[Microecological distribution of toxin-producing bacteria in Fug rubripes in Bohai Sea and biological characteristics of B3B].

The study showed that toxin-producing bacteria were commonly existed in each part of Fugu rubripes body. 19 strains of high poisonous bacteria were isolated from its ovary, liver and other tissues, among which, strain B3B was identified as genus Bacillus based on its physiological and biochemical characteristics and 16SrDNA sequence, and could produce tetrodotoxin through mouse test, thinner chromatography, and mass spectrography.

[Research advances in plant growth-promoting rhizobacteria and its application prospects].

The study of plant growth-promoting rhizobacteria will provide possible methods to overcome the difficulties in controlling soil borne plant diseases. PGPR can colonize in rhizosphere at high population density, inhibit plant pathogens and deleterious microorganisms there, and promote crop growth and its yield. More importantly, some PGPR strains applied as biocontrol agents can make treated plant produce induced systemic resistance (ISR), and thus, increases plant overall health. In recent two decades, the researches of PGPR in abroad are very active, and many PGPR products have been applied successfully. In our contry, more attention should be paid to the study of the basic theory and application of GPPR and the industrialization of PGPR products.

[Bio-active substances derived from marine microorganisms].

Marine microorganisms, which are taxonomically diverse and genetically special, have powerful potential in producing novel bio-active substances. This article summarized research progress in this respect. The results showed that marine bacteria which are main marine microorganism flora can produce rich kinds of bio-active substances and that even though marine actinomycetes and marine fungi are not as many as marine bacteria in species and quantity, they should be paid no less attention about their bio-active substances. Besides, present research are limited to those marine microorganisms which are easily cultured. One of the future research trends will be focused on bio-active substances derived from non-culturable marine microorganisms.
