Abstract

In-house production of cellulases from filamentous fungi is widely used, but their hydrolytic efficiency compared to commercial enzymes is limited. We studied the effect of supplementing in-house cellulases produced by Trichoderma reesei, RUT C30 and a novel strain, Aspergillus saccharolyticus with different types of commercial enzymes for the efficient hydrolysis of wet exploded loblolly pine. Cellic®Ctec 2, Cellic®Htec2 and Novozym 188 were used as the commercial base enzymes for supplementing the in-house produced enzymes. Compared to non- supplemented in-house enzymes preparation, commercial enzymes (Cellic®Ctec2) added in the same amount as FPU and CBU, resulted in 68% higher glucose yield using wet exploded loblolly pine (WELP) at a 20% DM concetration. The highest saccharifcation yield was achieved by supplementation of the in-house produced cellulases with Cellic®Htec2 compared to Cellic®Ctec2 and Novozym 188. Optimal glucose, xylose and mannose yields, 85%, 92% and 86%, respectively were achieved by using in-house enzymes (15 FPU/g cellulose) supplemented with commercial hemicellulase (7.5 FPU/g cellulose). These results showed that supplementing in-house enzymes with commercial enzymes can be advantageous and work for lowering the overall cost of enzymes in a biorefinery.

Highlights

  • Breast cancer is the most common of all cancers and is the leading cause of cancer deaths in women worldwide, accounting for >1.6% of deaths and case fatality rates are highest in lowresource countries

  • The activity of Punica granatum was good against cancer cell line .from this we concluded that pomegranate fruit peel extract (PPE) shows a better cancerous activity against the cancer as compare to PSE

  • The development and refinement of risk prediction models provide an epidemiologic basis for counseling women with a family history that does not appear related to a dominant susceptibility gene

Summary

Introduction

Breast cancer is the most common of all cancers and is the leading cause of cancer deaths in women worldwide, accounting for >1.6% of deaths and case fatality rates are highest in lowresource countries (www.tmc.gov.in). Conclusion: The activity of Punica granatum was good against cancer cell line .from this we concluded that PPE shows a better cancerous activity against the cancer as compare to PSE. On Thursday, January 2, 1997, Dr Herbert Soule, the scientist who developed the MCF-7 breast cancer cell line, died.
