Wicherhamomyces anomalus biofilm supported on wood husk for chromium wastewater treatment

Toxic heavy metals are harmful pollutants increasingly discharged in the environment by natural and anthropogenic means. Due to its widespread use in industrial processes, chromium presents a significant impact on the surface waters and ecosystem services. Because

Apple cider vinegar can help clear bacteria and yeast infections; a natural cure

The effect of apple cider vinegar on white blood cell clearance of microbes.

Antibiotic resistance poses a major health issue worldwide. There has never been a greater need for new anti-microbials which are natural, active on multiple organisms and ideally beneficial to the patient. Bacteria such as E-Coli, Staphylococcus aureus

Using glowing yeast to keep food safe

Dioxins and dioxin-like chemicals (DLCs) are a problematic group of pollutants that come from both natural and man-made origins. They do not easily break down on their own, which means that once they are present in an

Evolution and adaptive value of yeast epigenetic memory of previous growth in galactose

Cellular adaptation to environmental changes often entails transcriptional responses that promote survival and proliferation. In certain cases, “memory” of previous experiences promotes a much faster transcriptional response upon second exposure to the same stimuli, leading to faster

Studying potential endocrine disrupting chemicals: comparison of yeast and human cell-based in vitro assays

The production of chemicals for agricultural and industrial use, cosmetics or food additives is steadily increasing. To protect the environment and human health against the potential risks arising from these man-made chemicals, the authorities introduced several programs

Yarrowia lipolytica: how a yeast becomes a workhorse for biotechnology

Yarrowia lipolytica is a yeast species belonging to the Ascomycota fungi phylum (like the well-known baker’s and brewer’s yeasts, both from Saccharomyces cerevisiae species). This innocuous yeast can be found in a large range of ecosystems (soils,

Oral microorganisms: how do they communicate?

Many oral diseases are related to the interaction between microorganisms in the oral cavity.  These microbial interactions are necessarily associated with the development of dental plaque and can lead to oral diseases including dental caries and perhaps

Over-expression of TRX2 reduces p53-mediated cell death in yeast

The p53 gene is a human tumor suppressor which is involved in cell cycle regulation. It has an efficient ability to inhibit cell proliferation, by both blocking cell cycle progression and promoting apoptotic cell death in order

How do microorganisms survive in extreme conditions?

You may have taught how extreme regions like glaciers, mountains, and deep oceans are habitats for many organisms including bacteria, archaea, algae, and yeasts as well as glaciers ice worms, plants and animals. These organisms survive in

Osmoregulation in phytopathogenic fungi

Osmosis is a phenomenon in which water moves always from higher to lower chemical potential, commonly towards the area with higher solute concentration. Living cells are semi-closed systems with membranes permeable for water but not for many

A better understanding of cell division by combining mathematical modeling and experimentation

The cell division cycle is the process by which a growing cell replicates its genome and partitions the two copies of each chromosome to two daughter cells at division. It is of utmost importance to the perpetuation

Cold denaturation

Most proteins can be thought like beady chains which form compact well-ordered coils whose surface protects the greasy-like interior from the contact with water molecules. We are studying what are the forces which keep the coil compact.

Yeasts have a toolbox for modification of hyaluronan

Hyaluronan, or hyaluronic acid, is a high molecular weight polysaccharide, which is abundant in the extracellular matrix of soft connective tissues, and is an important constituent of humans’ body. Molecules of hyaluronan play many biological roles. Enzymes,

Yeasts make your life sweet!

Recently was found that the low-calorie sweetener Erythritol might be produced from waste by special species of yeast, Yarrowia lipolytica. Erythritol is natural, tastes almost exactly like table sugar, but it does not cause obesity. Erythritol belongs
