Fungal esophagitis (FE) is caused by fungal invasion of the esophageal mucosa. Under endoscopy, mucosa shows edema, congestion, erosion, and ulceration, bleeds easily when touched, surface covered with small white spots like "bean curd residue". Clinical cases showing typical FE under endoscopic imaging but negative mucosal brush (referred to as suspected FE) have increased difficulty challenge clinical diagnosis treatment. At present, flora case has not been thoroughly studied. To characterize in FE, normal controls (NCs), identify marker species improve detection FE. This was a case-control study. A total 19 patients 16 10 NCs were selected endoscopy. The cell samples each group sequenced internal transcribed spacer (ITS) 1 analyzed bioinformatics.

Abstract Biodiesel is a renewable fuel that can be produced from range of organic and feedstock including fresh or vegetable oils, animal fats, oilseed plants. In recent years, the lignin-based aromatic wastes, such as various waste polymers agriculture, dye wastewater textile industry, have attracted much attention in academia, which uniquely selected potential for biodiesel product converted by yeast cell factory technology. This current investigation indicated highest percentage lipid accumulation achieved high 47.25% an oleaginous strain, Meyerozyma caribbica SSA1654, isolated wood-feeding termite gut system, where its synthetic oil conversion ability reach up to 0.08 (g/l/h) fatty acid composition cells represents over 95% total acids are similar oils. Clearly, use yeasts, termites, synthesizing lipids aromatics clean, efficient, competitive path achieve "a sustainable development" towards production. However, lacking potent yeasts transform aromatics, unknown metabolic regulation mechanism presented natural fundamental challenge we face development. Under this scope, review has proposed novel concept approach strategy utilization convert wastes substrate transformation. Therefore, screening robust strain(s) system with set desirable specific tolerance characteristics essential. addition, reconstruct pathway/network maximize transformation rate applications “omics” technologies biology approach, work agenda will also include analyze genome characteristics, develop new base mutation gene editing technology, well clarify influence insertion position compounds other biosynthetic pathways industrial chassis on expressional level stability. With these unique designs running advanced biotech approaches, pathway using developed potentially constructed, integrated optimized, suggesting hypothesis utilizing technically promising applicable near future.
