For the conversion of cellulose into biofuel by microorganisms is being studied intensively. This research isolate and screen efficient cellulolytic microorganism from bamboo forest soil based on growth rate on CMC plate, the size of transparent circle, disintegration effect of filter paper, and CMC enzyme activity assay. As a result, efficient cellulose-decomposing fungus J6-1 was obtained. The strains possessed higher filter paper degrading ability and CMC enzyme activity, disintegrating the filter paper into 42.3% at the 5th days and reaching the highest CMC enzyme activity 6.87IU/mL after 120 hours of shake flask fermentation. Strains J6-1 is preliminarily identified asPenicilliumby morphological observation and a great potential cellulolytic strains.

Shake Flask Fermentation

To improve the yield of the Pseudomonas strain N1 in the fermentation culture medium screened from the biofilm of BAF reactor, the optimal shake flask fermentation conditions for Pseudomonas N1 were determined by single factor test and orthogonal test. The composition of optimal fermentation culture medium was as follows: nitrate of potash of 4 g/L, sodium succinate of 26.1 g/L, KH2PO4 of 4.0 g/L, MgSO4·7H2O of 1 g/L, KCl of 1 g/L. The cell concen- tration could reach 9.08 g/L under the conditions. Fermentation was performed for 36h in a 250ml shake flask containing 70mL medium at 1% inoculums volume and initial pH value 7.0. The cell concentration could reach 12.86 g/L which was 2.5 fold higher than that under the original conditions. Simultaneous nitrification and denitrification could be achieved to alleviate the pollution of nitrogen in the wastewater by adding the microbial inoculums into the common aerobic nitrifica- tion sludge.

Several 2-amino-3H-phenoxazin-3-ones, including cinnabarin, were obtained from the appropriate o-aminophenols by oxidative dimerization on thin-layer plates in air. Shake-flask fermentation of Pycnoporus cinnabarinus also gave cinnabarin.

Shake Flask Fermentation

By applying a fed-batch strategy, production of Penicillium occitanis mannanases could be almost doubled as compared to a batch cultivation on acacia seeds (76 versus 41 U/mL). Also, a 10-fold increase of enzyme activities was observed from shake flask fermentation to the fed-batch fermentation. These production levels were 3-fold higher than those obtained on coconut meal. The high mannanase production using acacia seeds powder as inducer substrate showed the suitability of this culture process for industrial-scale development.

Fcc Metal

Prolonged electron irradiation of metals at elevated temperatures usually leads to the formation of large interstitial-type dislocation loops. The growth rate of the loops is proportional to the total cross-section for atom displacement,which is implicitly connected with the threshold energy for atom displacement, Ed . Thus, by measuring the growth rate as a function of the electron energy and the orientation of the specimen with respect to the electron beam, the anisotropy of Ed can be determined rather precisely. We have performed such experiments in situ in high-voltage electron microscopes on Ag and Au at 473K as a function of the orientation and on Au as a function of temperature at several fixed orientations.Whereas in Ag minima of Ed are found close to <100>,<110>, and <210> (13-18eV), (Fig.1) atom displacement in Au requires least energy along <100>(15-19eV) (Fig.2). Au is thus the first fcc metal in which the absolute minimum of the threshold energy has been established not to lie in or close to the <110> direction.
