The dried cells of micro-organisms used as food or feed were collectively defined as "microbial proteins" and in 1967 the term SCP ( Single Cell Protein) replaces term 'microbial protein'.
1. What is "totipotency"? The ability of a plant cell to perform all the activities of development like a zygote to develop into a complete plant is termed as totipotency. Haberlandt ,1902 first demonstrated totipotency by in vitro technique. 2. How do haploid plants produced? Haploid (n) plants are obtained by induction of embryogenesis during Anther and Pollen Culture. 3. How are haploid plants made Homozygous diploid ? 2/2020 BotH,TU The chromosome set of haploid pollen grains are first doubled by mutagenic chemicals like colchine (0.5% for 24-48 hr.). Then homokaryotic fusion resulted into production of homozygous diploid plants ( Vasil and Nitsch,1975). 4. What is Anther Culture?Describe the process with factors. Th...

A few important questions and answers for the students (1) What is spawn ? Spawn is a fungal growth medium that already has mycelial fragments of mushroom which is used by the mushroom growers as inoculum. Fig. A packet of paddy straw mushroom spawn (2) What are the different types of spawn ? Mushroom spawns are of different types:- (i) Natural spawn (ii) Milltrack spawn (iii) Brick spawn (iv) Flake spawn (vi) Tobacco spawn (vii) Grain spawn (3) Describe the method of spawning . Terrier (1945) first used wheat grain in spawning. Chang and Li, 1982 describe the following steps of grain spawning:- (i) Wheat grains are boiled first till it is half cooked, then water is drained off. (ii)To this 2% Calcium carbonate is mixed thoroughly. (iii) Then the mixture is transferred into glass tubes/ flasks. (iv)After plugging with non-absorbent cotton the mixture is autoclaved at 121°C for 30 minutes. (v) After cooling down to 30°C - 40°C , gr...
