    Bacteria can create a beautiful art that can only be seen with the use of a microscope.

    When we think about bacteria, we often think that they are the micro organism that causes diseases. Example of a disease causing bacteria is the Streptococcus which causes a strep throat. There are many species of bacteria, some of them are bad but some of them are good. They can be found in the highest mountain and they can be found in the deepest of the sea. But bacteria play an important role in our ecosystem as our ecosystem depends on their activities. Their heavy labor is the cause of a complete cycle of nutrients like carbon, nitrogen and sulfur which we need.

    Bacteria are single cell that are complex yet fascinating. They can live in the highest boiling point and they can also live in the freezing point and they are the earliest form of life that appeared on earth. The shape of bacteria have different kinds, they have stick like or rod like shape, round shape and the spiral shape. These bacteria live in clusters so they can form into pair, chains, squares or other kinds of groupings. Bacteria's are so small that you can only see them in a microscope.

    Now, how can you create an art from the bacteria? You might think. Bacteria have natural colors. Some of them may contain pigments like the chlorophylls which has a natural color of green, yellow, orange and brown. If the bacteria has turned into colonies of millions they turn into pink, yellowish and sometimes white.

    In Bacteria Art, a scientist would grow the different kinds of bacteria into a Petri dish. A Petri dish is a cylindrical container with a lid where biologists use to study cells. This is how scientist studies the bacteria's in order for them to create new antibiotics. The bacteria then create colonies and therefore make a very unique pattern that will very much look like an art with different colors. This is now what they call a Bacteria Art.

    细菌能创造出美丽的只能用显微镜才能看得到的艺术品。

    一想到细菌,我们通常会认为细菌是能够致病的微生物,例如,致病的链锁球菌能引起链球菌咽炎。细菌种类多样,有些对人类有害,有些却对人类有益;山之最高处,海之最深处,均能找到它们的踪迹。不过,因为我们人类所处的生态系统离不开细菌的活动,因而细菌扮演着重要的角色。正是由于他们强大的活动力,我们人体需要的养份如碳、氮、硫等元素才能周而复始地循环。

    细菌是复杂而又迷人的单细胞生物,在最高沸点和冰点环境中均能存活。此外,细菌还是地球上最早出现的生命形式,他们形状多样,如棒状、杆状、圆形状、螺旋状等。这些细菌群生在一起,从而成双、成链、成方,或者形成其他族群。细菌体积极小,只有通过显微镜才能看得见。

    那么,我们如何利用细菌创造艺术品呢?您不妨动动脑筋。细菌色彩天然,有些可含有像叶绿素般的色素,拥有绿、黄、橙、褐等天然颜色。如果细菌数以百万计地组成多种菌落,就会呈现出粉红、蛋黄等颜色,有时候还会呈现出白色。

    在细菌艺术创作中,科学家可能会将不同种类的细菌培育在皮氏培养皿中。皮氏培养皿是一种有盖的圆柱型容器,生物学家利用这个盖子来研究细胞。科学家就是这样研究细菌的特性,以便它们产生新的抗生素。接着,细菌形成菌落,从而构成一个非常独特的图案,看上去就像一件拥有不同颜色的艺术品,也就是现在科学家所称的细菌艺术品。
