Background:
Members of the anaerobic thermophilic bacterial genus Caldicellulosiruptor are emerging candidates for consolidated bioprocessing (CBP) because they are capable of efficiently growing on biomass without conventional pretreatment. C. bescii produces primarily lactate, acetate and hydrogen as fermentation products, and while some Caldicellulosiruptor strains produce small amounts of ethanol C. bescii does not, making it an attractive background to examine the effects of metabolic engineering. The recent development of methods for genetic manipulation has set the stage for rational engineering of this genus for improved biofuel production. Here, we report the first targeted gene deletion, the gene encoding lactate dehydrogenase (ldh), for metabolic engineering of a member of this genus.
Results:
A deletion of the C. bescii L-lactate dehydrogenase gene (ldh) was constructed on a non-replicating plasmid and introduced into the C. bescii chromosome by marker replacement. The resulting strain failed to produce detectable levels of lactate from cellobiose and maltose, instead increasing production of acetate and H2 by 21-34% relative to the wild type and ?pyrFA parent strains. The same phenotype was observed on a real-world substrate – switchgrass (Panicum virgatum). Furthermore, the ldh deletion strain grew to a higher maximum optical density than the wild type on maltose and cellobiose, consistent with the prediction that the mutant would gain additional ATP with increased acetate production.
Conclusions:
Deletion of ldh in C. bescii is the first use of recently developed genetic methods for metabolic engineering of these bacteria. This deletion resulted in a redirection of electron flow from production of lactate to acetate and hydrogen. New capabilities in metabolic engineering combined with intrinsic utilization of lignocellulosic materials position these organisms to provide a new paradigm for consolidated bioprocessing of fuels and other products from biomass.Source:

Home pregnancy tests have been practiced for long by women and is quite trusted way of confirming your doubts when it comes to conceiving. Here are certain signs that can tell you that you are probably pregnant.

If you have missed your period or you are having an abnormal or unusual period may be you are pregnant. If you have got frequent urinating tendencies or you throw up (vomit) again and again it is possible that you are pregnant. Generally women tend to lose their control over bladder when pregnant; it is very hard to control excretion of urine. Morning sickness or nausea is a tendency that is observed in pregnant women. They cannot resist throwing up again and again during the second and third months of pregnancy. Enlargement or soreness in breast is also indicates that possibly you are pregnant. Breast starts to grow big and become painful. If your breast is releasing colostrums, uterus is enlarged or you are getting a lot of stretch marks there is a possibility that you may be pregnant. In case you have frequent strange cravings like you have never had in past may be a n indication that you are pregnant.

However, these are not confirmed signs of pregnancy. Some of these symptoms when experienced together increase the probability of one’s pregnancy. You should immediately rush for a pregnancy test if you are even a little doubtful. This will clarify your doubts as it is a reliable way to test your pregnancy by yourself. You can also trace the pregnancy by an ultrasound test but home pregnancy strip test is more handy, cheap and reliable.

In case you are planning to conceive these are some symptoms that might be pointing towards your positive result on a pregnancy strip. Be happy you are experiencing such phenomenon and consult a doctor as soon as possible. Apart from all this reflect on your inner sight you can feel it when you are pregnant and the tests suggested above are just a primary confirmation.

In case you do not want to bear there are ways to get out of the web. Contraceptive pills are available in the market which can be a help in forbidding any pregnancy. There are pills that you can take within 72 hours after having unprotected sex to prevent pregnancy but its intake again and again can cause side effects. If you detect a positive on the pregnancy strip, you will have to abort it whether it is by an abortion pill or by any other method.
