Abstract:
This paper evaluates the ability of secretome from two thermotolerant fungal strains (Aspergillus terreus 9DR and Achaetomium strumarium 10DR) for boosting the hydrolytic efficiency of benchmark cellulolytic preparation (Cellic CTec2). Further we report enhanced saccharification of different agro-residues under semi-aerobic when compared to aerobic conditions. The mass spectroscopic analysis of the hydrolysates indicates the role of auxiliary oxidative enzymes present in A. terreus and A. strumarium secretomes for enhancing the capability of the cellulolytic cocktails. The paper further demonstrate positive effect of using the cocktails for enhanced saccharification and subsequent fermentation to ethanol of acid pre-treated rice straw, corn residues and sugarcane bagasse at higher substrate loading rates (20% w/v). The paper also reports co-utilization of composite sugars derived from molasses and enzymatic hydrolysate obtained from agnostic lignocellulosics for efficient bioconversion to ethanol applicable for developing BOLT-ON technology.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
