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.

“…One of the possible methods is to develop efficient biological control agents that can control larvae and adults at the breeding sites (Seneshaw and Mulugeta, 2002). Biological control agents, which include naturally occurring microbial biocontrol agents, have great potential in controlling pest populations with little or no detrimental effects on human health and the environment (Khan et al, 2012). Among them, the entomopathogenic fungi (EPF) are most preferred because of ease of production and application, mode of action that does not need ingestion of the entomopathogen by the target pest (Butt, 2002;Wang and St. Leger, 2007;Thomas and Read, 2007).…”

Sorghum chafer, Pachnoda interrupta (Olivier) is a damaging pest of sorghum, other cereals and horticultural crops in Africa which results in complete crop loss. Currently, the management strategies rely heavily on chemical pesticides, which do not provide effective control. There is evidence showing that microbial biocontrol agents have the potential to control P. interrupta. In this study, the entomopathogenic fungi isolated from soils and insects in Ethiopia were identified using morphological and cultural characteristics. These were then evaluated for viability and virulence against Galleria mellonella (Fabricius) (Lepidoptera, Pyralidae) larvae and P. interrupta adults. Firstly, 116 Metarhizium spp. and Beauveria spp. were considered. The isolates were evaluated based on high viability as measured by percentage germination on SDA media. Only 56 isolates had greater than 70% viability. Secondly, these were further evaluated using conidial suspensions applied to G. mellonella larvae at a concentration of 1×10 8 conidia/ml. Four Beauveria spp. and three Metarhizium spp. isolates which caused over 60% mortality were selected for final virulence assay against adults of P. interrupta. The selected isolates were further confirmed by PCR amplification of ITS4 and ITS5 gene regions and chi1 and chi4 primers. Finally, the seven isolates were evaluated for virulence against P. interrupta at a dose of 1 mg dry conidia/10 beetles under laboratory condition. Mortality of P. interrupta ranged from 14% for isolate 9604 to 82% for isolate PPRC51. Dose-response tests showed that the LD 50 of PPRC2 (0.62 mg/10 beetles) and PPRC51 (0.55 mg/10 beetles) isolates were not significantly different from each other. The results demonstrated the high potential of the two isolates (PPRC51 and PPRC2) as microbial biocontrol agents. However, field evaluation of the isolates should be performed for their development into a mycopesticide against P. interrupta.

This book series provides complete, comprehensive and broad subject based reviews about existing biodiversity of different habitats and conservation strategies in the framework of different technologies, ecosystem diversity, and genetic diversity. The ways by which these resources are used with sustainable management and replenishment are also dealt with. The topics of interest include but are not restricted only to sustainable development of various ecosystems and conservation of hotspots, traditional methods and role of local people, threatened and endangered species, global climate change and effect on biodiversity, invasive species, impact of various activities on biodiversity, biodiversity conservation in sustaining livelihoods and reducing poverty, and technologies available and required. The books in this series will be useful to botanists, environmentalists, marine biologists, policy makers, conservationists, and NGOs working for environment protection.More information about this series at
