酵母可舉出屬酵母菌屬、接合酵母菌屬等之酵母,其中宜使用釀酒酵母(S. cervisiae)、魯氏接合酵母(Z. rouxii)、甜菜酵母(S. exiguus)等。乳酸菌可舉出例如屬片球菌(Pediococcus)屬、明串珠菌(Leuconostoc)屬、乳桿菌(Lactobacillus)屬、乳球菌(Lactococcus)屬等之乳酸菌,其中宜使用乳酸片球菌(P. acidilacti)、短乳酸菌(L. brevis)、腸膜明串珠菌(L. mesenteroides)、植物乳桿菌(L. plantarum)、乳酸乳球菌(L. lactis)、酒乳桿菌(L. sakei)、戊糖片球菌(P. pentosaceus)、乾酪乳桿菌(L. casei)、羅伊氏乳桿菌(L. reuteri)及彎曲乳桿菌(L. curvatus)等,可使用此等的1種或2種以上。麴菌可例示米麴菌(Aspergillus oryzae)、黑麴菌(Aspergillus niger)、白麴菌(Aspergillus kawachii)等,可使用此等的1種或2種以上。此等酵母、乳酸菌、麴菌可使用市售品、自委託機構等取得者等。Examples of yeast include yeasts belonging to the genus Saccharomyces and the genus Zygosaccharomyces. Among them, brewing yeast (S. cervisiae), Zygosaccharomyces rouxii, beet yeast (S. exiguus), etc. are preferably used. Examples of lactic acid bacteria include lactic acid bacteria belonging to the genus Pediococcus, the genus Leuconostoc, the genus Lactobacillus, and the genus Lactococcus. Among them, P. acidilacti, L. brevis, L. mesenteroides, L. plantarum, L. lactis, L. sakei, P. pentosaceus, L. casei, L. reuteri, and L. curvatus are preferably used. One or more of these may be used. Examples of koji molds include Aspergillus oryzae, Aspergillus niger, and Aspergillus kawachii, and one or more of these may be used. These yeasts, lactic acid bacteria, and koji molds may be commercially available or obtained from a consignment agency.
供予發酵之豆類/穀類、果實等植物可直接使用,或者可視需求進行粉碎、乾燥等前處理。又,亦可視需求添加水而予以稀釋。The beans/grains, fruits and other plants to be fermented can be used directly, or can be pre-treated by crushing, drying and the like as needed. In addition, water can be added to dilute it as needed.
上述(a)~(g)之發酵物可藉由對作為原料之植物接種乳酸菌、酵母或麴菌並進行培養而得。培養只要藉由常用方法來進行即可;例如只要對1種或2種以上之植物的混合物添加約0.001~1質量%的乳酸菌、酵母或麴菌,並以20~50℃進行發酵處理約70~140小時即可。The fermented products of (a) to (g) above can be obtained by inoculating lactic acid bacteria, yeast or koji into plants as raw materials and culturing them. The culturing can be carried out by common methods; for example, about 0.001 to 1% by mass of lactic acid bacteria, yeast or koji is added to a mixture of one or more plants and fermented at 20 to 50°C for about 70 to 140 hours.
亦可將如此所得之(a)~(g)之發酵物混合而直接作為有效成分,惟較佳視需求進一步以20~40℃培養約200~300小時。甚而,較佳使此混合物進行後發酵(熟成)。就後發酵,可視需求使酢酸菌作用,例如,只要添加酢酸發酵物即可;該酢酸發酵物係使上述酵母作用於上述(a)~(g)所包含之植物中的1種或2種以上後,使醋酸桿菌(A.aceti)等醋酸菌與其作用而得。後發酵只要以25~35℃進行70小時~約1年左右即可。經過後發酵之熟成過程,可改善呈味性或製劑性,並可增大抗氧化活性。The fermented products (a) to (g) thus obtained can also be mixed and used directly as an effective ingredient, but it is better to further culture at 20 to 40°C for about 200 to 300 hours as needed. It is even better to subject the mixture to post-fermentation (ripening). For post-fermentation, acetic acid bacteria can be allowed to act as needed. For example, acetic acid fermented products can be added; the acetic acid fermented products are obtained by allowing the above-mentioned yeast to act on one or more of the plants included in the above-mentioned (a) to (g), and then allowing acetic acid bacteria such as Acetobacter (A.aceti) to act on them. Post-fermentation can be carried out at 25 to 35°C for 70 hours to about 1 year. After the aging process of post-fermentation, the taste or preparation properties can be improved, and the antioxidant activity can be increased.
