A static batch culture system inoculated with human faeces was used to determine the influence of essential oil compounds (EOCs) on mixed faecal microbiota. Bacteria were quantified using quantitative PCR of 16S rRNA genes. Incubation for 24 h of dil

Effects of a specific preparation of essential oil compounds on rumen fermentation were determined using four mature sheep, each fitted with a permanent rumen cannula and receiving 110 mg per day of dietary essential oils compounds (EO; CRINA RUMINAN

The microbiota of the intestinal tract plays an important role in colonic health, mediating many effects of dietary components on colonic health and during enteric infections. In the context of the increasing incidence of antibiotic resistance in gut

It was suggested that poly(dA).poly(dT) rich sequences in yeast Saccharomyces cerevisiae act as elements of constitutive promoters by exclusion of nucleosomes (Struhl, K. (1985). Proc. Natl. Acad. Sci. USA 82, 8419-8423). We have mapped the chromatin

Small linear DNA molecules containing histone octamers (nucleosome cores) are transcribed by SP6 RNA polymerase with only slightly lower efficiency than naked DNA templates. The position of the histone octamer on the DNA remains unchanged even after

We have attacked H1-containing soluble chromatin by alpha-chymotrypsin under conditions where chromatin adopts different structures. Soluble rat liver chromatin fragments depleted of non-histone components were digested with alpha-chymotrypsin in NaC

We have studied in reconstitution experiments the conditions under which peptides derived from histones H1 and H5 are bound in chromatin and to what extent they are involved in the organization of chromatin fibers. The fragments of rat liver histone
