BIOCIDES FOR DISTILLERY

(Booster for fermentation-S-CIDE-M(s).)


INTRODUCTION

1.  Biocides are chemical compounds. It is general name for any substance that kills or inhibits the growth o microorganisms such as bacteria, molds, slimes, fungi, etc. Many of them are also toxic to humans. Biocidal chemicals include chlorinated hydrocarbons, organometellics, and halogen releasing compounds, metallic salts, organic sulphur compounds, quaternary ammonium compound, and phenolics. It is 100 % eco. Friendly and safe for use.


2. How and why do Microorganisms Make Alcohol?

Energy conversion by living cell is the fundamental property. Living cells produce useful energy ATP, which is regarded as the cells energy currency.

Yeast has the property to maintain the stock of ATP, which is possible due to the consumption of sugars like glucose, and fructose. Sucrose is the main component of sugar-cane juice which consists of the glucose molecule attach to the one molecule of fructose. The first step of yeast’s activity is to break apart the glucose and fructose units which enter the energy metabolization machinery to provide energy.

If yeast grown in oxygenated medium, the sugar will be broken down step by step, into smaller and smaller molecules and at the end carbon dioxide is liberated. However, if there is little oxygen or no oxygen available to the yeast the series of chemical breakdown processes cannot be completed and the sugar is broken down into ethanol-a fuel alcohol.


C6H12O6 = 2C2H5OH + 2CO2

DGO = - 56 Cal


Glucose is splited up into two molecules of pyruvic acid via the reactions of glycosis. Alcoholic fermentation and aerobic degradation follow the same reaction frequencies up to this point. In fermentation pyruvic acid is degraded enzymetically to alcohol and carbon dioxide.


3. Mode of Action

Bacterial contamination of molasses in the fermentation process leads to many critical problems during alcohol production. Reduction of fermentation efficiency low alcohol yield and increased volatile acidity are the basic problems associated with bacterial contamination.

S-CIDE-M(s) is a specially developed biocide which effectively controls the losses during fermentation process by checking the bacterial contamination.

It is a blend of two types of yeast friendly biocides which acts on the principle of bacteriostatic agent. Its broad spectrum action inhibits the micro-organisms effectively thereby minimizing process disruptions in terms of yield and efficiencies.


4. BIOCIDE-M FOR DISTILLERY FERMENTATION PROCESS

Bacterial contamination of molasses in the fermentation process leads to many critical problem during alcohol production. Increased contamination loads coming from molasses get aggravated during fermentation stage due to more dilution with water. Reduction of fermentation efficiency, low alcohol yield and increased volatile acidity are the basic problems associated with the bacterial contamination. Presence of bacteria suppresses the yeast growth and in no time it affects the yeast population. Hence it is necessary to control bacterial contamination in the fermentation process for better yields and better efficiencies.





 Enzymes for Distilleries 

S-Zyme-M(s) is an enzyme , yeast nutrients especially manufactured for alcohol distilleries to increase the distillery’s efficiency and profitability. S-Zyme-M(s) is completely eco-friendly and used to increase the alcohol yield during fermentation process in the distillery.


Properties

  • S-Zyme-M(s) supplements the yeast nutrients which improves the fermentability of molasses
  • It help to prevent the contamination and  converts petosanase, starch in molasses in to simple sugars, which in turn utilized by the yeast thus increases the alcohol yield
  • Increase in alcohol yield by 0.5-1 %
  • Increase in profitability of the plant
  • Consistency in the results as compare with the existing suppliers.

Enzymes for Textiles 

Drawing on our substantial experience and strong competencies in R&D and customer solutions, we continue to deliver highly effective products while offering our partners unmatched support in the use of enzymes for wet-processing textiles. Our solutions can decrease dependence on chemicals, lower consumption of energy and water, and bring down costs – all while maintaining superior product quality. 

The use of enzymes in textile industry is one of the most rapidly growing field in industrial enzymology. The enzymes used in the textile field are amylases, catalase, and laccase which are used to removing the starch, degrading excess hydrogen peroxide, bleaching textiles and degrading lignin. The use of enzymes in the textile chemical processing is rapidly gaining globally recognition because of their non-toxic and eco-friendly characteristics with the increasingly important requirements for textile manufactures to reduce pollution in textile production. The application of cellulases for denim finishing and lactases for decolourization of textile effluents and textile bleaching are the most recent commercial advances. The use of enzyme technology is attractive because enzymes are highly specific and efficient, and work under mild conditions. Furthermore, the use of enzymes results in reduced process times, energy and water savings, improved product quality and potential process integration. The aim is to provide the textile technologist with an understanding of enzymes and their use with textile materials.

Properties of enzymes used in textiles :

  • An enzyme accelerates the rate of particular reaction by lowering the activation energy of reaction.
  • The enzyme remains intact at the end of reaction by acting as catalyst.
  • Each enzyme have optimum temperature and optimum pH i.e. activity of enzyme at that pH and temperature is on the peak 
  • For most of the enzyme activity degrades on the both sides of optimum condition.
  • Enzymes can be used as best alternative to toxic, hazardous, pollution making chemicals
  • Also some pollutant chemicals are even carcinogenic. When we use enzymes there is no pollution
  • Most enzymes have high degree of specificity and will catalyze the reaction with one or few substrates
  • One particular enzyme will only catalyze a specific type of reaction. Enzymes used in desizing do not affect cellulose hence there is no loss of strength of cotton
  • Enzymes are easy to control because their activity depends upon optimum condition
  • At the end of reaction in which enzymes used we can simply drain the remaining solution because enzymes are biodegradable and do not produce toxic waste on degradation hence there is no pollution.

Enzymes are available for the following processes 
  1.   Textile desizing enzyme.

  2.  Bio-polishing fabric/garments( acidic)

  3. Bio-wash neutral

  4.  Bio-stone washing fabric/garments (acidic) Fading



 Enzymes for Paper and Pulp Industries




The pulp and paper industry is challenged by manufacturing processes that have traditionally required large amounts of water, energy, and chemicals. Ore Enzyme's solutions save resources and costs while improving the quality, performance, and appearance.Enzymes augment many of the processes at the mills with less effort and better results. That means savings in electricity, water, and harsh chemicals, thereby reducing environmental impacts and providing cost savings for pulp and paper mills. 






Paper and Pulp Enzymes Properties-

• Are proteins that catalyze chemical reactions
• Biological cells need enzymes to perform needed functions
• The starting molecules that enzymes process are called substrates and these are converted to products
• Are extremely selective for specific substrates
• Activity affected by inhibitors, pH, temperature, concentration of substrate
• Commercial enzyme products are typically mixtures of different enzymes, the enzymes often complement the activity of one another.

Enzyme Applications in Pulp and Paper-

• Treat starches for paper applications
• Enhanced bleaching
• Treatment for pitch
• Enhanced deinking 
• Treatment for stickies in paper recycling
• Removal of fines
• Reduce refining energy
• Cleans white water systems
• Improve softness in tissue
• Clean outs
