Abstract:
The isolate XGH2321,which isolated from the rhizospheric soil of Rhizophora stylosa Griff in Dongzhaigang Mangrove Nature Reserve in China,was identified as a fungus in the genera of Penicillium based on its morphological characteristics and internal transcribed spacer(ITS) sequence analysis.After in-oculated in the modified CzapeK-DoX medium(consisted of 4% corn steep,0.3% NaNO3,0.05% KCl,0.1% K2HPO4,0.05% MgSO4,pH 7.4,9% salinity),and cultured under the condition of 28?C in a rotary shaker at 160 r/min for 7 days,the extracts of ethyl acetate and water-soluble from the fermentation broth showed the apparent antibacterial activities against the growth of Staphylococcus aureus,Sarcina lutea,and Bacillus subtilis with the minimum inhibitory concentration(MIC) of 800 ?g/mL and 400 ?g/mL,respectively.While at the same time,these two extracts could also suppress the growth of the plant pathogen,Rhizoctonia solani with MIC of 400 ?g/mL and 200 ?g/mL,respectively.
