Lactobacillus rhamnosus and Lactobacillus plantarum cell-free culture supernatants (CFSs) were highly effective in suppressing in vitro biofilm growth of Candida albicans and Candida tropicalis. L. acidophilus's effect on C. albicans and C. tropicalis was negligible; however, its impact on inhibiting C. parapsilosis biofilms was remarkably more potent. The inhibitory effect of L. rhamnosus CFS neutralized at pH 7 persisted, leading to the conclusion that exometabolites apart from lactic acid, generated by the Lactobacillus strain, could be responsible for this effect. Subsequently, we quantified the inhibitory potential of L. rhamnosus and L. plantarum cell-free supernatants regarding the filamentous transition of Candida albicans and Candida tropicalis strains. A diminished amount of Candida filaments was evident after co-incubation with CFSs under hyphae-inducing circumstances. Real-time quantitative PCR was employed to determine the expression levels of six biofilm-associated genes (ALS1, ALS3, BCR1, EFG1, TEC1, and UME6 in Candida albicans and their corresponding counterparts in Candida tropicalis) in biofilms that were co-incubated with CFS. The expression of genes ALS1, ALS3, EFG1, and TEC1 was downregulated in the C. albicans biofilm, in comparison to the untreated control sample. Within C. tropicalis biofilms, the expression levels of ALS3 and UME6 were reduced, while the expression of TEC1 increased. The combined action of L. rhamnosus and L. plantarum strains resulted in an inhibitory effect on the filamentation and biofilm formation of C. albicans and C. tropicalis, which is probably a consequence of metabolites released into the culture environment. Based on our findings, an alternative to antifungals emerges for the management of Candida biofilm.

The use of light-emitting diodes has seen a surge in recent decades, replacing incandescent and compact fluorescent lamps (CFLs), leading to a considerable increase in electrical equipment waste, predominantly in the form of fluorescent lamps and CFL light bulbs. Discarded CFL lights, and the materials they are composed of, are prime sources of rare earth elements (REEs), a cornerstone of most modern technological advancements. Pressure is mounting on us to find alternative sources of rare earth elements that are both sustainable and capable of fulfilling the rapidly growing need, due to the erratic availability of these elements. read more Bio-removal of waste containing rare earth elements (REEs) and their subsequent recycling may be a feasible strategy for achieving a sustainable balance of environmental and economic benefits. The current research project employs the extremophilic red alga, Galdieria sulphuraria, for the remediation of rare earth elements within hazardous industrial waste originating from compact fluorescent light bulbs, and assesses the physiological reaction of a synchronized Galdieria sulphuraria culture. Following treatment with a CFL acid extract, a noticeable influence was observed on the growth, photosynthetic pigments, quantum yield, and cell cycle progression of this alga. Utilizing a synchronous culture, rare earth elements (REEs) were gathered efficiently from a CFL acid extract. This efficiency was improved by the addition of two phytohormones, 6-Benzylaminopurine (a cytokinin) and 1-Naphthaleneacetic acid (an auxin).

Ingestive behavior shifts are crucial for animals adapting to environmental alterations. Although we understand that changes in animal diets result in modifications to the structure of gut microbiota, the precise relationship between fluctuations in nutrient intake or food items and the subsequent changes in the composition and function of the gut microbiota still needs clarification. To examine the influence of animal feeding strategies on nutrient absorption and consequent modification of gut microbiota composition and digestive processes, we chose a cohort of wild primates for our investigation. We determined the dietary habits and macronutrient intake of these subjects during four seasons, and high-throughput 16S rRNA and metagenomic sequencing were applied to instantaneous fecal samples. read more The seasonal shifts observed in gut microbiota are mainly due to the changes in macronutrient intake caused by seasonal differences in dietary habits. Microbial metabolic processes in the gut can help to compensate for inadequate macronutrient intake in the host. This study sheds light on the causes of seasonal changes in the microbial diversity of wild primates, contributing to a more profound understanding of this ecological process.

Researchers have documented two newly discovered Antrodia species, A. aridula and A. variispora, originating from the western regions of China. Using a six-gene dataset (ITS, nLSU, nSSU, mtSSU, TEF1, and RPB2), the phylogeny reveals that the samples from the two species form separate lineages within the Antrodia s.s. clade, exhibiting unique morphological features compared to the existing species of Antrodia. The annual, resupinate basidiocarps of Antrodia aridula are distinguished by angular to irregular pores, each measuring 2-3mm, and oblong ellipsoid to cylindrical basidiospores, 9-1242-53µm in size, which develop on gymnosperm wood in arid conditions. Picea wood serves as the substrate for Antrodia variispora, whose annual, resupinate basidiocarps display sinuous or dentate pores of 1 to 15 mm. Oblong ellipsoid, fusiform, pyriform, or cylindrical basidiospores, measuring 115 to 1645-55 micrometers, are characteristic of this species. This article examines the distinctions between the new species and morphologically comparable species.

Rich in plants, ferulic acid (FA) is a natural antibacterial agent, effectively neutralizing harmful microbes and boasting excellent antioxidant properties. Because of its short alkane chain and high polarity, FA faces an obstacle in penetrating the soluble lipid bilayer within the biofilm, which impedes its cellular entry for its inhibitory function, thus restraining its biological activity. read more The antibacterial activity of FA was enhanced by synthesizing four alkyl ferulic acid esters (FCs) with variable alkyl chain lengths, through the modification of fatty alcohols (including 1-propanol (C3), 1-hexanol (C6), nonanol (C9), and lauryl alcohol (C12)), catalyzed by Novozym 435. To evaluate the effect of FCs on P. aeruginosa, Minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) were determined, along with growth curves, alkaline phosphatase (AKP) activity, crystal violet assay, scanning electron microscopy (SEM), membrane potential analysis, propidium iodide (PI) staining, and cell leakage assessment. The antibacterial activity of FCs underwent an increase after esterification, and a significant rise and subsequent dip in activity was observed as the alkyl chain length within the FCs was extended. Hexyl ferulate (FC6) displayed the most effective antibacterial activity against both E. coli and P. aeruginosa, characterized by MIC values of 0.5 mg/ml for E. coli and 0.4 mg/ml for P. aeruginosa. Among the antibacterial agents tested, propyl ferulate (FC3) and FC6 demonstrated the superior ability to inhibit Staphylococcus aureus and Bacillus subtilis, achieving MICs of 0.4 mg/ml and 1.1 mg/ml, respectively. Furthermore, the study investigated the growth, AKP activity, bacterial biofilm formation, bacterial cell morphology, membrane potential, and cell content leakage of P. aeruginosa subjected to various FC treatments. The results indicated that FC treatments could compromise the structural integrity of the P. aeruginosa cell wall, exhibiting diverse impacts on the P. aeruginosa bacterial biofilm. Among the tested inhibitors, FC6 displayed the superior ability to prevent biofilm formation by P. aeruginosa, leaving the cell surfaces rough and wrinkled.
