Methyl (3-hydroxy-4-(2-hydroxy-6-methylheptan-2-yl)benzoyl)glycinate (1), a new sydonic acid derivative with glycinate, together with sydonic acid (2), sydowic acid (3), and 7-deoxy-7,14-didehydrosydonic acid (4), were isolated from a marine-derived Aspergillus sydowii strain CUGB-F126. Their structures were elucidated by spectroscopic analysis, including high-resolution mass spectroscopy, and 1D and 2D NMR techniques. All of these compounds did not show inhibitory activity against Staphylococcus aureus and Candida albicans.

We studied the influences of enzyme concentration (0.02–0.1%. w/v), temperature (40–70 °C), pH (4.5–8), lactose concentration (5–40%, w/v) and foam architecture reaction media on formation of GOS. The total GOS increased from about 7 to 23 (wt.% of initial lactose) with an increase in lactose from ...

The objective of the current study is to investigate the hydrolysis of pectinaceous matter in guava juice and to model the depectinization kinetics using commercial pectinase from Aspergillus niger. The procedure involves enzymatic treatment of guava juice at 45 °C with enzyme concentration (% w/w) 0.033, 0.055, 0.078 and 0.1. The degree of hydrolysis of pectinaceous matter and the rate of enzymatic reaction are determined. The results show an increase in the degree of hydrolysis with time for each enzyme concentration. Depectinization kinetics reveal allosteric behavior and is modeled using the Hill Equation. The...

Chronic Pulmonary aspergillosis (CPA) is a well described spectrum of the disease caused by the fungi belonging to the Aspergillus species first described in 1842 as a complication of tuberculous cavities. Advances in thoracic surgery and advances of antifungal therapy in the late 1900s led to the first cure[1]. Aspergillosis is a disease process that varies based on the level of immunosupression; angioinvasive aspergillosis is present in a setting of profound immunosupression and allergic bronchopulmonary aspergillosis in a hyperimmune setting.

Abstract Azole‐resistant Aspergillus fumigatus (ARAF) has been reported in patients with chronic obstructive pulmonary disease (COPD) but has not been specifically assessed so far. Here, we evaluated ARAF prevalence in azole‐naïve COPD patients and their homes, and assessed whether CYP51A mutations were similar in clinical and environmental reservoirs. Sixty respiratory samples from 41 COPD patients with acute exacerbation and environmental samples from 36 of these patient's homes were prospectively collected. A. fumigatus was detected in respiratory samples from 11 of 41 patients (27%) and in 15 of 36 domici...

Abstract Strategies for achieving global food security include identification of alternative feedstock for use as animal feed, to contribute towards efforts at increasing livestock farming. The presence of theobromine in cocoa pod husks, a major agro-waste in cocoa-producing countries, hinders its utilisation for this purpose. Cheap treatment of cocoa pod husks to remove theobromine would allow largescale beneficial use of the millions of metric tonnes generated annually. The aim of this study was to isolate theobromine-degrading filamentous fungi that could serve as bioremediation agents for detheobromination of ...

Publication date: December 2017 Source:Microbial Pathogenesis, Volume 113 Author(s): Samah A. El-Debaiky The present study represents, for the first time, the detailed studies about the hyphal interactions of Aspergillus piperis, as a new antagonist, against some isolated plant pathogenic fungi (Alternaria alternata, Alternaria solani, Botrytis cinerea, Sclerotium cepivorum and Sclerotinia sclerotiorum) in vitro. The bio-controlling capability of A. piperis against the tested phytopathogens was tested using the dual culture method. This experiment revealed that A. piperis had antagonistic activity and reduced the growth o...

Alwethairi The biological activities; antimicrobial, antioxidant and anticancer, of the red algae Galaxaura rugosa and Liagora hawaiiana were determined. The total ethanol, lipoidal matters, chloroform, n-butanol, aqueous extracts and powder of both algae showed and bacterial and antifungal activities. However, the chloroform extract of Galaxaura rugosa showed antibacterial activity against Klebsiella pneumoniae (24 mm, 0.15 mg/ml) higher than gentamycin (23 mm, ...
