• Estimation of the proportion of undescribed fungal taxa is an issue that has remained unresolved for many decades. Several very different estimates have been published, and the relative contributions of traditional taxonomic and next-generation sequencing (NGS) techniques to species discovery have also been called into question recently. • Here, we addressed the question of what proportion of...

Wheat/soybean rotation is an important double-cropping system in the Huang-Huai-Hai plain of China. Continuous soybean cropping could cause soil quality deterioration and plant growth inhibition. However, effects continuous wheat/soybean on rhizosphere microbes remain largely unknown. In this study, we compared yield microbial community between winter wheat/summer (W/S) with two harvests one ye...

Arachidonic acid is an essential fatty acid in human nutrition. In the present study, production of arachidonic acid by Mortierella alpina CBS 754.68 was evaluated in submerged fermentation. The fermentation variables were selected in accordance with the PlackettBurman (PB) design and further optimized via response surface methodology (RSM). Five significant variables, namely glucose, yeast ext...

The filamentous fungus, Mortierella alpina, accumulates complex lipids relatively rich in arachidonic acid (C(20:4) Delta(5,8,11,14)). The lignan, sesamin, has been used to reduce arachidonic acid production by specifically inhibiting Delta(5)-desaturation [Shimizu, Akimoto, Shinmen, Kawashima, Sugano and Yamada (1991) Lipids 26, 512-516]. Microsomal membrane preparations from M. alpina exhibit...

Conventional irrigation methods decrease greenhouse soil aeration, which leads to restricted root growth and reduced fungal abundance in grapes. In this study, aerated equipment was used investigate the effects of on biomass accumulation, growth, community structure grape seedlings. The results show that significantly increased length, surface area, volume, number tips by 38.5%, 32.1%, 62.1%, 2...

In the present study, the oleaginous fungus Mortierella alpina CBS 754.68 was screened for arachidonic acidproduction using inexpensive agricultural by-products as substrate. Four oilcakes were analysed to choose the best substrate among them. Sunflower oilcake was the most effective substrate for ARA production followed by soybean, colza and olive oilcakes. In the next step, seven variables in...

a 34-year-old man was admitted because of severe shock to the intensive care unit (ICU) at University Hospital of Liege (Liege, Belgium) on day 10 after nonfamilial hematopoietic stem cell transplantation (HSCT). X-linked gp91phox gene mutation chronic granulomatous disease (CGD) had been diagnosed when he was 4 years of age. The patient had a history of recurrent pulmonary aspergillosis (Asper...
