TL;DR: In this article, a metagenomic analysis of the bacterial community resident in the hindgut paunch of a wood-feeding Nasutitermes species (which do not contain cellulose-fermenting protozoa) was performed to show the presence of a large, diverse set of bacterial genes for cellulose and xylan hydrolysis.

TL;DR: Genomic libraries constructed from microbial DNA isolated from insect intestinal tracts from the orders Isoptera and Lepidoptera were screened for genes that encode proteins with xylanase activity and several novel xylan enzyme enzymes with unusual primary sequences and novel domains of unknown function were discovered.

TL;DR: The findings suggest that the ethnopharmacological approach is useful in guiding the detection of antifungal plants in Latin America mainly for infections in which the pathological expression is obvious and, therefore, the cure can be clearly observed.

TL;DR: In this paper, the core structures of spiroketal naphthodecalins are assembled by Barton's base mediated Ullmann binaphthyl ether coupling, Dakin reactions and hypervalent iodine spirocyclization.

TL;DR: The SRB cytotoxicity assay was used to screen plant extracts, in a collaborative multinational OAS project involving Argentina, Bolivia, Colombia, Costa Rica, Guatemala, Nicaragua and Panama, against breast, lung, and central nervous system human cancer cell lines, finding Piper barbatum, Senna occidentalis, and Blepharocalyx salicifolius.