作為用於製造上述植物發酵物之較佳方法的實例,可舉出多段階複合發酵方式。此方法係將以果實類、蔬菜類、海藻類為主原料的複合乳酸菌發酵物與以蔬菜類、根菜類、種子類、菇類、果實類為主要原料的酵母發酵物混合,對其添加以穀類、豆類為主原料的麴菌發酵物,並進一步添加酢酸發酵物予以混合後,進行過濾濃縮,再進行約1年左右的後發酵而成者。藉由此種多階段複合發酵,各發酵生產物進一步由他種菌類合成代謝・轉換,研判可提升風味,同時可提高抗氧化活性等效果。As an example of a preferred method for producing the above-mentioned plant fermented products, a multi-stage complex fermentation method can be cited. This method is to mix a complex lactic acid bacteria fermented product with fruits, vegetables, and seaweed as the main raw materials with a yeast fermented product with vegetables, root vegetables, seeds, mushrooms, and fruits as the main raw materials, add a koji fermented product with cereals and beans as the main raw materials, and further add an acetic acid fermented product to mix, filter and concentrate, and then perform post-fermentation for about 1 year. Through this multi-stage complex fermentation, each fermented product is further synthesized, metabolized, and converted by other bacteria, and it is considered that the flavor can be enhanced and the antioxidant activity can be improved at the same time.

(c)有機酸組成(每100g)
(d)礦物質組成(每100g)
此植物發酵物係與天生酵素金印(日本自然發酵公司製)相同者,在以下實施例中加以使用。This plant ferment is the same as the natural enzyme Kinjiru (manufactured by Japan Natural Fermentation Co., Ltd.) and is used in the following examples.
實施例1 製造例1中調製之植物發酵物的物性: (1)最低抑菌濃度的測定 秤量製造例1中調製之植物發酵物,添加其2倍的滅菌水,滲透一夜後使成分溶出,將離心分離後的上清液以0.22μm的濾紙過濾後作為試料。使用此試料,探討對多重抗藥性革蘭氏陰性菌之MIC。 Example 1 Physical properties of the plant fermented product prepared in Example 1: (1) Determination of minimum inhibitory concentration The plant fermented product prepared in Example 1 was weighed, and twice the amount of sterilized water was added. After permeation overnight, the components were dissolved. The supernatant after centrifugation was filtered through a 0.22 μm filter paper and used as a sample. This sample was used to investigate the MIC against multidrug-resistant Gram-negative bacteria.
由此結果,植物發酵物之對多重抗藥性革蘭氏陰性菌之MIC為1/4濃度。As a result, the MIC of plant ferments against multidrug-resistant Gram-negative bacteria was 1/4 of the concentration.
(2)組合試驗 使用將各種抗菌藥之濃度梯度系列形成固相之藥劑感受性試驗孔盤(乾式孔盤榮研:榮研化學製)與多重抗藥性革蘭氏陰性菌來進行組合試驗。將其結果示於圖2。此外,各孔盤中以0、1/10或1/16添加有植物發酵物(試料),並添加一定量的多重抗藥性革蘭氏陰性菌。 (2) Combination test A combination test was conducted using a drug sensitivity test plate (Dry Plate Eiken: Eiken Chemical Co., Ltd.) in which a concentration gradient series of various antimicrobial drugs was formed into a solid phase and multidrug-resistant Gram-negative bacteria. The results are shown in Figure 2. In addition, plant fermentation (sample) was added to each plate at 0, 1/10, or 1/16, and a certain amount of multidrug-resistant Gram-negative bacteria was added.
