Aeromonas spp. are commonly found in spoilage of chilled meat. Aeromonas salmonicida NCM 29 and Aeromonas salmonicida NCM 57 have been discovered the spoilage heterogeneity in degrading myofibrillar protein. In this study， the two strains were tested to uncover the discrepancy of meat spoilage in collagen-rich chilled meat and extracted collagen. The results revealed that chicken claws， riched in collagen， inoculated with NCM 29 showed higher values of total viable counts (TVC)， total volatile basic nitrogen (TVB-N)， pH， adhered cells， TCA-soluble peptides， and protease activity compared to those inoculated with NCM 57. Furthermore， NCM 29 generated higher quantity of volatile organic compounds related to meat spoilage. The collagenase (hemagglutinin protease， Hap) secreted by NCM 29 has been identified as the key factor responsible for the observed discrepancies in spoilage， which gradually degraded collagen into peptides and hydroxyproline. The capacity of Hap to degrade type I collagen in vitro indicated that it has apparent proteolytic activity， which could reduce the average particle size and alter secondary structure of collagen. SDS-PAGE further confirmed the degradation of the β chain in collagen. These findings not only provide a theoretical basis for in-depth investigation of the meat spoilage mechanisms of Aeromonas spp.， but also encourage us to take measures to avoid the spoilage of related bacteria such as Aeromonas spp. during the preservation process.

Chromosome constitution was investigated in adult tetraploid Pacific oyster produced by blocking the first polar body oftriploid eggs which were fertilized with haploid sperms. A high incidence of aneuploid and heteroploid mosaics were found amongthe offspring. Of 20 individuals identified, only 9 （45%） were eutetraploid which contained 40 chromosomes; 2 （10%） were ane-uploid （hypotetraploid）, which contained 39 and 38 chromosomes, respectively; and 9 （45%） were heteroploid mosaics. One mosaicwas consisted of cells containing 40 and 39 chromosomes, respectiovely （1：1 in cell number）, while the other 8 were consisted ofcells containing chromosomes varying between tetraploid and triploid. It was also interesting to note that 3 mosaics even containedsome diploid cells with 20 chromosomes. A certain number of cells of 2 tetraploids and 8 mosaics spread with 32-37 well-scatteredand some clumped chromosomes at metaphase. The percentage of aneuploid cells with chromosomes varying between triploid andtetraploid correlated significantly with that of heteroploid mosaics cells with clumping chromosomes （P〈0.05）. Our findings sug-gested that reversion existed in both tetraploid and triploid oyster and chromosome clumping may underline the chromosome elimi-nation in tetraploid oyster. It seems that the reversing cells, at least some of them, continuously eliminate their chromosomes until themost stable diploid state is established.

Artificially induced tetraploid Pacific oyster, Crassostrea gigas Thunberg, produces more aneuploid gametes than normal diploid one, although they showed a comparable fecundity to diploidy. The meiotic chromosome configuration of 3 tetraploid and 1 tetraploid/triploid mosaic males were analyzed through direct chromosome observation. A majority of metaphase I spermatocytes contained both bivalents and quadrivalents. The chromosome configuration of these males was characterized by preferential formation of bivalents to quadrivalents. Bivalents appeared in all spermatocytes and consisted of 86% of all chromosome aggregates. In comparison, quadrivalents occurred in 91% spermatocytes and consisted of only 12.6% of all chromosome aggregates. The mean bivalent frequency per spermatocyte varied between 14.4 and 17.2; while that of quadrivalents varied between 2.2 and 2.7. Most quadrivalents were tandemly chained(58%) or circled(39%). The total number of chromosome aggregates per spermatocyte ranged from 13 to 20 with an average of 17.6; while 18(16 bivalents and 2 quadrivalents) was the most frequent. Univalents and trivalents appeared in very low frequency. Aneuploid(hypotetraploid) spermatocytes were observed in a low frequency. The chromosome configuration of in the mosaic individual was similar to that of tetraploid individuals. The percentage of triploid spermatocytes(2%) of the mosaic individual was significantly lower(χ2 =30, P < 0.01) than that of triploid cells(46%) in its somatic tissue.
