Recent Advances in Petroleum Microbiology
The physiological responses of microorganisms to the presence of hydrocarbons, including cell surface alterations and adaptive mechanisms for uptake and efflux of these substrates, have been characterized and used to investigate the dynamics of microbial communities in petroleum-impacted ecosystems.

Omega-3/6 fatty acids: Alternative sources of production
Various microbiological and enzymatic methods for synthesis of PUFAs are discussed and marine protists and dinoflagellates are the rich sources of DHA, whereas microalgae like Phaeodactylum and Monodus are good sources of EPA.
Detoxification of sugarcane bagasse hydrolysate improves ethanol production by Candida shehatae NCIM 3501.
Sugarcane bagasse hydrolysis with 2.5% (v/v) HCl yielded 30.29g/L total reducing sugars along with various fermentation inhibitors such as furans, phenolics and acetic acid with maximum ethanol yield from ion exchange treated hydrolysate.
Developments in the use of Bacillus species for industrial production.
Developments from the understanding of the complex protein translocation machinery of Gram-positive bacteria should allow the resolution of current secretion challenges and make Bacillus species preeminent hosts for heterologous protein production.
Microbial Cellulases and Their Industrial Applications
Scientific and technological developments and the future prospects for application of cellulases in different industries are discussed in this paper.
Physiological aspects. Part 1 in a series of papers devoted to surfactants in microbiology and biotechnology.
Biosurfactants play an essential natural role in the swarming motility of microorganisms and participate in cellular physiological processes of signaling and differentiation as well as in biofilm formation.
Surfactants in microbiology and biotechnology: Part 2. Application aspects.
Beneficial applications of chemical surfactants and biosurfactants in various industries are discussed in this review.
Accelerated biodegradation of petroleum hydrocarbon waste
An accelerated process has now been developed which can be completed in 10–12 days and up to 99% of total petroleum hydrocarbons are degraded and the sludges are converted from hazardous to non-hazardous according to the United States EPA's toxicity characteristic leachate procedure criteria.
Production of Crude Cellulase and Xylanase From Trichoderma harzianum PPDDN10 NFCCI-2925 and Its Application in Photocopier Waste Paper Recycling
This paper implies production of cellulase and xylanase enzyme using a potent strain of Trichoderma harzianum for the efficient deinking of photocopier waste papers without affecting the strength properties with improved drainage as an additional advantage.
