“…According to Nunes et al [49] and Papanikolaou et al [50], among different vegetable oils, olive oil is considered as the best inducer of lipase production. The result, to some extent, also correlates with the findings by Lakshmi et al [51] that lipase production increases with relative increase of C18:n fatty acid esters in the respective vegetable oils, with olive oil having the highest percentage composition of C18:n fatty acid and coconut oil having the least [52]. Our results revealed olive oil as the highest lipase inducer and coconut oil as the lowest inducer of lipase production (Fig.…”

This study investigated the screening, production and optimization of an extracellular lipase from a fungus isolated from the contaminated soil of a palm oil processing shed. This was with a view to obtaining a strain that can secrete lipase with biochemical properties exploitable for biotechnological applications such as bioremediation of oil contaminated sites. Soil samples were collected from palm oil contaminated sites in Gbogan, Osun State, Nigeria (Latitude N 7°29.1481´ and Longitude E 4°20.7587´). The isolated fungal strains were screened on tributyrin agar for exogenous lipolytic activity. Molecular identification was carried out by amplifications of ITS-1, 5.8S and ITS-2 regions. The effects of incubation time, inducers, pH, temperature, carbon and nitrogen sources were varied for optimal lipase production using one factor at a time approach. Rhizopus oryzae ZAC3 (NCBI accession No: KX035094) was identified as the highest lipaseproducing strain. Maximum lipase production was observed on the fourth day, pH 5.0 and a temperature of 45 o C. Olive oil, xylose and yeast extract were the best inducer, carbon and nitrogen sources respectively for lipase production. There was a 2.02 fold increase in lipase production under these optimized conditions. In conclusion, Rhizopus oryzae ZAC3 lipase has properties exploitable for industrial and biotechnological applications.

“…Uma série de metodologias para obtenção de biodiesel encontra-se disponível na literatura [7][8][9][10][12][13][14][15][16][17][18][19] . Nelas são discutidas as variá-veis que influenciam a eficiência do processo, bem como a qualidade do produto formado, como por ex., a quantidade de material catalítico, a razão molar álcool/óleo vegetal, a intensidade da agitação mecânica, a pureza dos reagentes, o teor de ácidos graxos livres no material de partida e o tempo reacional.…”

“…Embora o conceito sobre biodiesel esteja sob discussão, este termo pode ser empregado para descrever ésteres de ácidos graxos de cadeia longa (monoésteres alquílicos) derivados de fontes renováveis, tais como óleos vegetais e gorduras animais 3,7,8 . O biodiesel surgiu como uma alternativa para a substituição ao óleo diesel, contribuindo para minimizar a dependência das importações do petróleo, como também para a redução da poluição ambiental, através da diminuição das emissões de gases poluentes.…”

“…Methanol is available as M85 (a mixture of 85 per cent methanol and 15 per cent unleaded petrol) or M100 to reduce the air pollution. While Methanol's advantages include lower emissions, higher performance and lower risk of flammability, the downside involves producing a high amount of formaldehyde in emissions [28,42,43]. Since most of the energy sources have advantages as well as disadvantages, hence hybrid system using more than one energy sources may be considered as the proper alternative to get optimal efficiency with least air pollution [44][45][46][47].…”

An explorative study to enable environmentally conscious manufacturing for an industrial gearbox manufacturing organization

-In recent years, environmentally conscious manufacturing (ECM) has become an important aspect and proactive approach for majority of the manufacturing organizations in India. The reason is that ECM not only helps to produce environment friendly, but also helps to make money by reducing cost or achieving competitive advantage. Industrial gearbox manufacturing organizations have significant environmental impacts as industrial gearbox manufacturing involves several steps which use valuable resources and pollute the environment. Hence, this paper presents an explorative environmental study of an Indian industrial gearbox manufacturing organization. The objective of the current paper is (i) to identify the environmental problems and environmentally conscious manufacturing indicators (ECMI), (ii) to find out the root causes of these problems and (iii) to solve the root causes based on the available stateof-the-art literature. This research work not only reviews the efficient environment friendly manufacturing techniques, but also helps the organization to become eco-efficient by producing environment friendly while making money. First ECMIs selected from literature review, are validated through process mapping. Then these indicators are prioritized using analytic hierarchy process (AHP) to find out the critical environmentally conscious manufacturing indicators (CECMI). The sources of CECMIs are identified using either data envelopment analysis (DEA) or direct observation of the available database. Finally, some possible solutions are also addressed in this paper.
