Bamboo bear

ジャイアントパンダ（Ailuropoda melanoleuca）は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指（橈側種子骨）を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急（VU）へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。

Viridibacillus arenisosiは種名が示す通り砂質土壌から分離された芽胞形成細菌です。特徴的な楕円形の内生胞子を形成し、比較的栄養分の少ない砂質基質でも生育できる能力で区別されます。この好気性化学有機栄養菌は砂質陸上環境での有機物分解において役割を果たします。
