“…Source of lipase occurs widely in nature, but only microbial lipases are commercially significant. Compared to plants and animals, microorganisms have been found to produce high yields of lipases within a short period of time (Mendes et al 2010). Microbial lipases are high in demand due to their specificity of reaction, less energy consumption, hydrolytic and synthetic activities, high yield and ease of genetic manipulation (Kumar et al 2012).…”

To isolate and characterize lipase producing bacteria from lipid-rich environment and screen the best lipolytic indigenous bacteria a study was made. For the isolation of bacteria, oil based wastewater and soil were collected from ten different sampling sites.Four different media were used for study the aerobic heterotrophic bacterial count. The highest bacterial count (1.56 × 10 7 cfu/gm) was observed in dairy farm soil and lowest (8.3 × 10 2 cfu/ml) in the Buriganga river water. The highest percentage (94.51) of lipase producing bacteria was found in edible oil mill soil and lowest (23.44) in the Buriganga river water. Among the total isolates 30 showed better lipase activity. Potential ten lipase producers were taken for molecular identification. Among them, nine genera were matched with their conventional identification but conventionally identified Acetobacter liquifaciens was found to be as Stenotrophomonas maltophilia. The enzyme produced by the isolated bacteria could be used for the treatment of lipid-rich wastewater.

“…Lipases also assist the regular performance of anaerobic digesters . By enzymatic treatment of fats in wastewater treatment plants, up to 90% scum containing mainly triglycerides can be hydrolyzed which can be further enhanced by immobilizing lipase synthesizing bacteria . Some wastewater may be highly treated and reused as reclaimed water.…”

Lipases are the industrially important biocatalysts, which are envisioned to have tremendous applications in the manufacture of a wide range of products. Their unique properties such as better stability, selectivity and substrate specificity position them as the most expansively used industrial enzymes. The research on production and applications of lipases is ever growing and there exists a need to have a latest review on the research findings of lipases. The present review aims at giving the latest and broadest overall picture of research and development on lipases by including the current studies and progressions not only in the diverse industrial application fields of lipases, but also with regard to its structure, classification and sources. Also, a special emphasis has been made on the aspects such as process optimization, modeling, and design that are very critical for further scale-up and industrial implementation. The detailed tabulations provided in each section, which are prepared by the exhaustive review of current literature covering the various aspects of lipase including its production and applications along with example case studies, will serve as the comprehensive source of current advancements in lipase research. This review will be very useful for the researchers from both industry as well as academia in promoting lipolysis as the most promising approaches to intensified, greener and sustainable processes. © 2017 American Institute of Chemical Engineers Biotechnol.

“…The effluent was biodegraded at 35 • C/100 rpm for 30 d, with a removal of COD obtained 2.3 to 2.9 times greater than that obtained with the raw effluent without enzymatic pretreatment. Mendes et al [117] investigated effluents from dairy industries, rich in lipids, partially hydrolyzed with a commercial porcine pancreatic lipase (Nuclear, São Paulo, Brazil, 1.77 U/mg) and obtained better results when the hydrolysis and degradation were carried out simultaneously using a low enzyme concentration (0.05% w/v).…”

Abstract:The establishment of a bioeconomy era requires not only a change of production pattern, but also a deep modernization of the production processes through the implementation of novel methodologies in current industrial units, where waste materials and byproducts can be utilized as starting materials in the production of commodities such as biofuels and other high added value chemicals. The utilization of renewable raw resources and residues from the agro-industries, and their exploitation through various uses and applications through technologies, particularly solid-state fermentation (SSF), are the main focus of this review. The advocacy for biocatalysis in green chemistry and the environmental benefits of bioproduction are very clear, although this kind of industrial process is still an exception and not the rule. Potential and industrial products, such as biocatalysts, animal feed, fermentation medium, biofuels (biodiesel, lignocelulose ethanol, CH 4 , and H 2 ), pharmaceuticals and chemicals are dealt with in this paper. The focus is the utilization of renewable resources and the important role of enzymatic process to support a sustainable green chemical industry.
