3 Media Preparation for In Vitro Culture of Ganoderma

Rahmaningsih, M.; Virdiana, I.; Bahri, S. CABI PDF

Media Preparation for In Vitro

Culture of Ganoderma

3

Abstract

The preparation of growth media is the first step in isolating any microorganism (bacteria and fungi) from the environment. Media may be solid or liquid. The culture medium formulation will affect the success of mycelium growth in culture. Although there are many culture media described for fungi, only a few of them have proven to be excellent in culturing

Ganoderma. This chapter explains how to prepare the different media used in culturing Ganoderma isolates that cause BSR disease. The methods provided here are for 1 l of medium (Tables 3.1 and 3.2), which may be scaled up or down depending on capacity and the volumes required; a table is provided giving the volumes of media needed with respect to the required numbers of cultures (see Chapter 5 of this manual, Table 5.5).

3.1  Water Agar Medium

Water agar (WA) is the simplest agar medium (Himedia, 2015). WA is often recommended as it is cheap and supports spore germination collected from

Epilogue: Diving in the Cincinnatian Sea

Richard Arnold Davis Indiana University Press ePub

 

Many paleontologists, ourselves included, became fascinated with fossils and embarked on scientific careers long before we ever encountered living marine animals. For many of us, the greatest thrill has been our first encounters with living representatives of the animal groups we knew first only as grey, lifeless forms encased in rock. Both of us have been privileged to examine firsthand living relatives of animals of our favorite groups of fossils—crinoids for Meyer and nautiloid cephalopods for Davis. Our experiences have fueled a curiosity that affects practically anyone who contemplates the fossil richness of the Cincinnatian or other comparable fossiliferous strata. Many times, in the field, we stand on a Cincinnatian outcrop where fossils are abundant in almost every rock, and we wonder: what did the Cincinnatian sea actually look like? How did these creatures behave when alive? If we could travel back in time to dive into the Cincinnatian sea, what would we see?

In his book The Crucible of Creation, the paleontologist Simon Conway Morris (1998) takes the reader on a journey through time in an imaginary time machine that lands on the shores of the Cambrian sea in western Canada of 520 million years ago. The time machine then descends into the sea and enables time traveling scientists to view the varied and bizarre animals found as fossils in the famous Burgess Shale. Conway Morris recreated the environment of the Cambrian sea and the life within it from the evidence of the fossils and rocks, but he embellished the scenario with a measure of speculation and fantasy.

One Humanity’s Home in the Heavens

Garan, Ron Berrett-Koehler Publishers ePub

Humanity’s Home in the Heavens

On July 17, 1975, at 7:19 p.m. GMT, Soviet cosmonaut Alexey Leonov and American astronaut Tom Stafford reached across the hatches of their docked Soyuz and Apollo spacecraft and shook hands 140 miles above Earth. The event, which represented the end of a long, expensive space race and the beginning of a movement toward the peaceful exploration of space, was the end result of an agreement forged in May 1972, when President Richard Nixon and Soviet Premier Alexei Kosygin formalized a commitment to making a peaceful joint program of space exploration a reality. Speaking on the significance of this agreement, Soviet leader Leonid Brezhnev noted, “The Soviet and American spacemen will go up into outer space for the first major joint scientific experiment in the history of mankind. They know that from outer space our planet looks even more beautiful. It is big enough for us to live peacefully on it, but it is too small to be threatened by nuclear war.”1

4.1  The Australian Almond Story

4.1.1 History

The first recorded instance of almonds arriving in Australia occurred in the early 1800s, as food in the form of kernels or in-shell. An early advertisement in the Hobart Town Gazette and Van Diemen’s Land Advertiser of 27 July 1822 shows that

‘­Jordan almonds’ were imported to Tasmania and available for sale, presumably only for eating.

Other newspaper advertisements from The

Sydney Gazette and New South Wales Advertiser

(1804) tell of almond trees ‘of a particularly fine sort’ for sale by a nursery, coming from the

‘Cape’, presumably meaning Cape Town, South

Africa. Five years after the colony of South Australia was founded, Thomas Shepherd reported in the South Australian Magazine (1841) that several cultivars of almond were growing in the
