Abstract:

Compost is generally used as an organic fertilizer or soil conditioner, and its effects on soil quality and plant growth have been thoroughly investigated. Recently we have reported that a compost fermented marine animals could impart physiological benefits to plants as well as animals. The biphasic functions of the compost are as follows: 1) Application of the compost to soil results in an increase of crop yield, and suppression of plant diseases caused by several plant pathogens. In addition, decreased nitrate and increased amino acids in plants are also observed. 2) Oral administration of the compost to flatfish reduces the number of dead flatfish in the nursery. When the compost extract has continuously been given to pigs in swine farms, the rate of stillbirth is decreased and the growth of piglets is promoted. In rodent models, the level of fecal immunoglobulin A, a gut mucosal barrier, raises following the compost exposure. Interestingly, oral administration of the compost extract reduces visceral fat in the mice mimic metabolic syndrome. Microbial analyses reveal that the compost contains Bacillus sp. expressed cyclic lipopeptides with antagonistic activity to plant fungal pathogens, and bacterial strains such as Bacillus sp. and Brevibacillus sp. to activate denitrification or nitrogen fixation. Furthermore, Bacillus sp. possible to modulate immune response and nutrient utilization in rodents have been isolated from the ceca of germ free mice fed the compost extract. Thus, further investigation on the functions of thermophilic isolates from the compost is necessary.
