The Laetiporus polyketide synthase LpaA produces a series of antifungal polyenes
TLDR
The identification of an eight-domain mono-modular highly reducing polyketide synthase as sole enzyme necessary for laetiporic acid biosynthesis is described, which underscores the diversity-oriented character of basidiomycete natural product biosynthesis.
Injury-induced biosynthesis of methyl-branched polyene pigments in a white-rotting basidiomycete.
TLDR
A stereaceous basidiomycete was investigated with regard to its capacity to produce yellow pigments after physical injury of the mycelium and demonstrated a polyketide backbone and that the introduction of the sole methyl branch is most likely S-adenosyl-l-methionine-dependent.
Lipid and fatty acid profile of the edible fungus Laetiporus sulphurous. Antifungal and antibacterial properties
TLDR
Results indicated that hexane extracts possessed better antifungal and slightly better antibacterial activity compared to chloroform extracts though both were less active than the commercial antimicrobial agents.
Comparative Studies on the Induction of Trichoderma harzianum Mutanase by α-(1→3)-Glucan-Rich Fruiting Bodies and Mycelia of Laetiporus sulphureus
TLDR
It was shown that the cell wall preparation (CWP) obtained from the fruiting body or vegetative mycelium of polypore fungus Laetiporus sulphureus is rich in α-(1→3)-glucan and can be successfully used for mutanase induction in Trichoderma harzianum.
Production of extracellular polysaccharides by submerged mycelial culture of Laetiporus sulphureus var. miniatus and their insulinotropic properties
TLDR
The EPS were proved to be glucose-rich polysaccharides and were able to increase proliferation and insulin secretary function of rat insulinoma RINm5F cells, in a dose-dependent manner, and strikingly reduced the streptozotocin-induced apoptosis in Rinm5f cells indicating the mode of the cytoprotective role of EPS on RIN m5F Cells.
Production of natural colorants by liquid fermentation with Chlorociboria aeruginascens and Laetiporus sulphureus and prospective applications
TLDR
This study was able to scale up the production of xylindein by Chlorociboria aeruginascens from 3 to 70 L bioreactor cultivations and described for the first time the use of this pigment in silk dyeing, which results in a brilliant hue that cannot be produced by other natural pigments.
Induced Chemical Defense of a Mushroom by a Double-Bond-Shifting Polyene Synthase.
TLDR
This study represents the first characterization of a reducing polyketide synthase from a mushroom and shows that injury-induced de novo synthesis of polyketides is a fungal response strategy.
Extraction, purification and physicochemical properties of a novel lectin from Laetiporus sulphureus mushroom
Multi-omics analysis provides insights into lignocellulosic biomass degradation by Laetiporus sulphureus ATCC 52600
TLDR
The singularity of L. sulphureus ATCC 52600 is shown compared to other Polyporales brown rots, regarding the presence of cellobiohydrolase and peroxidase class II, and the oxidative–hydrolytic metabolism involved in lignocellulose deconstruction is reinforced.
In vitro cultivation of Laetiporus sulphureus and evaluation of its antimicrobial properties.
TLDR
The results shown that the types of culture media for biomass production of L. sulphureus and their aqueous and alcoholic extracts tested against these pathogens have different effects on inhibitory activity.

Carotenoids and Fatty Acids in Red Yeasts Sporobolomyces roseus and Rhodotorula glutinis
TLDR
Rhodotorula glutinis and Sporobolomyces roseus, grown under different aeration regimes, showed differential responses in their carotenoid content, indicating a biosynthetic switch at the γ-carotene branch point of carotanoid biosynthesis.
Singlet Oxygen and Peroxyl Radicals Regulate Carotenoid Biosynthesis in Phaffia rhodozyma(*)
TLDR
It is shown that the active oxygen species singlet oxygen (1O2) and peroxyl radicals differently affect carotenoid composition and biosynthesis in the yeast Phaffia rhodozyma, providing the first report of induction of astaxanthin biosynthesis by 1O2, probable feedback control by astXanthin, and the oxidative degradation of astxanthin to novel pigments in P. r Rhodozyma.
Intraspecific comparisons of Laetiporus sulphureus isolates from broadleaf and coniferous trees in Europe
TLDR
There is evidence that more than one species or ecotype is represented within the current definition of L. sulphureus, circumscription of additional taxa, and separations within this taxon remain unclear.

Molecular characterization of nucleotide sequences encoding the extracellular glycoprotein elicitor from Phytophthora megasperma
TLDR
cDNA sequences encoding the 42 kDa glycoprotein elicitor from the oomycete, Phytophthora megasperma, that induces the defense response in parsley have been cloned and sequenced and a region of 47 amino acids located in the C-terminal third of the protein was sufficient to confer elicitor activity.

TLDR
The variety of environmental and cultural stimulants studied during the last few decades which enhance volumetric production and cellular accumulation of commercially important carotenoids from microalgae, fungi and bacteria are described.
Incompatibility groups among North American populations of Laetiporus sulphureus sensu lato.
TLDR
Pairings of tester SSIs from each of the LIGs withSSIs from an addi- tional 42 collections of Laetiporus confirm the mutual exclusiveness of theLIGs and the association of the the Ligs with the LRGs as well as other characteristics and are worthy of recognition at the species level.
