Abstract: Citrus unshiu “Guoqing No.1” was used as material for elucidating the effect of Kloeckera apiculata suspension post-harvest treatment on preventing fruit decay during storage period. The result showed that K. apiculata preparation of 2×106CFU/mL (CFU, cloning forming unit) significantly reduced the development of decay caused by green mold, blue mold and stem rot, showing the same effect of carbendazim treatment after storage period of 100 days, and the disease incidence was controlled under 1%. The antagonist population was between 3.5×105CFU/mL and 1.7×107CFU/mL in citrus fruit, and increased 1.7×107CFU/mL after 40 days storage, and then stabilized for the remaining storage period. After storage at 5℃ for 100 days, K. apiculata strain 34-9 did not alter any quality parameters of fruit. During storage, the change of relative electrical conductivity (REC) showed a coordinate tendency with malondlaldehyde (MDA) content, which kept continuously growing from the beginning to the end of the storage. In the storage period of 25 days, the REC value and MDA content of the treatments were all significantly lower than those of water treatment, but had no obvious difference from those of carbendazim treatment. K. apiculata strain 34-9 had no effect on the enzyme activity of super oxide dismutase (SOD), but significantly improved peroxidase (POD) activity after 100 day storage.

Abstract: 本实验以温州蜜柑"国庆一号"为试材,研究了柠檬形克勒克酵母Kloeckera apiculata悬浮液处理对柑橘果实采后防腐保鲜效果及相关酶的影响.结果表明,贮藏100d后,2×106CFU/mL(CFC表示菌落形成单位)的酵母菌液能有效地抑制青霉、绿霉和蒂腐病等贮藏期病害的发生,柑橘果实的腐烂率控制在1%以下,效果显著高于清水对照,与多菌灵相当;柠檬形克勒克酵母在柑橘果皮上的数量在3.5×105CFU/mL-1.7×107CFU/mL之间,在贮藏40d后最大值达到1.7×107CFU/mL,随后保持在106CFU/mL左右,100d贮藏结束后,品质分析表明,柠檬形克勒克酵母处理对柑橘品质没有不良影响.在整个贮藏期细胞膜透性与丙二醛(MDA)含量变化相对应,均呈上升趋势,在贮藏25d左右时酵母菌液处理和多菌灵处理的细胞膜透性与MDA含量均显著低于清水对照,而前二者之间无差异.酵母菌液对超氧化物歧化酶(SOD)活性没有诱导作用,而在贮藏后100d左右对过氧化物酶(POD)活性有诱导作用.

无机氮源对出芽短梗霉发酵普鲁兰多糖分子量的影响

- , 2017, DOI: 10.13982/j.mfst.1673-9078.2017.5.034
Abstract: 以出芽短梗霉(Aureobasidium pullulans)CGMCC No.11062为出发菌株,研究五种无机氮源对普鲁兰多糖产量、结构、纯度及分子量的影响。结果表明:无机氮源种类对普鲁兰多糖产量和分子量产生显著影响,未影响普鲁兰多糖结构和纯度。其中,以硫酸铵(1.5 g/L)为唯一氮源时普鲁兰多糖产量达到32.84 g/L,重均分子量(Weight-average Molecular Weight,Mw)最大,为799823 ku。硫酸铵浓度对普鲁兰多糖的产量和分子量影响显著,而未显著影响普鲁兰多糖结构。随着硫酸铵浓度的增加,普鲁兰多糖产量和分子量同时增加;当硫酸铵浓度为1.5 g/L时,普鲁兰多糖的产量出现最大值,为32.45 g/L;而当硫酸铵浓度为2.1 g/L,普鲁兰多糖重均分子量(Mw)最大,达到1236958 ku。所有制得的普鲁兰多糖纯度在95%~99%之间。这些研究可为不同分子量普鲁兰多糖生产提供技术指导。
The effects of five types of inorganic nitrogen sources on the yield, structure, purity, and molecular weight of pullulan were studied using Aureobasidium pullulans CGMCC No. 11062 as the parental strain. The results showed that the yield and molecular weight of pullulan were significantly influenced by the types of inorganic nitrogen source, whereas the structure and purity of pullulan were not affected. When ammonium sulfate (1.5 g/L) was used as the sole nitrogen source, the yield of pullulan was 32.84 g/L, and the maximum weight-average molecular weight (Mw) of pullulan (799823 ku) was obtained. Furthermore, the yield and molecular weight of pullulan were significantly influenced by the concentration of ammonium sulfate, which did not significantly affect the structure of pullulan. With increasing concentration of ammonium sulfate, the yield and molecular weight of pullulan increased simultaneously. The maximum yield of pullulan (32.45 g/L) was reached at 1.5 g/L ammonium sulfate, and the peak Mw of pullulan (1236058 ku) was obtained at 2.1 g/L ammonium sulfate. The purity of pullulan produced from all experiments was between 95% and 99%. These studies could provide technical guidance for the production of pullulan with different molecular weights.
