including scientific journals, books, research reports. The review reveals eDNA analysis can improve conservation management providing robust assessments. Future should focus on understanding persistence, implications, improving bioinformatics better interpretation. In-depth long-term studies recommended temporal spatial dynamics communities ecosystems. Further validation conditions needed ensure reliability.
