The Effects of Oral Polysaccharide Administration on Immune Responses, Antioxidant Activity and Resistance Against in the Common Carp, L.

The effects of the oral administration of polysaccharide (RGP-1) on the immunoregulatory properties, antioxidant activity, and resistance against in L. were investigated. The purified RGP-1 (250, 500, and 1,000 μg/mL) was co-cultured with the head kidney cells of the common carp.

sp. nov., an actinomycete isolated from a soil sample.

A novel actinomycete strain, designated CFH S0054, was isolated from a soil sample collected from Xiaokongshan in Tengchong, Yunnan Province, in south-west PR China. Phylogenetic analysis based on its 16S rRNA gene sequence indicated that strain CFH S0054 belonged to the genus . Based on the results of 16S rRNA gene sequence analysis, strain CFH S0054 was most closely related to IFM 0354 (98.

Iodobacter limnosediminis sp. nov., isolated from Arctic lake sediment.

A Gram-reaction-negative, motile, non-violet-pigmented, rod-shaped bacterial strain, designated E1(T), was isolated from Arctic lake sediment. Growth occurred at 4 °C-28 °C (optimum, 18 °C), at pH 4-11(optimum, 9-10) and in the presence of 0-1 % (w/v) NaCl. The taxonomic position of E1(T) was analysed using a polyphasic approach.
