Cellobiase production was studied in solid state fermentation by a selected Aspergillus niger strain. The effects of culture time, temperature, initial pH value and water content of the substrate on cellobiase synthesis were discussed. It was found that the cellobiase activity could reach 430.56 IU/g dry koji under suitable fermentation conditions. The synergistic action between the cellobiase enriched koji produced by A. niger and the cellulase koji by Trichoderma reesei was obvious during the hydrolysis of waste pulp. When the two kinds of koji were mixed and the ratio of cellobiase activity to FPA is about 0.4, no cellobiose accumulated in the hydrolysate, and the high hydrolysis efficiency (90.7%) was obtained.

A preliminary study on solid state fermentation (SSF) with Penicillium sp PT95 for carotenoid production was performed.The results showed that the production of carotenoid in sclerotia of PT95 was more efficient in corn meal medium than in either wheat bran medium or cottonseed hull medium.Addition of nitrogen and carbon sources as well as vegetable oil to media was required for increasing the dry weight of sclerotia and carotenoid yield.Among several tested compounds for nitrogen and carbon sources,sodium nitrate and maltose were the best.Through orthogonal experiments,the optimum culture medium was obtained by supplement of NaNO 3 3g,maltose 10g,soybean oil 2.5g to per liter of salt solution.Under the optimum culture conditions,the sclerotia dry weight increased from 5.36g to 9.70g per 100g dry substrate,the carotenoid yield from 2149 μg to 5260μg per 100g dry substrate,the proportion of β carotene in carotenoids from 61.4% to 71.3%.

本文对青霉Peniciliumsp.PT95菌株在固态发酵条件下菌核内产生类胡萝卜素进行了初步研究。结果表明,在3种固态发酵培养基中,玉米粉培养基(SMA)比麸皮培养基和棉籽壳培养基更适合于PT95菌株固态发酵产生类胡萝卜素。为了增加菌核干重和提高类胡萝卜素产率,SMA中需要添加氮源、碳源和植物油。在所试的各种氮、碳源中,以硝酸钠和麦芽糖效果最佳。通过正交试验确定了在培养基盐溶液中添加硝酸钠3g/L,麦芽糖10g/L,豆油25g/L能使菌核干重由536g/100g提高到970g/100g(干料);类胡萝卜素产率由2149μg/100g提高到5260μg/100g(干料);β胡萝卜素在类胡萝卜素中的含量由614%提高到713%。
