1. BEHAVIOR OF THERMALLY MODIFIED WOOD TO BIODETERIORATION BY XYLOPHAGE FUNGI
ABSTRACT Thermally modified wood undergoes chemical, physical, and mechanical modifications, resulting in changes in resistance to wood biodegrading agents. The objective of this study was to evaluate the resistance to biodeterioration of thermally modified wood by the industrial process VAP HolzSysteme® of Eucalyptus grandis, Pinus taeda and Tectona grandi

2. Analysis of biodeterioration wood estate: use different techniques to obtain images
ABSTRACT This study was based on the current status of locomotive turntable of Provincial Railway Station in La Plata. It was inaugurated in 1910 and it was declared as architectural heritage in 2006. The locomotive turntable is 200 meters from this station and it is a structure that consists in wooden slats of Schinopsis sp. into metal framework. Currently,

3. Efecto inhibidor del dióxido de germanio sobre el biofouling del puerto de Mar del Plata
ABSTRACT Marine biofouling on any new material immersed in seawater can lead to extra costs due to increased maintenance, or/and even mechanical wear, and/or biodeterioration that require costly antifouling measures. Fouling organisms growing on immersed manmade surfaces affect hulls, piers, buoys, aquaculture and pipes mainly. Following adsorption of a cond

4. Tannic extract potential as natural wood preservative of Acacia mearnsii
ABSTRACT High toxicity of the preservatives most frequently used in wood treatment and the resulting risks of handling pose a threat to small producers and to the environment. In an attempt to mitigate these problems, the present study was conducted with the objective of evaluating the preservative effect of tannic extract on biodeterioration of Acacia mearn

5. Biodegradation of films of low density polyethylene (LDPE), poly(hydroxibutyrate-co-valerate) (PHBV), and LDPE/PHBV (70/30) blend with Paecilomyces variotii
The increased consumption of plastics in the world has been a subject of great concern and special attention by the scientific community. The aim is to promote development of materials that are biodegradable in a shorter time upon disposal in the environment. The most used synthetic plastics are difficult to biodegrade because they are made of long hydrocarb

6. Microbiologically induced deterioration of concrete: a review
Microbiologically induced deterioration (MID) causes corrosion of concrete by producing acids (including organic and inorganic acids) that degrade concrete components and thus compromise the integrity of sewer pipelines and other structures, creating significant problems worldwide. Understanding of the fundamental corrosion process and the causal agents will

7. Biodeterioration studies of thermoplastics in nature using indigenous bacterial consortium
Thermoplastics, poly vinyl chloride and low-density polyethylene were treated in the presence of indigenously developed bacterial consortium in laboratory and natural conditions. The consortium was developed using four bacteria, selected on the basis of utilization of PVC as primary carbon source, namely P. otitidis, B. aerius, B. cereus and A. pedis isolate

8. Evaluation of the effect of dry-film biocides on paint film preservation using neural networks
Biocides play an important role in the preservation of a variety of products susceptible to microbiological growth such as paint, a material that can undergo microbial deterioration both in storing (inside the can) and after the application on a surface. In this work, artificial neural networks were used to predict the level of fungal growth on surfaces pain

9. Biodeterioração de misturas de diesel e biodiesel e seu controle com biocidas / Biodeterioration of diesel and biodiesel blends and its control with biocide
Durante o armazenamento, as vantagens do biodiesel tais como a biodegradabilidade, a afinidade pela água e a ausência de aromáticos, podem tornar o combustível ainda mais suscetível a contaminação microbiana, comprometendo a qualidade final do produto. Neste sentido, avaliou-se a suscetibilidade a biodeterioração de misturas de diesel com 5, 10 e 20

10. Caracterização bioquímica e molecular de isolados microbianos presentes em solo contaminado por petróleo
The bioremediation processes are becoming increasingly sought strategies related to soil contamination by oil. To achieve this goal, one good alternative is the isolation of indigenous microorganisms from the impacted region, to study and to know the native species, their diversity and metabolism, and then use the best microbial specie as inoculum on bioreme

12. Biodeterioration of coastal concrete structures by Macro algae - Chaetomorpha antennina
Puducherry is a coastal region in India where the growth of Chaetomorpha antennina is very abundant on all marine concrete structures. Though the detrimental effect of this Macro algaeChaetomorpha antennina is secondary, its effect has to be ascertained. To know its effect, M20 grade concrete cubes were cast and kept in the coastal area where there is abunda
