Consolidated Bioprocessing: QTEROS

QTEROS is Marlborough, Massachusetts, United States based cellulosic ethanol producer company. It is applying ‘Consolidated bioprocessing’ to produce ethanol through its proprietary ‘biomass to cellulosic ethanol’ conversion process which is based on its patented ‘Q Microbe®’. The company is in its early-stage.


QTEROS is focusing on biomass feedstock such as wet distillers grains and sugar cane bagasse. Although a broad range of biomass such as agricultural residues including corn stover, corncob, and wheat straw and energy crops have been found suitable for QTEROS’s consolidated bioprocessing.

Consolidated Bioprocessing: Q Microbes

Consolidated bioprocessing aims to combine the various steps of ethanol production from lignocelluloses into one step. It attempts the production of lignocellulose hydrolyzing enzymes, breakdown of the complex carbohydrates of the pretreated biomass into simple sugars (saccharification) and fermentation of released hexose and pentose sugars into ethanol in one pot as much as possible.

QTEROS uses its patented naturally occurring ‘Q Microbe®’ to do the biomass to ethanol conversion. The scientific name of the Q Microbe® is Clostridium phytofermentans. It was discovered in 1996 by microbiologist Dr. Susan Leschine and her lab assistant Tom Warnick of University of Massachusetts near the Quabbin Reservoir in Western Massachusetts. Q Microbe is able to express the enzymes required for the extraction of fermentable sugars from biomass and directly converting fermentable sugars such as cellulose, xylan, pectin, and starch to its primary byproduct ethanol.

The company is developing its “Q Microbe” as a licensable key technology for consolidated bioprocessing. Their research now focuses on identifying and optimizing the best biomass materials for Q Microbe and the enhancement of the strain through genetic engineering. They are attempting to pilot its technology to bring it to the market.

Karnataka to get $50 million dollars for biofuel

In India the Karnataka States’ Biofuel Development Programme  is set to get a boost in the form of  $50 million dollars from International Fund for Agriculture Development (IFAD). The loan can be utilized in various activities such as plantation of biofuel crops and production. Biofuel Development Board of Karnataka has been active in promoting biofuels and  has established biofuel information and demonstration centres with about 100 l per day capacity in each district. These centres are being scaled up to 150-200 l capacity. The Board also owns a 500 litre biodiesel production plant at Hatti Gold Mines. The loan conditions include 1% interest with a 50-year repayment period.

China’s first commercial flight powered with biofuel was successfully completed

China's first commercial flight powered with biofuel was successfully completed between Shanghai and Beijing. The privately owned Hainan Airlines flight used biofuel made up from used cooking oil collected from the restaurants. The biofuel was supplied by China National Aviation fuel company and energy giant Sinopec. It was a Boeing 737 plane which used 50% biofuel blended in conventional jet fuel and carried more than 100 passengers to their destination.

India achieved only 1.4% ethanol blending this fiscal year

Problems between sugar mill owners and oil marketing companies have resulted in only 1.4% ethanol blending through february this fiscal year which is way less than the blending target of 5% and lesser than the last year's achieved blending level of 2%.The National Policy on Biofuels of India identifies the sugar cane molasses as the feedstock suitable under Indian conditions for ethanol production for blending purpose and that makes the sugarcane mills as the biggest suppliers of bioethanol. The high state-level levies on the biofuel and the requirement of obtaining permits from authorities have been sited as the major impediments for producing bioethanol by Sugar Mills. The government has set the selling price of ethanol for sugar mills @  Rs. 48.50/litre  if the depo of the oil marketing company is within 100 km from distillery and  @49.50/ litre  if the depo is beyond 300 km. The producers claim that the long distance transportation also reduces their margin. India needs approximately 115 crore litres of ethanol to meet the 5% target. Read more at
