Ruminal bioremediation of the high energy melting explosive (HMX) by sheep microorganisms

Ruminal bioremediation of the high energy melting explosive (HMX) by sheep microorganisms.

The ability of ruminal microorganisms to degrade octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (high melting explosive, HMX) as consortia from whole rumen fluid (WRF), and individually as 23 commercially available ruminal strains, was compared under anaerobic conditions. Compound degradation was monitored by high-performance liquid chromatography, followed by liquid chromatography-tandem mas...

Analysis of peptide metabolism by ruminal microorganisms.

Methods were developed for the determination of oligoalanine and other short-chain peptides and peptide analogs in ruminal fluid by using reverse-phase high-pressure liquid chromatography. Chromatographic analysis of the breakdown of (Ala)3 and (Ala)4 in ruminal fluid in vitro revealed that the predominant mechanism of hydrolysis was a dipeptidyl peptidase-like activity. Hydrolysis proceeded fr...

The effect of ajowan (Carum copticum L.) essential oils on eukaryotic ruminal microorganisms of Mehraban sheep

BACKGROUND AND OBJECTIVES Essential oils may improve the utilization of nutrients by ruminal microorganisms. The aim of this study was to assess the effect of different doses of ajowan essential oils (AEO) on growth and fibrolytic activity of anaerobic fungi, and generic distribution of ciliated protozoa (in vitro). MATERIAL AND METHODS Different doses of AEO (0, 150, 300, 450 and 600 ppm) we...
