Packing, sterilizing, a kind of rhyme scheme in Chinese operas serving as the prelude to a complete score for voices, standby fluid nutrient medium is identical with solid medium composition formula, without agar powder.
Paper relics mildew sample：Late Qing Dynasty rice paper 6cm × 10cm is cut, is laid in after sterilizing on culture dish, uses sprayer
The spore suspension of penicillium chrysogenum mould is sprayed in rice paper surface, incubator and cultivates 10d, during Spawn incubation is bred, every
12h sprays to be taken out after sterile distilled water, preferable bacterial plaque to be formed, is gently handled surface mycelia with soft hairbrush, is divided and be placed in
Shady place is dried in the shade 24h, and hermetically drying box is preserved.
(2) cleaning method and detection
Cleaning method：Pattern is clipped between two blocks of sheet glass and is fixed, is immersed in paper relics mildew cleaning agent,
In soaking 15-90min at 20-40 DEG C, residual cleaner then is removed with siphon method, is spontaneously dried, performance survey is carried out after 16h
Examination.
Detection：
1. pulling force damage check：According to GB/T 12914, tested and cleaned using HK202E micro computer tensile strength tester
The maximum pull that paper is born before fracturing afterwards.
2. whiteness is detected：According to GB/T 7975-2005, the reflectivity calculating whiteness under 460nm wavelength is poor, with light splitting
The blank of photometer is used as control.
3. acid-base value is detected：According to GB/T 1545-2008, the pH of extract is determined using pH meter.
4. glossiness is detected：According to GB8941.1.3, the light of same point before and after mildew cleaning is determined using HK vancometers
Damp angle value.
1st, the influence of biology enzyme content
In cleaning agent, 0.5% AEO, the addition for adjusting papain are respectively 1%, 3%,
4%, 5%, water surplus, in soaking 30min at 35 DEG C, as a result such as Fig. 1-4.
From Fig. 1-4, with the rise of Papain enzyme concentration, mechanical strength and pattern acid-base value without significant changes,
And whiteness then has obvious rising, ascensional range diminishes after concentration reaches 3%, almost unchanged, and glossiness has declined, and works as quality
Being handled when fraction is more than 4% after pattern dries in the shade has a little powdered substance to separate out, and influences the glossiness of pattern.It is therefore preferred that
The 3% of papain content.
2nd, the optimization of soaking temperature
Cleaning agent uses 3% papain, 0.5%AEO9, water surplus prescription, respectively at 20 DEG C, 35 DEG C, 50 DEG C, 65
30min is soaked at DEG C.As a result such as Fig. 5-8.
As shown in Fig. 5-8, with the rise of soaking temperature, whiteness and glossiness are increased significantly after phenomenon, 35 DEG C
Elevation amplitude diminishes, and pH is then without significant changes, but tension intensity but significantly declines, and 65 DEG C of ratios, 35 DEG C of tension intensitys decline
35.6%.In addition soaking temperature can also influence the activity of protease, and the enzymatic activity of every kind of enzyme has its optimum temperature, in most thermophilic
Under degree, active highest, when deviateing optimum temperature, activity diminishes.65 DEG C of papain activity highests, go mould effect most in theory
It is good, but to can bear maximum pull relatively low for 65 DEG C of patterns, while temperature is too high to accelerate paper relics aging, especially it is non-fibre
The aging of the plain composition of dimension, preservation long-term to pattern and storage have negative effect.So determining between influence enzyme activity and aging speed
Equilibrium temperature be just particularly important.Comprehensive analysis, it is determined that optimal soaking temperature is 35 DEG C.
3rd, the optimization of soak time
Cleaning agent uses 3% papain, 0.5%%AEO9, water surplus prescription, at 35 DEG C, soaks respectively
15min, 30min, 60min, 90min.As a result such as Fig. 9-12.
From Fig. 9-12, when soak time extends to 30min by 20min, whiteness improves 2.6, and glossiness and pulling force are strong
Degree is without too big difference；Whiteness rises and tended to be steady after 30min, and glossiness then drops to 90min's by the 6.94 of 30min
6.531, tension intensity declines also more substantially, and pH is not influenceed then by soak time.Mildew pattern is compounded in biology enzyme and cleaned
Agent soak time is longer, and tension intensity reduction amplitude is bigger, is due to that soak time is longer, cellulosic degree of polymerization is got in paper
Small, tension intensity is naturally lower.Again because biology enzyme can not only decompose the protein in mildew, also paper relics are made in itself
Into influence, so on the premise of cleaning performance is ensured, should try one's best shortening soak time.Comprehensive paper is in different soak time bars
Under part, the whiteness of pattern, glossiness, tension intensity, the situation of pH four indices, with papain and AEO9Synergy
30min, cleaning index is best.
The present embodiment, by simulating mildew on paper relics, pawpaw egg is chosen for the composition of amino acid in mildew composition
White enzyme and AE09Progress compatibility is made biology enzyme compounding cleaning agent and simulation mildew is cleaned, and by comparing pH, whiteness, light
The change of the indexs such as damp degree, tension intensity is estimated to mildew cleaning performance.As a result show, papain and AE09Collaboration
Cleaning performance is optimal, and this cleaning agent cleaning condition is optimized, find to use mass fraction for 3% papain and AEO9It is multiple
With system, 30min best results are soaked at 35 DEG C.Pattern whiteness rises 5.58 after cleaning, and glossiness improves 0.33, pH risings and connect
Weakly acidic pH, the tension intensity of pattern is without significant difference after tension intensity is cleaned with distilled water.
It is as shown in figure 13, for the Penicillium chrysogenum mildew of paper relics, using 3% papain and 0.5%AEO9's
Prescription, at 35 DEG C, after immersion 30min, natural cooling is dried, and the removal effect of mildew is observed after 16h, as seen from Figure 13, is gone
