Sagrario Mochales

TL;DR: Phosphonomycin is a newly discovered antibiotic produced by streptomycetes that is effective, when administered by the oral route, to mice infected with Gram-positive or Gram-negative microorganisms.

TL;DR: A new beta-lactam antibiotic, named thienamycin, was discovered in culture broths of Streptomyces MA4297, and subsequently determined to be a hitherto unrecognized species, is designated StrePTomyces cattleya (NRRL 8057).

TL;DR: A number of actinomycetes isolated from soil were found to produce one or more members of a new family of antibiotics, the cephamycins, which are structurally related to cephalosporin C.

TL;DR: Two novel macrocyclic polyene lactone phosphate esters were discovered in fermentation broths of each of two strains of Bacillus subtilis and each showed a broad spectrum of activity against aerobic and anaerobic bacteria.

TL;DR: Hypoxylon, with at least 130 currently accepted species and varieties, is one of the largest genera of the Xylariaceae as discussed by the authors, and taxonomic aspects that define and delimit the genus have varied among the authors.
