The optimization of NK liquid fermentation was studied in this paper. The results showed that the optimal fermentation medium is nutrition meat broth,the optimal fermentation time 24 h,and fermentation temperature 30℃.
In order to optimize technology for liquid fermentation and polysaccharide extraction of Grifola frondosa,according to experimental data the response surface model using biomass of mycelia as response value was established and the fermentation technology was optimized as follows: air-flow 1.4∶1(V/V),pH 6.0.The biomass of mycelia was fitted by Radial Basis Function(RBF).
The paper has studied the conditions of marine fungus #34,which is separated from the mangrove in the Yueqing Bay. The marine fungus #34 produces amylases by submerged fermentation under the conditions. The results shows that the optimum conditions are as followed:fermentation time of 95h, fermentation temperature of 30℃and initial pH of 5.8 and salinity of I of the media.
After that, a solid state and liquid state fermentation procedure was conducted over these 4 strains and strain F10 demonstrated more desired property in comparison with strain AS3.3711, which was served as the standard.
The production of cellulase-free end oxylanase by the thermophilic fungus Thermomyces lanuginosus was investigated insemisolid fermentation and liquid fermentation.
This substrate was adequate for growth and aroma production; the concentration obtained using SSF was higher than using liquid fermentation process.
Through the methods of organic solvent extraction, thin layer chromatography (TLC) and column chromatography, compound I was isolated, purified from the liquid fermentation metabolites of the taxoid-produced endophytic fungi (Altemaria.
Through thin layer chromatography (TLC), liquid fermentation metabolite of the strains was determined, and four strains (Alternaria altemata (Fr.) Keissler var.taxi Y.
The determination result of thin layer chromatography (TLC) showed that the liquid fermentation metabolites of the strains could not react positively with taxoids developer- the vanillic aldehyde and dilute bismuth potassium iodide.
was carried out during solid-state and submerged fermentation using different carbon sources and crude enzymes were characterized.
The growth of nonsporulating mycelial fungi INBI 2-26(+), a producer of laccase; INBI 2-26(-), a producer of cellobiose dehydrogenase; and their mixed culture on lignin-carbohydrate substrates under conditions of submerged fermentation was studied.
Submerged fermentation experiments were carried out to study the stimulating effects of the surfactant Span 20 on the growth of Aspergillus niger XP mutant and oxalic acid production from the post-refining fatty acids.
Hyperproduction of l-glutamate oxidase in submerged fermentation of Streptomyces sp.
Although submerged fermentation has been universally used as the technique of fermentation, attempts are being made to develop solidstate fermentation technology also.
