Environmental biotechnology exploits living organisms (plant, bacteria, fungi, etc) in various applications of waste treatment and remediation of pollutants. The organisms that demonstrate the potential to utilize the wastes or pollutants as food are naturally found in the environment. Rapid development in genetic technology also assists in introducing genetically modified organisms with enhanced capability to degrade wastes or pollutants. It has been proven that environmental biotechnology can provide safer methods of cleaning hazardous wastes compared to conventional methods since it uses natural agents.

Marine Biotechnology Task Force Report
Marine biotechnology is a rapidly growing area that is recognised, by policy makers and
the enterprise sector, as offering significant potential to develop market opportunities for
new products and processes by enabling greater utilisation of marine biological resources.
Current research funding activity, supporting efforts to create a sustainable bioeconomy, is
likely to lead to a growth in marine biotechnology research and commercial activities. Irish
and international financial support for this research is aimed at as yet largely unexplored
and underexploited marine resources for use as food, functional foods and nutraceuticals;
cosmetics and cosmeceuticals; human and animal health – including pharmaceuticals,
biocompatible materials and medical devices; materials technology; environmental
bioremediation; and marine model organisms, including the use of marine derived
materials in bioprocessing. Research within these areas has resulted in an array of new
products and processes which offer benefits to society and support economic growth.
The Marine Institute established a Task Force to advise on the steps required to strengthen
Ireland’s capability to use marine biotechnology to exploit the value of its extensive
marine bioresources. The Task Force, comprising academic and industry members,
considered the various national strategies and plans for science, technology, research
and economic development, and identified market opportunity areas and Irish marine
biotechnology research capabilities. In supporting the work of the Task Force, the Marine
Institute completed a number of information-gathering exercises to fill various knowledge
gaps identified by the Task Force. Following the preparation of a draft report, the Task
Force, with the support of the Marine Institute, held a workshop attended by researchers
and companies. This final report of the Task Force takes account of feedback from this
workshop in developing its recommendations

Pseudomonas fluorescens biofilms subjected to phage phiIBB-PF7A
Background: Pseudomonas fluorescens is an important food spoilage organism, usually found in the
form of biofilms. Bacterial biofilms are inherently resistant to a variety of antimicrobial agents,
therefore alternative methods to biofilm control, such as bacteriophages (phages) have been
suggested. Phage behavior on biofilms is still poorly investigated and needs further understanding.
Here we describe the application of phage ϕIBB-PF7, a newly isolated phage, to control P.
fluorescens biofilms. The biofilms were formed under static or dynamic conditions and with or
without renewal of medium.
Results: Conditions for biofilm formation influenced the feature of the biofilm and the morphology
of P. fluorescens. Biomass removal due to phage activity varied between 63 and 91% depending on
the biofilm age and the conditions under which the biofilm had been formed and phages applied.
Removal of the biofilm by phage treatment was faster in younger biofilms, but the same number of
surviving cells was detected in all tested biofilms, after only 4 h of treatment, even in older biofilms.
Under static conditions, a 3 log higher number of phage progeny remained either inside the biofilm
matrix or attached to the substratum surface than under dynamic conditions, pointing to the
importance of experimental conditions for the efficacy of phage entrapment into the biofilm.
Conclusion: Phage ϕIBB-PF7A is highly efficient in removing P. fluorescens biofilms within a short
time interval. The conditions of biofilm formation and applied during phage infection are critical for
the efficacy of the sanitation process. The integration of phages into the biofilm matrix and their
entrapment to the surface may be further beneficial factors when phage treatment is considered
alone or in addition to chemical biocides in industrial environments where P. fluorescens causes
serious spoilage.Fundação para a Ciência e a Tecnologia (FCT

Statistical Optimization of Xanthan Gum Production and Influence of Airflow Rates in Lab-scale Fermentor
The present study was undertaken to investigate and optimize the possibility of xanthan gum production by Xanthomonas campestris PTCC1473 in 500ml shake flasks on the second grade date palm. Using an experimental response surface methodology (RSM) coupled with a central composite design (CCD), three major independent variables (nitrogen source, phosphor source and agitation rate) were evaluated for their individual and interactive effects on biomass and xanthan gum production in submerged fermentation. The optimum conditions selected for gum production were 3.15 g.l-1 for nitrogen source, 5.03 g.l-1 for phosphor source, and 394.8 rpm for agitation rate. Reconfirmation test was conducted, and the experimental value obtained for xanthan production under optimum conditions was about 6.72±0.26 g.l-1, which was close to 6.51 g.l-1 as predicted by the model. A higher yield of biomass production was obtained at 13.74 g.l-1 for nitrogen source, 4.66 g.l-1 for phosphor source, and 387.42 rpm for agitation rate. In the next stage, scale-up from the shake flasks to the 1-L batch fermentors was carried. By using the optimum conditions for xanthan gum, the biomass and xanthan gum concentrations after 72h in three levels of air flow rate (0.5, 1 and 1.5 vvm) were obtained as 3.98, 5.31 and 6.04 g.l-1,and 11.32, 15.16 and 16.84 g.l-1, respectively. Overall, the second grade date palm seemed to exhibit promising properties that can open new pathways for the production of efficient and cost-effective xanthan gum
