Evaluation of antibacterial activity of extracts of five species of wood‐colonizing fungi

Abstract

Screening new organisms for antibacterial activity and searching for new antibacterial drugs is important due to the constant generation of new antibiotic-resistant strains of pathogenic bacteria. An E. coli broth microdilution test was used to evaluate the results of the Vibrio fischeri bioluminescence test in five of the most antibacterially active species of wood-colonizing fungi. Serpula lacrymans was found to be a potential source of thermostable antibiotic(s) and the Vibrio fischeri bioluminescence test was confirmed to be a useful method for screening for antibacterial activity.

Complex Biochemical Analysis of Fruiting Bodies from Newly Isolated Polish Flammulina velutipes Strains

“…In the beginning, mushrooms were valued for their flavor in preparation of dishes; nowadays, they are rather regarded as a source of nutraceuticals. Recent analyses have proved that mushrooms are important in our diet due to the high protein and low fat content (Barros et al, 2008); moreover, a number of papers have evidenced their value as antimicrobial, antioxidant, and anticancer compounds (Janes et al, 2006;Moradali et al, 2007;Karaman et al, 2010;Lemieszek and Rzeski, 2012). The results of our experiments support the findings that F. velutipes fruiting bodies may be a source of nutraceuticals in human diet.…”

Bacteria in decomposing wood and their interactions with wood-decay fungi

“…There is much in vitro evidence for antagonism amongst saproxylic micro-organisms, both of fungi against bacteria (Janes et al 2006;Popova et al 2009) and of bacteria against fungi (Murray and Woodward 2003;de Boer et al 2007;Caldeira et al 2008;Boaisha 2012). This is not necessarily evidence for antagonism in situ, given that the effect can depend on the culture medium (Murray and Woodward 2003;Boaisha 2012).…”

Role of ascomycete and basidiomycete fungi in meeting established and emerging sustainability opportunities: a review

“…This species is frequently employed since most are white-rot fungi with antibacterial properties. Brown-rot fungi such as Gloeophyllum trabeum and Serpula lacrymans [ 129 ], which contain nearly the same active chemical as white-rot fungus, can prevent the growth of dangerous microorganisms in the water.…”
