A homothallic isolate of Fusarium solani produced red perithecia when illuminated and grown on a simple basal medium containing L-tyrosine; L-phenylalanine; or D-glucose + NaNO3 as a sole carbon and nitrogen source. Few or no perithecia formed in darkness on these media. Quantitative comparisons of perithecial formation in illuminated treatments indicated that L-tyrosine was a significantly better sole source of carbon and nitrogen than either L-phenylalanine or D-glucose + NaNO3. There was no significant difference between the responses on media containing L-phenylalanine and D-glucose + NaNO3. If dark-grown treatments were subsequently illuminated, perithecia formed on media containing L-tyrosine and D-glucose + NaNO3 but not on L-phenylalanine. The initial pH of the medium containing L-tyrosine did not seem to affect the fruiting response in illuminated cultures. A reduction in the amount of L-tyrosine in the basal medium resulted in a corresponding decrease in perithecial formation.The results are discussed in connection with a possible relationship of sexual reproduction, the light requirement, and tyrosine metabolism.

The growth conditions of a Geobacillus sp. were investigated by single-factor experiments. The strain was strictly aerobic bacterium, and could grow on hydrocarbons as the sole carbon source. The optimum carbon and nitrogen sources were 3.0% sucrose and 0.20% KNO3, respectively. The range of temperature, salinity and pH for the bacterial growth was 35-70 °C, 0-10% NaCl and 5.5-9.5, and good growth was obtained at 35-65 °C, 0.5-8% NaCl and 6.0-9.0, respectively. Particularly, the optimum temperature for the bacterial growth was between 50 °C and 60 °C. The strain had wide adaptability to the extreme conditions, and may be potentially applied to microbial enhanced oil recovery and oil-waste bioremediation technology.

Key Nodes

In this study, the metabolic network of ectoine by Halomonas venusta DSM 4743 was established. The key nodes to influence the ectoine fermentation in metabolic flux and the basis during optimal control of fermentation process were investigated. The results showed that G6P, α-KG and OAA nodes were the key factors to influence the synthesis of ectoine. The metabolic flux distributions at the key nodes were significantly improved and ectoine concentration was enhanced in ectoine fermentation by adopting monosodium glutamate as the sole carbon and nitrogen sources, feeding monosodium glutamate and supplying oxygen limitedly. The batch fermentation was carried out in 10 L fermentor , the concentration and yield of ectoine was 8.4 g/L and 0.1 g/g, respectively, which were increased by 2.8 and 2 times, by comparison with batch fermentation using glucose as carbon source.
