“…There were progressive reductions in residual total hydrocarbons, particularly in the amended soils. Degradation rates decreased during 12 months, because, the numbers of hydrocarbon utilizing micro-organisms have usually been found to be high in soil immediately and a few months after oil application (Molina-Barahona et al, 2004). Degradation rate under natural conditions (A 5 ), was 161 mg kg -1 day -1 in the first 3 months and drop to 72 mg kg -1 day -1 at 12 months (Table 3).…”

“…Naturally occurring micro-organisms may be able to biodegrade hydrocarbons and other organic compounds in unsaturated soil if the level of contaminations is low and does not produce toxicity for the active bacteria (Molina-Barahona et al, 2004). Biodegradation of petroleum hydrocarbons in soil can be limited by many factors, for example: type of micro-organisms, nutrients, pH, temperature, moisture, oxygen and soil properties.…”

Global emphasis on food security and soil health should consider rehabilitation of degraded lands, especially where oil contamination limits the use of such lands. Three legume plants (Gliricidia sepium, Leucaena leucocephala and Calapoconium caerulean) alone or along with 0.5% (w/w) (equivalent of 10 tons ha -1 ) poultry manure, were used to treat the soil, in which the oil residuals were monitored for three years. Results showed that significantly high levels of residual total petroleum hydrocarbon content (RTPHs) persisted in the non-amended soil after 36 months. At 3 months, 43% of RTPHs was removed by Gliricidia sepium and Leucaena luecocephala along with poultry manure. Net loss of RTPHs after 12 months was 69% for Gliricidia sepium and Leucaena luecocephala combined with poultry manure and only 38% for A 5 , explaining that, degradation of petroleum hydrocarbon by indigenous soil micro-organisms was very low. At 18 months when additional load of oil was applied, the degradation rate increased from 71.7 mg kg -1 day -1 to 142 mg kg day -1 within 6 months for all the legume plants along with poultry manure. This explained increased in number of hydrocarbon-degrading micro-organisms due to increase in oil load. The oil inhibited germination and yield of maize crop completely. Treatments with legume plant along with poultry manure significantly (p < 0.05) increased both germination and yield of maize crop. The effects of legume plants combined with poultry manure were the better treatment than legume or poultry manure alone in improving the soil properties for growth and performance of maize crop.

“…As preocupações ambientais, incipientes até a ocorrência da 2ª Guerra Mundial, demonstraram ser de vital importância na medida em que mais e mais acidentes ambientais passaram a ocorrer, estimulando a pesquisa de forma a reparar ou minimizar, nos processos produtivos, esses danos ambientais. Além disso, a pressão por parte dos governos e da opinião pública tem forçado essa postura ambientalmente correta das indústrias, estabelecendo leis que regulam o gerenciamento ambiental (MARTINS et al, 2003;MOLINA-BARAHONA et al, 2004;). No atual contexto mundial em que a preocupação com o meio ambiente vem crescendo abruptamente, o domínio de tecnologias limpas tornou-se essencial para qualquer país que deseja biorremediar suas contaminações sem a necessidade de agredir o meio ambiente.…”

RESUMOO progresso tecnológico aliado a um crescimento demográfico sem precedentes trouxe riscos de exploração excessiva dos recursos e destruições irreversíveis ao patrimônio natural. A política ambiental vinculada a uma política econômica, nos pressupostos do desenvolvimento sustentável, deve ser essencialmente estratégia de risco destinada a minimizar o conflito entre desenvolvimento econômico e sustentabilidade ecológica. O presente trabalho apresenta um mapeamento tecnológico dos processos de biorremediação dentro do contexto da biotecnologia sustentável por meio de indicadores de patentes, utilizando o software de busca e análise de dados Orbit.Palavras chave: Biorremediação. Biotecnologia Sustentável. Patente. Mapeamento Tecnológico. ABSTRACTTechnological progress combined with a population growth brought unprecedented risks of overexploitation of resources and irreversible destruction to the natural patrimony. Environmental policy linked to an economic policy, the assumptions of sustainable development should be essentially risk strategy designed to minimize conflict between economic development and ecological sustainability. This paper presents a technology mapping of bioremediation processes within the context of sustainable biotechnology through patent indicators, using the software search and analysis of Orbit database.
