Laccase production by a white-rot fungus Coriolus versicolor was studied under submerged fermentation (condition). The optimal fermentation parameters were as follows:carbon source 1.1 g/L sucrose combined with 1.1 g/L glucose,nitrogen source 1.88 g/L bean cake powder,culture temperature 30 ℃ and initial pH value 4.5.The activity of laccase reached 18.2 U/mL.
In this paper,we studied the liquid submerged fermentation process conditions for Tremella facifamis Berk As5.526.Through one-factor experiments,we determined that 0.5% concentration of β-CD thicker is added to liquid medium;
(2) After deep liquid fermentation medium optimized, the composition of best culture medium for Trametes trogii included: 2.0% potato, 0.3% KH_2PO_4, 0.3% MgSO_4, 0.001% V_B, 0.005% CaCl_2, 1.0% wheat bran, 0.6% yeast-extract, 0.001mol/L L-Tyrosine.
Venting would promote the growth of fruitbody. Secondly, in experiment of deep liquid fermentation of Cordyceps militaries, the optimum liquid culture condition was: rice meal 4%, soybean meal 2%, KH2PO40.15%, MgSO4.7H200. 2%.
The effect of pH value, temperature and soluble oxygen on the deep liquid fermentation of cellulose-enzyme with a trichoderma green were studied. In a 10-litre aerate fermentation jar with machine mix round,the dosage of inoculation was 10%. The pH value,temperature and soluble oxygen were controlled step by step.
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.
Solid-phase fermentation has been found to have a much higher productivity than the popular liquid submerged fermentation in producing cellulase enzymes.
Molecular studies were performed to establish the causes of the superior lovastatin productivity of a novel solid-state fermentation (SSF) process, in relation with liquid submerged fermentation (SmF; 20?mg/g vs.
The level of phytase production on solid substrate was higher than that obtained by submerged liquid fermentation.
An increase of ≈423-fold in xylanase production and complete suppression of CMCase production was achieved over submerged liquid fermentation.
Eleven strains were considered good producers under conditions of submerged liquid fermentation (shaken cultures) and solid-state fermentation.
The fermentation period of YY-5 in solid state fermentation (SSF) shortened to 4?days compared with 5?days of submerged liquid fermentation (SmF) and the maximum laccase activity was 678.1?IU?g-1 substrate.
