Strain A2 could heterotrophically grow on YD medium and could also autotrophically grow on inorganic medium. The heterotrophical growth rate (0.39mg/L.d) was higher than the autotrophical growth rate (0.22mg/L.d).
该菌株既能在YD培养基上异养生长,也能在无机培养基上自养生长,异养生长速率(Vmax为0 39mg L·d)明显高于自养生长速率(Vmax为0 2 2mg L .d)。
Spores of the Microsoirum fortunei (Moore) Ching were cultured in the inorganic medium and the soil respectively. Spore germination and gametophytic development were observed by microscope.
A strain named GXP04,grown with phenol as the sole source of carbon and energy,was isolated from the soil samples which was polluted by wastewater of chemical plant at Nanning suburban On the basis of observing of modality and the analysis of the 16S rDNA sequence,GXP04 was identified as Acinetobacter junii primarily The optimum temperature and pH for growth and phenol degradation were 34℃and pH 7 0,respectively
Aliquots, 0.5?g fresh cyanobacterial samples, each containing about 1×106 organotrophic bacterial cells (≡0.001?mg fresh bacteria) were incubated in inorganic medium aliquots supplied with an n-alkane.
1.Tetrahymena thermophilia wild type inbred strain B 1863-III shows increased transport activity for a group of amino acids, corresponding to those ascribed to System L, after 5 h incubation in amino acid-free inorganic medium.
This paper reports strain P5414 isolated from sewage of Fujian Sanming. It can grow in mineral media with a methanol as the sole carbon and energy source. It is not requiring growth factors and vitamins. 0. 359 g wt. /g methanol are obtained in flask. The culture conditions of strain Pun have been studied,including comparison of different methanol media,different methanol concentrations, pH, available carbon sources and nitrogen sources. Strain Pun content of crude protein is 75.1% ,amino acid 53. 6% ,nucle...
A strain that can grow with phenol as the sole source of carbon and energy, PHEA\|2, was isolated from the wastewater discharged by an oil refinery. The maximum rate of phenol degradation of PHEA\|2 is 394 nanomoles per minute per milligram of protein. Biolog Microstation Identification System was used to identify the PHEA\|2 as Acinetobacter Calcoaceticus. The sequence analysis of a 1500 bp 16?S rDNA fragment amplified from total DNA of PHEA\|2 strain by PCR showed that PHEA\|shares 98% 16?S 4DNA seque...
The effect of sucrose,thiamine,pyridoxine,glycine,glutamic acid,indoleacetic acid(IAA),kinetin and extract of pteridium aquilinum leaves on sporiparity of pteridium aquilinum were studied.The results showed that the rate and the speed of germination of the its spores could be obviously promoted.It was also shown that these substances could accelerate the formation of prothallus and sporophyte.
