Acetic acid bacteria (AAB) are a group of Gram-negative bacteria which oxidize sugars or ethanol and produce acetic acid during fermentation. The acetic acid bacteria consist of 10 genera in the family Acetobacteraceae. Several species of acetic acid bacteria are used in industry for production of certain foods and chemicals.
== Characteristics ==
All acetic acid bacteria are rod-shaped and obligate aerobes.
== Occurrence ==
Acetic acid bacteria are airborne and are ubiquitous in nature. They are actively present in environments where ethanol is being formed as a result of fermentation of sugars...
You’re already very close. You have realised that:
You can titrate the $\ce{Fe^{+II}}$ content with a potassium dichromate standard solution; and
You can turn $\ce{Fe^{+III}}$ into $\ce{Fe^{+II}}$ by adding metallic zinc.
Note that in the first bullet point of mine, your second reaction, you ...
The Beatles were an English rock band, formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. Rooted in skiffle, beat, and 1950s rock and roll, the Beatles later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways. In the early 1960s, their enormous popularity first emerged as "Beatlemania", but as the group...
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings is hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 70,000 member species, belongs to this order. They are found in almost every habitat except the sea and the polar regions. They interact...
リンゴ（林檎、学名：Malus pumila）は、バラ科リンゴ属の落葉高木樹。またはその果実のこと。植物学上はセイヨウリンゴと呼ぶ。
== 名称 ==
=== 学名 ===
栽培種には Malus domestica Borkh. という学名がある。主に、栽培種が複数の野生種の雑種であるという立場から使われる。
=== 和名・漢名 ===
日本語では漢字で主に「林檎」と書くが、この語は本来、同属別種の野生種ワリンゴの漢名である。また、「檎」を「ご」と読むのは慣用音で、本来の読みは「きん」（漢音）である。
リンゴ（セイヨウリンゴ）の漢名は「蘋果」である。「りんご」とも読むが当て字で、本来の読みは「へいか」である。
=== 英語名 ===
英語の"apple"はしばしばリンゴではなく果物全般を指す。たとえばパイナップル（"pineapple"）は「松の果実」という意味であり、リンゴとは直接の関係がない。
== 植物学上の特徴 ==
原産地は北部コーカサス地方とされている。リンゴは7500以上の品種が栽培されており、亜寒帯、亜熱帯及び温帯で栽培可能であるが、暑さに弱いため熱帯での栽培は難しい。リンゴの木は、落葉高木で晩春頃に白い5弁花が開花する。リンゴの果実は直径約3-15 cm、重さ約35-1000 g。外皮の色は赤や黄緑または黄色をしている。熟するとヘプタコ...

I have been on Chemistry Stack Exchange site for 6 months now and here's one thing that I have been having issues with since the time I first joined. It's those overly complicated answers some people give here just to be scientifically correct till the last detail. It is good to do that but not a...
Emoji (Japanese: 絵文字（えもじ）, Japanese pronunciation: [emodʑi]; English: /iˈmoʊ.dʒi/, plural emoji or emojis) are ideograms and smileys used in electronic messages and Web pages. Emoji are used much like emoticons and exist in various genres, including facial expressions, common objects, places and types of weather, and animals.
Originating on Japanese mobile phones in the late 1990s, emoji have become increasingly popular worldwide since their international inclusion in Apple's iPhone, which was followed by similar adoption by Android and other mobile operating systems. Apple's OS X operating system...
