The world’s population is growing constantly. According to the UN, by 2050 the world will have to meet the nutritional needs of 9 billion people. Corn, soybeans, wheat and rice are important staples of their diet. Meeting this growing need will require increasing agricultural productivity from crop land already in production. One way to do this is to minimize the impact of environmental factors such as drought that can lead to poor crop growth or even failed harvests.
While plants can be selected to tolerate adverse environmental conditions through breeding, it could take decades to achieve this goal. Plant biotechnology offers better opportunities for speeding up this process and more importantly, making it more target focused. By introducing selected gene sequences, scientists are trying to improve crop traits. Researchers have successfully inserted such a gene, called cspB, originally from the Bacillus subtilis bacterium, into the genome of corn plants. This gene reduces the impact of drought stress on yields. In collaboration with Monsanto, BASF scientists are using proprietary technology to study the cspB-containing corn plants. When crops grow healthier with less water, it’s because at BASF, we create chemistry.

Gram stain of the Bacillus subtilis bacteria. It is a gram positive rod, if you look closely you can see what appear to be bubbles in the cell. That is the endospore. The endospore is nearly impossible to kill and allows the bacteria to survive in harsh conditions. #bacillus #subtilis #bacteria #grampositive #gramstain #endospore #science #micro #microlab #microbiology #pathogenicmicro #microscope #microscopy #survival #instagood #latergram #rods (at Quinnipiac University)

Me jamming out some ideas on my bass.

Testing the #hemolytic ability of Bacillus subtilis. For some reason, our lab strain was producing a weak beta, which is silly because Bacillus subtilis is an environmental bacteria with no reason to lyse red blood cells. #micro #microlab #microbiology #science #life #instagood #latergram #laboratory #strain #bacillus #subtilis #bacteria #bacterialcolony #bloodagarplate #BAP (at Quinnipiac University)

Going Loopy

To successfully survive in an environment, bacteria have to overcome many a challenge – for example migrating to food sources, which could be at some distance from each other. To do this, the bacterium Bacillus subtilis – that lives in the soil and is used in producing antibiotics – not only uses its whip-like flagellum to propel it in a kind of swimming motion, it can also ‘slide’. In doing so, B.subtilis form multicellular structures, allowing many to move forward and spread in bundles. These chains of cells, called van Gogh bundles, are strongly aligned (top panel) to form threadlike loops at the edge of the bacterial colony. As the loops grow they push away and the whole colony moves from the centre, forming a petal shape at the colony edge (bottom panel). Insight into this type of systematic cell organisation will help to understand how other bacterial species function.

Trying to keep our setup small and simple. A single soft light source using diffusion meant hot spots on our model were reduced and shadows were kept soft. For curiosity this lighting worked a lot better than the dark moody lighting we had to start with.

The camera worked out easy to use for stop motion as it had an onion skinning mode so progression of shots was easier to judge and the older lenses subtily added to the mood, allowed us to get close up use shallow depth of field, something that also added to the whole curious theme.

I think I’m addicted to Bacillus subtilis-fermented soybeans with dashi, help. #natto #納豆

This test involves three things. Sulfur Indole and Motility. I never actually get an organism that is Indole positive. Makes me sad. This organism was negative for all three. #SIM #sulfur #indole #motility #bacteria #bacillus #subtilis #biochemicaltests #testtube #testing #science #healthscience #instagood #latergram #micro #microlab #microbiology #pathogenicmicro #lab #laboratory (at Quinnipiac University)

—  In English that translates to –
(“To those surrounding and the reader of this script, you have trespassed across a sacred ground moulded by the acts of our ancestors. To read is to violate our spiritual struggles and bring torment to the many souls lost within offering. I plead to the gods to take pity, voicing only a subtle reminder to the choices you made this day.”)
