Nisin is a bacteriocin produced by microbial fermentation of the well-known starter culture for dairy products, Lactococcus lactis. A major challenge in food safety and security prevention emergence unwanted microbes. Artificial preservatives added to prolong shelf life foods may have negative effects on consumer health. An alternative approach use bio-preservatives. However, cost production ni...

Karnataka state stands 3rd position in terms of sugar production and 4th cultivation sugarcane the India. In fact, there are presently around 64 working factories with annual crushing capacity 3.29 lakh MT/day, cogeneration 1500 MW/day, alcohol 2100 KLPD ethanol 1130 KLPD. year 2017-18, industry had crushed a total 347.5 MT cane produced 36.87 Lakh sugar. The is able to manufacture such huge qu...

Motor fuel grade ethanol (MFGE) is the fastest growing market for ethanol worldwide; and MFGE production dwarfs the combined total production of all other grades of ethanol. Fermentation ethanol, as fuel (and solvent), has experienced several cycles of growth and decline since the early 1800s. By 1860, production had reached more than 90 million gallons per year. In 1861 Congress imposed a tax ...

Exhaustibility tests were carried out by concentrating molasses to 4 000 poise (determined a t 40°C), adding refined sugar, crystallising at 40°C for 48 hours and carrying out on the separated molasses a series of analyses which included sugars by gas-liquid chromatography (GLC) as well as Lane and Eynon methods. Regression analysis of the results showed that purity of the exhausted molasses wa...

Molasses is one of the most important by-products in sugar industry, which contains a large amount of sucrose. The routine way to separate the sucrose from molasses is using steffen method. Whereas this method is very usual in sugar factories, the aim of this research is optimization of this method. Mentioned optimization depends to three factors of reactor alkality, reactor temperature and dil...

In a period of 1 year, the volumetric ratio of wastewater from a cane molasses-based bio-ethanol distillery plant (CMBP) and a cane sugar mill (CSM) was monitored and shown to be 1:2. In order to evaluate the validity of mixing the two wastewaters, their biodegradability and methanogenic activity (MA) were measured under a fixed temperature of 35°C and fixed FM ratio of 0.5 (i.e., 2 g COD/l for...

A survey has been carried out on the composition of final molasses from South African sugar factories. Regional and seasonal trends in various parameters have been noted, and the degree of exhaustion of the molasses has been commented upon. Included in the survey are data on the nonsucrose constituents of molasses, and the inorganic ash components. Comparisons are made with a similar survey con...

The objective of this study was to investigate the effects of adding different levels of molasses (1-5%) on the silage quality, in vitro methane production and in vitro organic matter digestibility (IVOMD) of pistachio (Pistachio vera) by-product and wheat straw mixture silages. For this purpose, silages were prepared with pistachio by-product (85%) and wheat straw (15%) without molasses (contr...
