The most recent trend in research on probiotic bacteria aims at the exploitation of bioactive bacterial compounds that are responsible for health-promoting effects and suitable for medical applications. Therefore, the main purpose of this study was to ascertain if the immunomodulatory effects of L. paracasei strains on dendritic cells (DCs) were caused by bacterial metabolites released in the c...

1. When a guinea pig with well developed peritoneal tuberculosis is injected intraperitoneally with about 20 cc. of a heavy suspension of a virulent tubercle bacillus (Culture H37) death occurs within 24 hours or the animal becomes extremely toxic. Such a peritoneal tuberculosis develops in about 1 month after 1 cc. of. a very heavy suspension of Culture H37 has been introduced into the abdomin...

In present investigation, for the development of Fusarium tolerant varieties in carnation, highly susceptible cultivars viz. Tempo and Raggio de Sole were used. Calli caraation irradiated to different doses gamma irradiation. And Callus surviving at highest dose rays was mass multiplied on callus multiplication medium (MS +10 μNAA + 10 μM kin). Irridiated calli after multiplication, treated wit...

Two new antibiotics SF2315A and B have been isolated from culture filtrate of an actinomycete strain, Excellospora viridilutea SF2315. They are weakly active against Gram-positive bacteria and inhibited reverse transcriptase of avian myeloblastosis virus. Empirical molecular formula of antibiotics SF2315A and B were determined to be C19H16O5 and C19H20O6, respectively.

Six strains of Actinomadura pelletieri were shown to produce a novel macrolide antibiotic, designated MM 46115. MM 46115 was active against parainfluenza virus 1 and 2 and Gram-positive bacteria. Methods are described for the production of MM 46115 by strain IP 729.63, and for the isolation of the compound from a butanol extract of the culture filtrate.

A new antibiotic capuramycin was isolated from the culture filtrate of Streptomyces griseus 446-S3 by adsorption and partition column chromatography. Based on its chemical structure being an uracil nucleoside with a caprolactam substituent, this substance was named as capuramycin. This paper describes the taxonomy of a producing organism, fermentation, isolation, characterization and biological...

Oligostatins C, D and E, three new antibiotics were found in the culture filtrate of Streptomyces myxogenes nov. sp. SF-1130. Their spectral and chemical properties suggested that oligostatins were basic oligosaccharide antibiotics. They exhibited not only antibacterial activity but also strong amylase inhibitory activity.

Vaccination of mice with Mycobacterium bovis culture filtrate proteins (CFP), prepared in a variety of adjuvants (aluminum hydroxide, Quil-A, and dimethyldioctyldecyl ammonium bromide [DDA]), provided significant protection against an aerosol challenge of virulent M. bovis. Additionally, vaccination with CFP in DDA or Quil-A did not sensitize mice to M. bovis purified protein derivative.
