【正文】 broadspectrum antifungal agent generated by the fermentation of the streptomyces natalensis,streptomyces gilvosporeus,streptomyces chattanoogensis and other can be used as biological preservatives because it has low toxicity and change food taste experiment adopts the methods of adding Fungal fermentation broth to streptomyces natalensis N5 strains to improve natamycin production of the results reveal that Fermentation broth of Penicillium chrysogenum, Aspergillus niger, Saccharomyces cerevisiae can all improve Production of natamycin has the best effect on the improvement of the synthesis of natamycin when Penicillium chrysogenum and Aspergillus niger are cultured for one ,Saccharomyces cerevisiae has the best effect of improvement when culture for three days,and when the production of natamycin is one time higher than samples without treatment of fungal fermentation broth. Key words: natamycin productivity Penicillium chrysogenum Aspergillus niger Saccharomyces cerevisiae ag an employment tribunal clai Emloyment tribunals sort out disagreements between employers and employees.

Ask your heart what it wants 傾聽(tīng)內(nèi)心 We’re often confused at the next step to take, making pros and cons lists until our eyes bleed and our brains are sore. Instead of always taking this approach, what if we engaged a new part of ourselves that isn’t usually involved in the decision making process?我們常對(duì)未來(lái)猶疑不定，反復(fù)考慮利弊直到身心俱疲。 2. Embrace the unfortable We all know what that twinge of anxiety feels like. We know how fear feels in our bodies: the tension in our necks, the tightness in our stomachs, etc. We can practice leaning into these feelings of disfort and let them show us where we need to ，也都感受過(guò)恐懼造成的生理反應(yīng)：脖子僵硬、胃酸翻騰。嫌惡過(guò)自己的怯懦，最終卻發(fā)現(xiàn)有很多 緣分 ，有很多錯(cuò)過(guò)，好像冥冥之中真的已經(jīng)注定。s plaint.
