Antagonistic potential of Wickerhamomyces anomalus against phytopathogens causi...
Amorim-Rodrigues, Mariana; Cássio, Fernanda; Lucas, CândidaOlive Anthracnose (OA) and Chestnut Ink Disease (CID), caused by eukaryotic organisms such as fungi and oomycetes, pose significant challenges to agricultural production, causing severe yield losses and reduced quality of harvested products. Currently, chemical pesticides are widely used to control these pathogens. However, this approach can be expensive and ineffective, and may have detrimental environmental a...
The extracellular matrix of yeasts: A key payer in the microbial biology change...
Lucas, Cândida; Silva, CoralieMicrobes are traditionally regarded as planktonic organisms, individual cells that live independently from each other. Although this is true, microbes in nature mostly live within large multi-species communities forming complex ecosystems. In these communities, microbial cells are held together and organised spatially by an extracellular matrix (ECM). Unlike the ECM from the tissues of higher eukaryotes, microb...
Yeasts as new powerful bio-tools for sustainable agriculture: Biocontrol of pla...
Lucas, Cândida; Cássio, FernandaCrop diseases caused by fungi or oomycetes are responsible for significant losses in food production worldwide, and are increasingly recognized as a global threat to food security. This crisis derives from concurring factors, which include agricultural practices, global trade and climate change, all of which synergistically impact plants’ fitness, critical to the maintenance of function and services of agro-eco...
Vinasse waste from sugarcane-based bioethanol production plants kills Monilioph...
Ferraz, P.; Amorim-Rodrigues, M.; Cássio, Fernanda; Lucas, CândidaBioethanol production based on sugarcane juice fermentation yields vinasse, a dark, dense liquid waste high in potassium. In Brazil, one of the world’s biggest bioethanol producer, vinasse is used for fertirrigation of the sugar-cane fields, replacing mineral soil amendments. Nevertheless, the production largely exceeds this application, prompting exacerbated usage, unduly long-term storage and even illegal dum...
Moniliophthora perniciosa, the Causal Agent of Cacao Witches’ Broom Disease Is ...
Ferraz, Pedro; Brandão, Rogelio Lopes; Cássio, Fernanda; Lucas, CândidaCacao plantations from South America have been afflicted with the severe fungal disease known as Witches’ Broom Disease (WBD), caused by the basidiomycete Moniliophthora perniciosa. Yeasts are increasingly recognized as good fungal biocides, although their application is still mostly restricted to the postharvest control of plant and fruit decay. Their possible utilization in the field, in a preharvest phase, i...
Physical, genetic and functional interactions between the eisosome protein Pil1...
Tulha, Joana; Amorim-Rodrigues, Mariana; Esquembre, Lidia Alejo; Rauch, Sebastien; Tamás, Markus J.; Lucas, CândidaThe Saccharomyces cerevisiae MBOAT O-acyltransferase Gup1 is involved in many processes, including cell wall and membrane composition and integrity, and acetic acid-induced cell death. Gup1 was previously shown to interact physically with the mitochondrial membrane VDAC (Voltage-Dependent Anion Channel) protein Por1 and the ammonium transceptor Mep2. By co-immunoprecipitation, the eisosome core component Pil1 w...
Draft genome sequence of Wickerhamomyces anomalus LBCM1105, isolated from cacha...
Cunha, Aureliano C.; Santos, Renato A Corrêa Dos; Riaño-Pachon, Diego M.; Squina, Fábio M.; Oliveira, Juliana V. C.; Goldman, Gustavo H.Wickerhamomyces anomalus LBCM1105 is a yeast isolated from cachaça distillery fermentation vats, notable for exceptional glycerol consumption ability. We report its draft genome with 20.5x in-depth coverage and around 90% extension and completeness. It harbors the sequences of proteins involved in glycerol transport and metabolism.
High-affinity transport, cyanide-resistant respiration, and ethanol production ...
da Cunha, Aureliano Claret; Gomes, Lorena Soares; Godoy-Santos, Fernanda; Faria-Oliveira, Fábio; Teixeira, Janaína AparecidaWickerhamomyces anomalus strain LBCM1105 was originally isolated from the wort of cachaça (the Brazilian fermented sugarcane juice-derived Brazilian spirit) and has been shown to grow exceptionally well at high amounts of glycerol. This paramount residue from the biodiesel industry is a promising cheap carbon source for yeast biotechnology. The assessment of the physiological traits underlying the W. anomalus g...
Protective effect of ions against cell death induced by acid stress in Saccharo...
Sant’Ana, Gilzeane dos Santos; Paes, Lisvane da Silva; Paiva, Argentino F. Vieira; Fietto, Luciano Gomes; Totola, Antônio HelvécioSaccharomyces boulardii is a probiotic used to prevent or treat antibiotic-induced gastrointestinal disorders and acute enteritis. For probiotics to be effective they must first be able to survive the harsh gastrointestinal environment. In this work, we show that S. boulardii displayed the greatest tolerance to simulated gastric environments compared with several Saccharomyces cerevisiae strains tested. Under t...
Potential of yeasts as biocontrol agents of the phytopathogen causing cacao Wit...
Ferraz, Pedro; Cássio, Fernanda; Lucas, CândidaPlant diseases caused by fungal pathogens are responsible for major crop losses worldwide, with a significant socio-economic impact on the life of millions of people who depend on agriculture-exclusive economy. This is the case of the Witches' Broom Disease (WBD) affecting cacao plant and fruit in South and Central America. The severity and extent of this disease is prospected to impact the growing global choco...
