Biosurfactant production by Bacillus subtilis B30 and its application in enhancing oil recovery.
The results are indicative of the potential of the strain for the development of ex situ microbial enhanced oil recovery processes using glucose or date molasses based minimal media and the biosurfactants were stable over wide range of pH, salinity and temperatures. Expand
Biosurfactant production by Bacillus subtilis B20 using date molasses and its possible application in enhanced oil recovery.
Abstract This study highlights the use of low-cost agro-industrial raw material – date molasses for fermentative production of biosurfactants. Date palm ( Phoenix dactylifera L.) is the primary cropExpand
Fungi and aflatoxins associated with spices in the Sultanate of Oman
Of the seven spices studied, clove was found to be the least contaminated, while cumin was the most contaminated, and the moisture content of most of the spices was below the maximum standard limit. Expand
Effect of Hibiscus sabdariffa extract and Nigella sativa oil on the growth and aflatoxin B1 production of Aspergillus flavus and Aspergillus parasiticus strains
The results suggest that H. sabdariffa calyx and N. sativa oil extracted from seeds had metabolic effects on aflatoxin biosynthesis pathway of both Aspergillus species and can be used as an effective biocontrol and non-toxic biopreservatives in food industry against a Flatoxin contamination. Expand
Mycoflora and Aflatoxins in Soil, Eggshells, and Failed Eggs of Chelonia mydas at Ras Al-Jinz, Oman
The growth of fungi on turtle eggs and secretions of mycotoxins may affect embryonic development and possibly contribute to the green turtle egg mortality. Expand
Sophorolipids Production by Candida bombicola ATCC 22214 and its Potential Application in Microbial Enhanced Oil Recovery
The potential of SPLs in enhancing oil recovery was tested using core-flooding experiments under reservoir conditions, where additional 27.27% of residual oil (Sor) was recovered and confirmed the potential of SPLs for applications in microbial enhanced oil recovery. Expand
First report of Albizia lebbeck dieback caused by Scytalidium dimidiatum in Oman
This is the first report of the fungus in Oman and on A. lebbeck, T. populnea, D. regia and P. petrocarpum, the strain of this fungus has not been found to cause human disease in Oman. Expand
Biodegradation of crude oil and n-alkanes by fungi isolated from Oman.
Ten fungal species isolated from tar balls collected from the beaches of Oman were tested for their abilities to grow and degrade n-alkanes and crude oil and the correlation coefficient of biomass and oil utilization was not statistically significant, but significant for Aspergillus niger, As pergillus terreus and P. chrysogenum.

Fungi associated with black tea and tea quality in the Sultanate of Oman
The results showed that black tea is contaminated by fungi that might constitute health hazards for humans and the post harvest contamination of tea could be eliminated or reduced if processing is conducted under more hygienic conditions. Expand
Production, Characterization, and Application of Bacillus licheniformis W16 Biosurfactant in Enhancing Oil Recovery
The core flood experiments showed that the biosurfactant was able to enhance the oil recovery by 24–26% over residual oil saturation (Sor) and highlight the potential application of lipopeptide biosurfacts in wettability alteration and microbial EOR processes. Expand
