 © Johanna Rotko  ///  BIO ART LAB 2025
Visual artist Johanna Rotko works with living materials, mainly different yeasts. In the future she wants to broaden her palette with microbes. As in yeast images i.e. yeastograms, various microbes: yeasts, bacteria, molds, fungi, mycelium, and other unidentified species, grow. She photographs the diverse changes in yeast images on a regular basis during their existence. Carbon recyclers i.e. molds, play a major role as yeast images age.
Art, that uses alive elements is based on the manipulation of the living matter this is also the case with yeast images. After the exposure Rotko influences the images as little as she can and the creatures that grow on the images are in the environment or on the plate itself. The artist lets them be because nature does not need our care, even on a larger scale. She moves from the manipulator to the observer role and the yeast images return to the cycle of nature through biowaste disposal. She started bokashi-composting with the microbial images in the summer of 2022. The plates are going to return to the soil, she is eager to find out how plants like these nutrients. Now citrus trees are growing on her kitchen windowsill.
