Published: March 2024

We present a novel optical nanomotion-based rapid antibiotic and antifungal susceptibility test. The technique consisted of studying the effects of antibiotics or antifungals on the nanometric scale displacements of bacteria or yeasts to assess their sensitivity or resistance to drugs. The technique relies on a traditional optical microscope, a video camera, and custom-made image analysis software. It provides reliable results in a time frame of 2-4 h and can be applied to motile, non-motile, fast, and slowly growing microorganisms. Due to its extreme simplicity and low cost, the technique can be easily implemented in laboratories and medical centers in developing countries.

Drone larvae (DL) has many biological activities thanks to the bioactive components it contains, but there are very few studies on its antimicrobial activity. The aim of this research was to determine the antifungal activity of DL (raw and lyophilised) water and ethanol extracts against fluconazole (FLU) sensitive and resistant yeast strains. The 87 fungal strains obtained from clinical samples were identified by phenotypic and molecular methods, and broth microdilution test was used for antifungal activity.

One strategy for adding unique characteristics and flavors to improve coffee quality is the selection of starter microorganisms. Here, we aimed to evaluate the effect of LNFCA11 and B10 as starter cultures on the quality of four different wet-fermented coffee varieties. Microbiological, molecular, and chemical analyses were carried out to identify yeast, bacteria, volatile compounds, carbohydrates and bioactive compounds in coffee.