由此結果,僅有抗菌藥時,對多重抗藥性革蘭氏陰性菌未看出其效果;以低於MIC的1/8~1/10添加植物發酵物,就美羅培南或多尼培南等碳青黴烯系,甚或頭孢吡肟等頭孢系抗菌藥,可阻止多重抗藥性革蘭氏陰性菌的增生而使MIC大幅降低。As a result, when only antibiotics are used, no effect is seen against multidrug-resistant Gram-negative bacteria; adding plant ferments at a concentration lower than 1/8~1/10 of the MIC, carbapenems such as meropenem or doripenem, or even cephalosporin antibiotics such as cefepime, can prevent the proliferation of multidrug-resistant Gram-negative bacteria and significantly reduce the MIC.
(3)縱橫交錯試劑 於組合試驗中,係針對再現性相對較高的美羅培南(MEPM)及多尼培南(DRPM),為確認植物發酵物的併用效果而進行縱橫交錯試驗。縱橫交錯試驗係於96孔孔板中對抗菌藥與植物發酵物賦予濃度梯度而分配,添加多重抗藥性革蘭氏陰性菌培養一夜,於各井孔中算出FIC index而判定併用效果。將縱橫交錯試驗的結果示於圖3。此外,就相乘/相加效果的判定,係根據下述計算式求出FIC index (fractional inhibitory concentration),將0.5以下判定為“有相乘效果”。 (3) Vertical and horizontal cross-talk test In the combination test, a vertical and horizontal cross-talk test was conducted to confirm the combined effect of plant ferments for meropenem (MEPM) and doripenem (DRPM), which have relatively high reproducibility. In the vertical and horizontal cross-talk test, antibiotics and plant ferments were distributed in a 96-well plate with a concentration gradient, multidrug-resistant Gram-negative bacteria were added and cultured overnight, and the FIC index was calculated in each well to determine the combined effect. The results of the vertical and horizontal cross-talk test are shown in Figure 3. In addition, the FIC index (fractional inhibitory concentration) was calculated according to the following calculation formula to determine the multiplicative/additive effect, and a value below 0.5 was determined as "a multiplicative effect".
[數1] FIC index=(併用時的MIC)/(抗菌藥單獨的MIC)+(併用時的MIC)/(植物發酵物單獨的MIC) [Number 1] FIC index=(MIC when used together)/(MIC of the antibiotic alone)+(MIC when used together)/(MIC of the plant ferment alone)
由此結果,僅有抗菌藥時,對多重抗藥性革蘭氏陰性菌未看出其效果;以1/8~1/10添加植物發酵物,就美羅培南或多尼培南等碳青黴烯系,甚或頭孢吡肟等頭孢系抗菌藥,可阻止多重抗藥性革蘭氏陰性菌的增生而使MIC大幅降低。As a result, when only antibiotics were used, no effect was seen on multidrug-resistant Gram-negative bacteria; adding plant ferments at 1/8~1/10, carbapenems such as meropenem or doripenem, or even cephalosporins such as cefepime, could prevent the proliferation of multidrug-resistant Gram-negative bacteria and significantly reduce MIC.
(4)硝噻吩試驗 為探討金屬-β-內醯胺酶的活性,而依循常用方法(石井良和等人, 「喀痰中β-內醯胺酶活性之測定方法的確立相關探討」, 日本化學療法學會雜誌, Vol.47, No.10,p619-622(1999))進行硝噻吩試驗。由於在植物發酵物(圖中:發酵液)的存在下,因硝噻吩的分解而發出紅色者與陽性對照相比被抑制,因此金屬-β-內醯胺酶的活性降低而使碳青黴烯系等現有的抗菌藥發揮其效力(圖4)。此外,巰機乙酸係指向來週知之試管內的金屬-β-內醯胺酶抑制劑。 (4) Nitrothiophene test In order to investigate the activity of metallo-β-lactamase, the nitrothiophene test was conducted according to the commonly used method (Ishii Yoshikazu et al., "Study on the establishment of a method for determining β-lactamase activity in sputum", Journal of the Japanese Society of Chemical Therapy, Vol.47, No.10, p619-622 (1999)). Since the red color emitted by the decomposition of nitrothiophene in the presence of plant fermentation (fermentation liquid in the figure) is inhibited compared to the positive control, the activity of metallo-β-lactamase is reduced, allowing existing antibacterial drugs such as carbapenems to exert their efficacy (Figure 4). In addition, acetic acid refers to the in vitro metallo-β-lactamase inhibitor known in the past.
