1. Effect of immunocastration on sex glands of male Mangulica (Swallow-bellied Mangalitsa) pigs
ABSTRACT The objective of this research was to study the effect of immunocastration on the morphometric characteristics of sex glands in male Swallow-bellied Mangalitsa pigs. The study included 24 animals (13 entire and 11 immunocastrated males). The research focused on the following traits: age at slaughter (days), live weight at slaughter (kg), growth rate

4. Similarity between the association factor of ribosomal subunits and the protein Stm1p from Saccharomyces cerevisiae
A ribosome association factor (AF) was isolated from the yeast Sacchharomyces cerevisiae. Partial amino acid sequence of AF was determined from its fragment of 25 kDa isolated by treating AF with 2-(2-nitrophenylsulfenyl)-3-methyl-3'-Bromoindolenine (BNPS-skatole). This sequence has a 86% identity to the product of the single-copy S. cerevisiae STM1 gene tha

5. Isolation and characteristics of a skatole-producing Lactobacillus sp. from the bovine rumen.
A bacterium that is capable of decarboxylating indoleacetic acid to skatole (3-methylindole) has been isolated from an L-tryptophan enrichment of bovine rumen fluid. The bacterium is a gram-positive, nonmotile, nonsporeforming rod. It is an obligate anaerobe, and strains predominatly produce D-(-)-lactic acid, with smaller amounts of L-(+)-lactic acid and ac

6. Dissimilation of Tryptophan and Related Indolic Compounds by Ruminal Microorganisms In Vitro1
Intraruminal doses of L-tryptophan cause acute pulmonary edema and emphysema in cattle. The D and L isomers of tryptophan and 22 related indolic compounds were incubated with ruminal microorganisms in vitro. Incubation of L-[U-benzene ring-14C]tryptophan with ruminal microorganisms for 24 h resulted in 39% of the added radioactivity being incorporated into s

7. Production of Skatole and para-Cresol by a Rumen Lactobacillus sp. †
The objective of this study was to examine the substrate specificity of several ruminal strains of a Lactobacillus sp. which previously was shown to produce skatole (3-methylindole) by the decarboxylation of indoleacetic acid. A total of 13 compounds were tested for decarboxylase activity. The Lactobacillus strains produced p-cresol (4-methylphenol) by the d

9. 3-Methylindole (skatole) and indole production by mixed populations of pig fecal bacteria.
Pig fecal slurries converted added L-tryptophan either to indole without detectable intermediates or to 3-methylindole (skatole) via indole-3-acetate. The initial rate of production of 3-methylindole was greatest at pH 6.5 and less at pH 5.0 and 8.0; the initial rates of indole production were similar at pH 6.5 and 8.0. More than 80% of the tryptophan added

10. Semisynthesis of sperm whale myoglobin by fragment condensation.
Reconstruction of the sperm whale myoglobin structure was accomplished by a series of aqueous condensations of suitably protected synthetic myoglobin fragments to a large fragment prepared from the native protein. Reaction of N alpha,N epsilon 19-acetimidomyoglobin with 3-bromo-2-(2-nitrophenylsulfenyl)skatole (BNPS-skatole) yielded the fragment correspondin

11. Comparison of three reagents for detecting indole production by anaerobic bacteria in microtest systems.
Three reagents for detecting indole, Kovac, Ehrlich, and p-dimethylaminocinnamaldehyde (DMCA), were evaluated with commercial microtest systems for characterizing and identifying anaerobic bacteria. The DMCA reagent, the most sensitive of the three reagents, gave a positive reaction with 445 of 449 strains of various indole-producing anaerobic bacteria. Ther

12. Nutritional requirements of Methanomicrobium mobile.
A defined medium was developed for Methanomicrobium mobile BP. M. mobile required acetate for growth; the optimal concentration was 30 mM. Other requirements and their optimal concentrations included isobutyrate (0.65 mM), isovalerate (0.73 mM), and 2-methylbutyrate (1.5 mM). The appropriate branched-chain amino acids did not substitute for these branched-ch
