Aspergillus parasiticus R-716의 生育, 脂質 및 Aflatoxin 生産에 미치는 마늘(Allium sativum L.)엑기스의 影響

다국어 초록 (Multilingual Abstract)

The possible effects of garlic (Aliium sativurn L.) extract on growth and aflatoxin production by Aspergillus parasiticus R- 716 were investigated. Various solvent extracts of garlic strongly inhibited growth and sporulation by Aspergillus parasiticus R-716, and effective solvents used for extraction of garlic were chloroform, benzene, and water-chloroform. The growth and aflatoxin production decreased with the increase in extract concentration, and extract equivalent 1.5g of raw garlic weight in 25ml SLS medium completely inhibited, and at a level of 1.25g garlic, total aflatoxin was reduced 64% (472μg/25ml) of that produced in the control (1, 352μg/25 ml). During cultivation inhibitory rate of growth was reduced from 89.1% to 40% and aflatoxin B₂, G₁ production increased with the laps of time. Especially garlic extract appeared to have a stimulatory effect on lipid accumulation on the contrary aflatoxin production.
