    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.

    細(xì)菌能創(chuàng)造出美麗的只能用顯微鏡才能看得到的藝術(shù)品。

    一想到細(xì)菌,我們通常會(huì)認(rèn)為細(xì)菌是能夠致病的微生物,例如,致病的鏈鎖球菌能引起鏈球菌咽炎。細(xì)菌種類多樣,有些對人類有害,有些卻對人類有益;山之最高處,海之最深處,均能找到它們的蹤跡。不過,因?yàn)槲覀內(nèi)祟愃幍纳鷳B(tài)系統(tǒng)離不開細(xì)菌的活動(dòng),因而細(xì)菌扮演著重要的角色。正是由于他們強(qiáng)大的活動(dòng)力,我們?nèi)梭w需要的養(yǎng)份如碳、氮、硫等元素才能周而復(fù)始地循環(huán)。

    細(xì)菌是復(fù)雜而又迷人的單細(xì)胞生物,在最高沸點(diǎn)和冰點(diǎn)環(huán)境中均能存活。此外,細(xì)菌還是地球上最早出現(xiàn)的生命形式,他們形狀多樣,如棒狀、桿狀、圓形狀、螺旋狀等。這些細(xì)菌群生在一起,從而成雙、成鏈、成方,或者形成其他族群。細(xì)菌體積極小,只有通過顯微鏡才能看得見。

    那么,我們?nèi)绾卫眉?xì)菌創(chuàng)造藝術(shù)品呢?您不妨動(dòng)動(dòng)腦筋。細(xì)菌色彩天然,有些可含有像葉綠素般的色素,擁有綠、黃、橙、褐等天然顏色。如果細(xì)菌數(shù)以百萬計(jì)地組成多種菌落,就會(huì)呈現(xiàn)出粉紅、蛋黃等顏色,有時(shí)候還會(huì)呈現(xiàn)出白色。

    在細(xì)菌藝術(shù)創(chuàng)作中,科學(xué)家可能會(huì)將不同種類的細(xì)菌培育在皮氏培養(yǎng)皿中。皮氏培養(yǎng)皿是一種有蓋的圓柱型容器,生物學(xué)家利用這個(gè)蓋子來研究細(xì)胞?茖W(xué)家就是這樣研究細(xì)菌的特性,以便它們產(chǎn)生新的抗生素。接著,細(xì)菌形成菌落,從而構(gòu)成一個(gè)非常獨(dú)特的圖案,看上去就像一件擁有不同顏色的藝術(shù)品,也就是現(xiàn)在科學(xué)家所稱的細(xì)菌藝術(shù)品。
