“…They show for example interesting self-assembling properties and phasebehavior (Worakitkanchanakul et al, 2009;Fukuoka et al, 2012), cell-differentiation activity (Isoda et al, 1997) and interaction with proteins (Konishi et al, 2007). They have also been reported to be valuable ingredients for hair and skin care products (Morita et al, 2010;Yamamoto et al, 2012), for agro-chemicals (Fukuoka et al, 2015), and they could be used as surface-modifiers in bioplastics (Fukuoka et al, 2018).…”

“…Our previous studies showed that solutions containing MEL can disperse across a variety of surfaces, including hydrophobic plastics and plant leaves 18 . Additionally, MEL treatments can enhance the wettability of hydrophobic surfaces and have been shown to facilitate the spread of microbial cells on plant surfaces.…”

INTRODUCTION Biosurfactants BSs are functional amphiphilic compounds produced by a variety of microorganisms. Compared to chemically synthesized surfactants, BSs are more eco-friendly, biocompatible, and multifunctional. Glycolipid-type BSs are the most promising BSs for many industrial processes because of their availability from renewable resources, such as vegetable oils and sugars, and their versatile interfacial and biochemical properties 1, 2. Sophorolipids SL are a class of glycolipid-type BSs that can be easily mass produced 3. Starmerella bombicola is a high-yield producer of SL over 400 g/L 4 6. Naturally synthesized SL are mixtures of lactonic and acidic forms with a content ratio that depends on the specific species of the producers. SL are surface-active and exhibit low toxicity, high biodegradability, and antimicrobial properties. Many are currently used as additives in cleaning products and cosmetics 7, 8. Mannosylerythritol lipids MEL are also produced by fungal strains of the genus Pseudozyma or Ustilago 9, 10. MEL also boast excellent interfacial properties, specific self-assembly, and a variety of biological activities 1 .

“…It is well known that P . antarctica has ability to secrete mannosylerythritol lipids that can decrease the contact angle of water droplets and the spreading of microbial cells onto plant surface 35 . It might be possible that these extra components in the PaE active/inactivated crude enzyme solutions also contributed to the enhancement of B .…”

The phylloplane yeast Pseudozyma antarctica secretes an esterase, named PaE, and xylanase when cultivated with xylose. We previously observed that the lipophilic layer of Micro-Tom tomato leaves became thinner after the culture filtrate treatment. The leaves developed reduced water-holding ability and became wilted. In this study, the purified enzymes were spotted on Micro-Tom leaves. PaE, but not xylanase, thinned the lipophilic layer of leaves and decreased leaf resistance to the phytopathogenic fungus Botrytis cinerea. Disease severity increased significantly in detached leaves and potted plants treated with the culture filtrate and B. cinerea spores compared with those treated with inactivated enzyme and B. cinerea alone. Spore germination ratios, numbers of penetrating fungal hyphae in the leaves, and fungal DNA contents also increased significantly on the detached leaves. Japanese knotweed (Fallopia japonica), a serious invasive alien weed in Europe and North America, also became susceptible to infection by the rust pathogen Puccinia polygoni-amphibii var. tovariae following the culture filtrate treatment. The culture filtrate treatment increased disease development in plants induced by both phytopathogenic fungi. Our results suggest that P. antarctica culture filtrate could be used as an adjuvant for sustainable biological weed control using phytopathogenic fungi.
